Abstