BedairBotany and Microbiology Dept., Faculty of Science (Boys), Al-Azhar UniversityJournal Article20181117Sustainable agriculture is one of the most important strategies to overcome world hunger and food shortage. Soil deterioration due to mismanagement seems to be a major obstacle against achieving these goals. The present study aimed at assessing the physical and chemical quality of the soils in El-Menoufia Governorate for the cultivation of wheat which is commonly practiced. Seventeen soil profiles were selected to represent El-Menoufia Governorate soils in addition to 120 surface soil samples. Twelve physical and chemical soil parameters were chosen to evaluate soil quality including; soil salinity, exchangeable sodium, calcium carbonates content, pH, drainage, soil texture, depth, topography, surface stoniness, hardpan depth, hydraulic conductivity, and water holding capacity . Results showed variations among values of different parameters and localities. Interpolated thematic maps were produced for quantitative variables. Soil chemical quality index (CQI) and physical quality index (PQI) were calculated from the twelve investigated soil parameters. Results showed that El-Menoufia Governorate could be classified into two classes according to the physical quality measures (high and moderate), while results of chemical quality index revealed three categories (high, moderate and low). Over 85% of the soil of Menoufia governorate is of high physical quality while more than 89% is of moderate chemical quality for wheat cultivation according to both physical and chemical parameters. The results of this study are useful in planning land use management.https://jssae.journals.ekb.eg/article_36513_165063c44cc12ac28065daf8c8607ceb.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Effect of Organic Sources and Levels under Bio-Fertilization on Wheat Productivity and Soil Properties and its Fertility6997083651210.21608/jssae.2018.36512ENGihan MohamedSoil, Water and Environment Res., ARC, Giza, EgyptH.

The results reveal that compost had a slightly higher effect on wheat productivity and soil properties and its fertility than FYM. Increasing organic manure levels enhanced all studied growth, yield and yield components and N, P and K uptake in grains and/or straw, except 1000-grain weight which did not affect. Also, increasing manure levels improved all studied soil properties and fertility, except soil salinity which increased due to increasing manure levels. Bio-fertilization enhanced growth, yield and its component and nutrient uptake, except 1000-grain weight. All studied soil properties and fertility did not respond to bio-fertilization. Mixed bio-fertilizer with organic manure at a rate of 10 t/fed resulted in maximum wheat productivity and improved soil properties and fertility of soil after wheat harvest. https://jssae.journals.ekb.eg/article_36512_4ddc95ed8293967536d8eeb1ba5ba50e.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Effect of Irrigation Systems and Mulching on Summer Squash (Cucurbita pepo L.)

This study aimed to investigate the effect of two irrigation systems (surface drip <em>SDI</em> and subsurface drip <em>SSDI</em>), two types of soil plastic mulching (black plastic mulching <em>BPM,</em> and transparent mulching <em>TM)</em> plus a control treatment (no mulching <em>C</em>), and five levels of Elapsed time from germination to harvest (<em>ETime</em>); 58 days, 65 days, 72 days, 79 days & 86 days on the yield, growth parameters and water use efficiency (<em>WUE</em>) of summer Squash. The total fruit weight was almost the same for all treatments, but the distribution of fruit throughout the season were affected by the availability of excess water due to less evaporation caused by <em>SSDI</em> and the mulching. The maximum values of <em>WUE</em> were 2.01 kg /m<sup>3</sup> for the treatment with <em>SSDI</em> and <em>BPM</em> treatment. This treatment shortened the growing season and gave most of the plant fruit production between 65 and 75 days elapsed time since transplanting <em>ETime</em>.

Heavy metals were increased until 100% P-fertilization. All studied parameters under investigation were increased due to application of compost town refuse. So, it could be recommended for using both 75% from P-fertilization recommended dose and compost town refuse for optimum sweet pepper performance. Therefore, the organic fertilizers might help in reducing the need of high rates of P-fertilization to maintain proper P amount and also in reducing the expenses.https://jssae.journals.ekb.eg/article_36517_01f50783f2c07a5a73d6b43818c1abff.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Interference between Organic Soil Conditioners Mixed with Synthetic Soil Conditioners to Improve Sandy Soil Productivity7237343652010.21608/jssae.2018.36520ENHanaa Zein El-AbdeenSoil, Water and Environ.

The experiment was arranged in split plots design with three replicates. Five forms of organic soil conditioners were applied as main plot consists of control (NPK), yeast sludge (YS) at rate of 2 kgfed<sup>-1</sup>, commercial humic acids (HA at rate of 1 kgfed<sup>-1)</sup>, seaweed extract (SWE) at rate of 100 g fed<sup>-1</sup> and filter mud (FM) at rate of 5 kgfed<sup>-1</sup>). While the sub main plot using synthetic soil conditioners as zero addition, carboxymethyl cellulose (CMC) at rate 2% and polyvinyl alcohol (PVA) at rate 0.2 %. Results cleared that the interference usage of organic soil conditioners in combination with synthetic soil conditioners had positively affect hydro-physical properties of the soil, i.e., decreasing soil bulk density, increasing total porosity along with dry stable aggregate, as well as, the superior treatment is SWE + CMC. In general, there is no valuable difference between SWE and organic residues, whereas, YS and FM have the same trend over to control. In addition, organic matter (OM) and available macronutrients N, P and K content in soil were increased significantly with all treatments applied compared to control, the maximum increases were observed with SWE application mixed with CMC. An opposite trend was obtained with both pH and EC values which generally decreased at all applied treatments especially with (SWE+ CMC) Therefore, the application of seaweed as organic soil conditioner individually or mixed with CMC or PVA which increased significantly both wheat and peanut biological yields, straw grain and/or seed, along with total N, P and K content as compared to either control or other organic treatments application. Moreover, obtained results showed highly significant correlation ( p< 0.05) between grain and/or yield and soil EC, OM, P and N in spite of none significant correlation with pH and K. Finally, it can be concluded that organic soil conditioner especially seaweed and sugar cane byproduct was enhanced and became more effective when applied with polymers especially CMC.https://jssae.journals.ekb.eg/article_36520_52269a89aa109bbc1c797fb0af79bfbe.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Maximum Utilization of Organic Wastes as Soil Amendments and its Effect on Physical and Chemical Properties of Sandy Soil7357413651410.21608/jssae.2018.36514ENWagida HassanSoil, Water and Environ.

Selenium (Se) is an essential trace element for humans and animals and appears to be a beneficial element for many plants. There is increasing evidence showing that low selenium (Se) concentrations may build resistance of plants to environmental stresses. For this purpose, a pot experiment was carried out at The Experimental Farm of the Faculty of Agriculture, Mansoura University, Dakahlia Governorate, Egypt, during the spring season of 2016, to investigate the potential alleviation of salinity adverse effects by Se application as a foliar spray in the form of selenium nanoparticles (Se-NPs) in two concentrations (0 and 50 ppm) on coriander (<em>Coriandrum sativum</em>) grown on a sandy soil irrigated with different concentrations of saline water S1 (EC<sub>w</sub>=3.12 dS m<sup>-1</sup>), S2 (EC<sub>w</sub> =6.25 dS m<sup>-1</sup>) and tap water as a control S0 (EC<sub>w</sub>=0.45 dSm<sup>-1</sup>). These experimental treatments were arranged in a split plot design in three replications. Salinity showed adverse effects on different plant growth parameters as well as total chlorophyll content. Selenium nanoparticles (Se-NP1) at 50 ppm showed the best effects on vegetative growth and total chlorophyll content of coriander plants under different salinity levels of irrigation water. Increasing salinity resulted in decreasing N and K contents in the leaves of coriander plants, but Na increased as a result of some sort of antagonism with K; in spite of that, N and K contents in coriander leaves increased with foliar application of selenium nanoparticles (Se-NP1) at rate of 50 ppm to be higher concentrations compared to distilled water added to the spray as a control 0 ppm (Se-NP0). Values of Na/K ratio in coriander leaves increased as the salinity levels increased while, K/Na ratio was decreased. On the contrary, the values of Na/K ratio decreased with (Se-NP1) spraying at rate of 50 ppm, but K/Na ratio was increased at the same spraying rate under all salinity levels. It is concluded that application of selenium nanoparticles can mitigate salt stress damages on coriander plants; it also leads to increasing in K concentrations and decreasing in Na concentrations under salt stress.https://jssae.journals.ekb.eg/article_36530_257efef6832d625486c37e01bfb1d775.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Effect of Partial Substitution of Mineral Nitrogen Fertilizer by Farm Compost on Soil Fertility and Productivity7617643652510.21608/jssae.2018.36525ENM.

The experiment was established and designed statistically as a split plots with three replications. The main plots involved tillage treatment levels of rotary plough as a minimum tillage, moldboard plough followed by disc harrow and chisel plough (two perpendicular passes) followed by disc harrow as a conventional tillage. The sub plots included soil mulching treatment levels of black, white and transparent polyethylene sheets (30 micron thick), comparing with bare soil. The results indicated that the rotary plough accomplished the higher actual field capacity of 0.92 fed/h and the lower specific energy requirements of 25.43 MJ/fed. While, the moldboard plough followed by disc harrow achieved the moderate soil mean weight diameter of 84 mm. The moldboard plough followed by disc harrow system accompanied with the transparent polyethylene sheet achieved the higher values of both the soil moisture content and the weed control efficiency at the periods of 7, 30 and 60 days after planting. Also, it recorded the higher sesame seed yield of 1.26 ton/fed.

The current study was performed to assess the effects of applied fertilizers to tomato grown at Fayoum Governorate Egypt (29° 18<sup>'</sup> 30"N; 30° 50' 39"E) on yield, nutrients uptake, nitrate accumulation, soil fertility, and the relationships among them. Eighteen tomato fields were chosen at four villages in two districts at autumn season of 2016-2017. Representative samples of soil, plant and irrigation water were taken from every site to be analyzed. Furthermore, 120 questionnaires forms were collected from tomato farmers in the studied districts. Results indicated that soils under study were high in nitrogen and most of micronutrients, low in phosphorus and moderately to low in potassium. Irrigation water quality ranged from low to moderately. The total productivity of tomato ranged from 19.350 to 46.548 t. fed<sup>-1</sup> with an average of 31.096t., where the added fertilizers ranged from 147-259 kg N fed<sup>-1</sup>, 22.5-75 kg P<sub>2</sub>O<sub>5</sub> and 0-96 kg K<sub>2</sub>O. Tomato yield significantly correlated with applied fertilizers of N, P and K, but insignificantly correlated with organic manure. The accumulation of nitrate in fruits significantly correlated with uptake of nitrogen, nevertheless the correlation between the applied of nitrogen and the uptake was insignificant. The obtained data of questionnaires forms cleared up that correlation between tomato productivity and the added nitrogen and organic manure was insignificant. Therefore, great attention should be paid to phosphorus and potassium fertilization without excessive addition of nitrogen.https://jssae.journals.ekb.eg/article_36541_ff66ddabcaf55b2233946a5675a55c17.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Integrated Management of Wheat under Dry Land Conditions7817913653710.21608/jssae.2018.36537ENM.

A field experiment was conducted in Om-Elrakham, Marsa Matrouh Governorate, Egypt during winter season 2016-2017 and repeated in 2017-2018 to examine the effect of various farming practices on wheat production under dryland condition. The treatments were 1) supplemental irrigation treatments (rainfed, 60% of water requirement (SI<sub>1</sub>) and full requirement (SI<sub>2</sub>)), 2) two hydrogel applications (with hydrogel (H) and without hydrogel (H<sub>0</sub>) addition) and 3) three fertilization treatments (control (F<sub>0</sub>), traditional mineral fertilizers (TF) and slow release fertilizer (SRF) application) on wheat production. The obtained results indicated that wheat production increased gradually with applied supplemental irrigation in the following order: SI<sub>2</sub>> SI<sub>1 </sub>> rainfed. Hydrogel treatment led to an increase in wheat grain yield by 19.1, 14.8 and 9.4% under rainfed, SI<sub>1</sub> and SI<sub>2</sub>, respectively compared with H<sub>0</sub> treatment. Generally, the addition of hydrogel enhanced the studied soil physical properties. Slow release fertilizer superior to traditional fertilizers that enhanced wheat yield compared with control (F<sub>0</sub>). Although increasing applied water led to decrease IWUE, the addition of hydrogel and slow-release fertilizer raised both of irrigation water use efficiency (IWUE) and economic water productivity (EWP). Interestingly, the interaction SI<sub>1</sub>xHxSRF (1274.5 and 1276.0 kg/fed.) produced higher grain yield than SI<sub>2</sub>x H<sub>0</sub>x F<sub>0</sub> (928.0 and 995.1 kg/fed.) and SI<sub>2</sub>x H<sub>0</sub>xTF (1207.0 and 1206.7 kg/fed) in the first and second season, respectively. Thus, it can reserve about 40% of added water by using hydrogel and slow release fertilizers with SI<sub>1</sub> (60% of water requirements) under the studied soil conditions. It can address the challenges of wheat production under dryland conditions by the integration between supplemental irrigation, hydrogel, and slow-release fertilizers. https://jssae.journals.ekb.eg/article_36537_8d41d16370ef013bc835469f0dd987a5.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Performance of a Maize Chopping Machine with an Attached Sharpener Unit7937983653310.21608/jssae.2018.36533ENA.

Box 256, Giza, EgyptJournal Article20181202In the workshops of agricultural sector there are a lot of technical jobs which widely use hand-held or bench-top workshop power tools such as angle grinders, drills, riveters, chain saw, pneumatic hammers and torque wrenches. Which consider the most important sources of hand arm vibration (HAV) These workshop power tools are known to transmit substantial vibrations to the operators/worker's hand and arm and act as vibrations resource consequently, create problems for operators/workers who regularly exposure to hand arm vibrations. Therefore, the main objective of this investigation is to study the effect of frequently using of workshop tools on worker's hand arm vibration and safety. The study selected eight representatives healthy workers were well familiar with the workshop power tools control levers and had sufficient experience of operating some power tools from both bench-top and hand held workshop power tools (stand drill, wheel grinder, disc cutter, angle grinder impact drill, and rotary hammer drill with different spare discs under two different working postures as vertically erected and squeeze) during five different operations, namely, grinding, drilling, cutting, breaking and polishing using three types of materials (metal, wood and concrete). Parameters such as frequency-weighted vibration acceleration in root mean square (RMS), heart pulses rate (HR), blood pressure (BP), work related body pain (WRBP), stand height, arm length and mass of operators were evaluated. Vibration measurements were performed according to (ISO 5349-2: 2001). Workshops operations were conducted in a statistically designed layout (randomized complete blocks design) and were conducted at applied research farm of Rice Mechanization Center, Meet Eldeeba, Kafr El-Sheikh Governorate, in the 2018. The obtained results indicated that the cutting by the angle grinder gives the highest HAV data of the frequency weighted RMS acceleration magnitude while, the largest single orthogonal axis is in the axis (X) which exceeded than both of exposure action value and exposure limit value. This causes a high risk on the worker hand-arm which increases the heart rate and blood pressure followed by the polishing by the hand angle grinder. On the other hand, the HAV emission level recorded the lowest values during grinding by the bench-top wheel grinder and drilling by the bench-top stand drill consequently; there is no risk on the operator hand-arm and also the heart rate and blood pressure. Using rubber gloves during cutting by the hand angle grinder leads to a decrement percentages in the HAV values and so heart rate and blood pressure. The maximum WRBP values were obtained during the cutting by the angle grinder on working squeeze posture followed by cutting by the angle grinder on working normal posture and polishing by the angle grinder. Maximum pain levels of 15.6, 14.8 and 13.6 (Borg scale) were observed respectively. Results showed that there are significant differences between RMS, SBP, DSBP and heart rate during the different workshop operations.https://jssae.journals.ekb.eg/article_36523_669d8781822793b3f235eeda4c846f10.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Groundwater Quality Assessment for Irrigation Purposes in the West of Minia, Governorate, South Egypt b8098163651110.21608/jssae.2018.36511ENI.

IsmailSoil, water and Environment InstituteGhada Abdel-KaderSoil, water and Environment InstituteJournal Article20181206This investigation has been conducted to assess the suitability of ground waters in west Minia governorate for irrigation purposes. Thirty-three groundwater samples were collected from different sites, along Assiut the West Desert Road. These samples were analyzed for water quality criteria, namely electrical conductivity (EC), soluble cations (Ca<sup>2+</sup>, Mg<sup>2+</sup>, Na<sup>+</sup> and K<sup>+</sup>), anions (HCO<sub>3</sub><sup>-</sup>, CO<sub>3</sub><sup>2-</sup>, Cl<sup>- </sup>and SO<sub>4</sub><sup>2-</sup>). The chemical parameters that control water quality such as sodium adsorption ratio (SAR), soluble sodium percent (SSP%), residual sodium carbonated (RSC), Kelley’s ratio (KR), potential salinity (PS), permeability index (PI), total alkalinity, total hardness, magnesium ratio were also calculated using standard equations. Results revealed that anions contents in the studied ground waters followed the sequence: SO<sub>4</sub><sup>2-</sup>>Cl<sup>-</sup>> HCO<sub>3</sub><sup>- </sup>whereas CO<sup>-3</sup>ion was not detected. On the other hand, the cations contents of the water samples followed the sequence: Na<sup>+</sup>> Mg<sup>2+</sup>> Ca<sup>2+</sup>> K<sup>+</sup>. In addition, the pH values of the studied water samples ranged between 6.9 and 7. 9. The analytical results indicated that 94 % of the groundwater samples can be classified as good for irrigation on bases of EC, SAR, RSC and SSP%. Both SAR and RSC values indicated no liability for sodicity hazard. However, groundwater samples had high salinity levels and low sodicity (C3–S1). Some other parameters, which were generally used for assessing water quality e.g. Irrigation Water Quality Index (IWQI) and Relative Crop Yield Potential (RCYP), were calculated. GIS was used to create a water quality database including spatial distribution map for each parameter. The results obtained herein showed that about 21 % of the groundwater samples belong to No Restriction category (NR) while about 79 % from the total samples belong to the Low Restriction (LR) category. According to the RYPC values calculated for some crops that can be cultivated using the investigated waters, the following sequence is obtained: sugar beet (94) > wheat (74) > corn (33) > bean (13). Thus, it can be concluded that the studied groundwater can successfully be used for irrigation with special salinity control management i.e. leaching requirements and salt tolerant plants.https://jssae.journals.ekb.eg/article_36511_48b8a60da4e71a13165300b41ec82ddb.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Development of a Combine Hoeing Machine for Flat and Ridged Soil8178203654810.21608/jssae.2018.36548ENM.

SolimanSoil Department, Faculty of Agriculture, Damietta University, EgyptJournal Article20181211Wheat is one of the most important strategic crops needed for food and feeding. Due to its importance, this work aimed to demonstrate the role of organic/mineral N sources in collaboration with bio-fertilizer inoculation in enhancement of wheat growth and yield under low fertile sand soil with special emphasis to economical and environmental impacts. Field experiment was conducted on sand clay loam soil using wheat (<em>Triticum aestivum</em> L., Sakha 93) exposed to different rates of mineral nitrogen fertilizer either solely or in combination with different rates of organic compost. Fertilization treatments were applied with or without <em>Azospirillum brasilinese</em> as a representative of plant growth promoting rhizobacteria (PGPR). Tested treatments were completely randomly distributed in statistical factorial block design. Application of nitrogen fertilizer at full dose (120 kg N fed<sup>-1</sup>), induced higher grain yield and nutrient uptake (NPK) than those recorded with other low mineral-N levels. Both plants fully treated with organic compost or in combination with levels of mineral nitrogen achieved grain yield and nutrient acquisition nearly closed to those of moderate mineral-N level. Relatively, inoculation with <em>Azospirillum brasilense</em> resulted in higher grain yield by about 25% over an un-inoculated plants. Nitrogen uptake by grains and straw significantly increased by increasing nitrogen fertilizer rates and inoculation treatment. Phosphorus and potassium contents not responded to <em>Azospirillum</em> inoculation but enhanced with increasing nitrogen fertilizer rates and application of organic compost. Combined treatments had enhanced nitrogen portion derived by either grains or straw from mineral-N form. Inoculated plants compensated remarkable amounts of nitrogen via N<sub>2</sub>-fixation. Low amounts of nitrogen released from compost were derived to grains of inoculated and uninoculated plants but it increases with increase of compost component in the combined treatments. Nitrogen use efficiency (NUE) by either grains or straw of the inoculated plants was tended to increase with decreasing N fertilizer rates either individually or in combination with compost. Application of medium to low mineral N in combination with organic compost lowered the portion of N losses and achieved positive N balance. This phenomenon was more vigorous with combined treatment of 75% mineral plus 25% organic compost under the uninoculated treatment. Negative N balances were observed with sole addition of mineral nitrogen and tended to decline with reduction in nitrogen fertilizer rates. These trends were lower in case of the uninoculated plants than inoculated one.https://jssae.journals.ekb.eg/article_36519_11a7ff175db0d402f0c6aa9cccc7ad82.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Effect of Gypsum, Sulfuric Acid, Nano-Zeolite Application on Saline-Sodic Soil Properties and Wheat Productivity under Different Tillage Types8298383655210.21608/jssae.2018.36552ENA.

SeleimanDepartment of Crop Sciences, Faculty of Agriculture, Menoufia University, 32514, Shibin El-kom, EgyptJournal Article20181212Soil degradation due to soil salinity and sodicity is considered a serious concern in arid and semiarid ecosystems. Due to arid climate even, normal soils are converted to saline-sodic soils. Recently, reduced tillage proved successfully increasing soil organic matter contributing to soil carbon sequestration leading to improvements in soil physical and chemical properties. However, exploring effect of reduced tillage in saline sodic soils, even under amendments application has less attention so far. Therefore, the present study was conducted to investigate the combined effects of inorganic soil amendments (Nano zeolite, sulphuric acid and gypsum) and tillage systems (reduced and deep tillage) on saline-sodic soil physical and chemical properties and wheat productivity. Deep tillage with sulphuric acid application significantly reduced soil electrical conductivity (EC), exchangeable sodium percentage (ESP), penetration resistance (PR) and bulk density (Bd) and increased soil hydraulic conductivity (HC), mean weight diameter (MWD) and aggregation index (AI) compared to control. Deep tillage showed a significant improvement of saline-sodic soils, despite increasing SOC with reduced tillage. Moreover, sulphuric acid, gypsum and Nano-zeolite applications with deep tillage increased wheat grain yield significantly compared to control. Nano-zeolite application gave the superiority in increasing soil organic carbon compared with sulphuric and gypsum, enhancing wheat productivity to be close to yield under gypsum application without significant differences. Nevertheless, application of Nano-zeolite in improving saline sodic soils not preferable economically compared with sulphuric acid and gypsum. In conclusion, sulphuric acid, gypsum applications in combination with deep tillage improved physical and chemical properties of saline-sodic soils, and consequently enhanced growth and yield of wheat, confirming the importance of deep tillage in reclaiming saline-sodic soils compared with reduced tillage.https://jssae.journals.ekb.eg/article_36552_5606211b1fee5bc40d3a05e9961ce7af.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Effect of Adding Crude Glycerol Produced from Biodiesel Industry on Biogas Production from Anaerobic Digestion of Cattle Dung8398453652810.21608/jssae.2018.36528ENM. ZayedAgricultural Engineering Research InstituteJournal Article20181214Effect of crude glycerol addition to cattle dung on biogas generation and methane percentage was studied. Five percentages of crude glycerol were added to cattle dung during the anaerobic digestion process. The crude percentages ranged from 1 to 5% based on total solids (from 4 to 20 g). The experiments were conducted at mesophilic conditions of ambient temperature (27±2ºC) and 40 ºC. Twelve batch-digested units were used for laboratory experiments procedure. The digested units were divided to two groups with six digested units for everyone. The first group was operated at ambient temperature (27±2 ºC). While, the second group was operated at Forty degree centigrade. The full capacity of each digested unit was 5 Liters while, the working capacity was 4 Liters. The digester feeding consists of 3.2 L of cattle dung and 0.8 L of inoculum. Five digesters of every groups were fed with different percentages of crude (from 1 to 5%) namely G1, G2, G3, G4, and G5 in addition of G0 (control digester with 0 percentage of crude).The obtained results showed that the addition of crude glycerol to cattle dung during anaerobic digestion increased the biogas production rate and consequently the total biogas production at different temperature levels. Moreover, increasing the percentage of crude glycerol added increase the biogas production reached the maximum average biogas production rate of 0.212 and 0.296 L/L/day at G5 (5% crude glycerol added about 20 g) and different temperature levels of 27 ºC and 40 <sup>°C</sup> respectively as compared with G0 (0 crude glycerol added). The increasing ratios were; 13.60 and 17.89% at the same temperatures respectively. Moreover, the total biogas production reached the maximum values of; 51.489 and 59.279 L at the treatment of G5 and the same temperatures respectively, with increasing ratios of 14.27 and 18.08% at the same temperatures as compared with G0. The maximum value of methane content was 66% with increasing ratio of 8.28% and it was occurred at 5% crude glycerol and temperature of 40 ºC.https://jssae.journals.ekb.eg/article_36528_0a36b0c352bdca8dbfb08658a5c5816a.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Changes of Water Retention in Rice Soil Amended with Organic Manures under Irrigation by Saline and Sodic Water8478573654310.21608/jssae.2018.36543ENEnas SolimanSoils Dept., Fac.

Evaluate such an impact plays a vital role in the achieving of effective development of soil and water maintenance and management practices. Therefore, a field trial was performed to evaluate the effects of irrigation water qualities and organic manures amendment on the soil water potential as a limiting factor of crop production. The treatments consisted of all possible combinations of three types of organic manures (2 t fed<sup>-1</sup> rice straw compost, 5 t fed<sup>-1</sup> farmyard manure (FYM), and 2 t fed<sup>-1 </sup>rice straw compost + 5 t fed<sup>-1 </sup>FYM) beside the control and three types of irrigation water differed in salinity (EC) and sodicity (SAR<sub>Adj</sub>), that were industrial wastewater, agricultural drainage water and freshwater. The investigated treatments influenced the shape of the soil-water characteristic curves (sorption and desorption) and had considerable effects on the aggregate stability as indicated by the patterns of hysteresis phenomena. The variation of irrigation water quality had the strongest effect on modifying soil properties, especially agricultural drainage water having the highest SAR<sub>Adj</sub> then industrial wastewater with the highest EC. In addition, mixing compost with FYM is considered the best improver for soil irrigated with poor quality water under these experimental conditions.https://jssae.journals.ekb.eg/article_36543_bb05894b36520e7a4b898624e54cb2be.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Thermal Properties of Palm Fronds (Krino) for Utilizing as a Thermal Insulation Material8598633655410.21608/jssae.2018.36554ENN.

The cost of insulation materials is a large part of the initial, maintenance and repair costs. Glass-wool insulation namely exchanges in a short time due to its absorption of moisture resulting in decreasing the insulation value. Disposal of glass-wool insulation material constitutes an environmental problem due to its difficultly of degradation. The palm leaves are considered as a great field residues annually produce in Egypt and the Arab countries when each palm produces more than 25 kg per year and the number of palm trees in Egypt is more than 17 million palms. These field residues are rich in cellulose, sugars and many other important elements that can be used in different industries or extraction of important natural materials, which provide return an economic benefits instead of burning them. To achieve the goal of this research, four cylindrical metallic tanks made of black iron sheet, each one having gross dimensions of 50 cm long, 30 cm in dimeter, and 1 mm thick. Three tanks were thermal insulated using krino as an insulation material, with three different densities of insulation (50, 60, and 70 kg/m<sup>3</sup>) and 5 cm thick. The fourth tank was insulated using 5 cm thick of glass wool. The most important results of the thermal conductivity test of krino revealed that the thermal conductivity of the krino depends on its density and temperature. The best density was 50 kg/m<sup>3</sup>. The values of thermal conductivity of the three different densities was ranged between 0.0954 and 0.190 W/m K)https://jssae.journals.ekb.eg/article_36554_0d4a7ebd3a1a6f91a1093620454ba902.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Chitosan and Soluble Calcium Effects on Plant Systems under Salinity Stress8658716997310.21608/jssae.2018.69973ENM.

KhalifaSoils, Water & Environment Research Institute, Agric. Res. Centre (ARC), Giza, EgyptJournal Article20181221Soil salinity is one of the important environmental factors that impair the agricultural production, while the application of some amendments such as soluble calcium alleviates the adverse effect of salinity on plant growth. The objective of the present study was to evaluate the interactive effect of soil application of soluble calcium (sol. Ca) (2 or 4L/fed) and foliar application of chitosan (CHT) (0.5 or 1L/fed) on maize productivity, NPK absorption and some soil properties under salt stress (8.27 dS/m for soil and 2.9 dS/m for irrigation water). The experiment was carried out at Sakha Agric. Res. St. Lysimeter, Kafrelsheikh governorate, Egypt, during summer season (2018). The obtained results proved that these amendments individually or in combination markedly improved the growth and yield of maize (plant height, grain filling, and cobs and straw yields), enhanced N, P and K concentration (in grain and straw) and ameliorated some chemical properties of salt affected soils(ECe, SARe and ESP). It was, therefore, found that the application of higher levels of sol. Ca and CHT in combination significantly affected the plant growth and caused the highest increases in plant height (65.1%), 100- grain weight (112.2%), cobs and straw yields (168.4 and 111.6%, respectively). In addition, this combination achieved the highest NPK contents in grain (3.51, 0.33 and 1.08 %, respectively) and straw (1.73, 0.14 and 1.62 %, respectively). Also, the application of sol. Ca and CHT as well as in combination slightly decreased soil ECe, SARe and ESP values. In general, soil application of sol. Ca and foliar application of CHT ameliorated the adverse effect of salinity on maize productivity, and the combined application of them was more positive effective on plant growth under salt stress.https://jssae.journals.ekb.eg/article_69973_6f80c0147ce857340052224aeebb0b56.pdfMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368591220181201Exploratory Properties and Restrictions of El-Zayat Soils for Agricultural Sustainability, El-Dakhla Oasis, Egypt8738796997510.21608/jssae.2018.69975ENM.

The results revealed different soil texture classes (clay, sandy clay loam, clay loam, sandy loam and silty clay loam). The calcium carbonate and organic matter contents varied from 9.8 to 85.6 and from 0.8 to 10.2%, respectively. Cation exchange capacity (CEC) ranged from 4.8 to 71.6 cmol/ kg with an average value of 34.92 cmol/ kg. The pH values differed from neutral to moderately alkaline. Additionally, 10% of the collected samples were slightly saline, while 30.0 and 60.0% were moderately and strongly saline, respectively. Sodium adsorption ratio (SAR) for 70% of the collected samples realized values > 13 indicating sodic soils. The total nitrogen in the tested soil samples is very low. Concerning available phosphorus, about 53, 30 and 17% of tested soil samples were low, medium and high, respectively. The available potassium (K) for 98% of the tested soil samples was very high. Suitable gypsum requirements should be added to reclaim these soils which need a management program to overcome these problems. Also, organic manures have to be applied to improve the soil properties and enrich their nutrient status.https://jssae.journals.ekb.eg/article_69975_15292e04f7d3c8617b03d04b328aeee0.pdf
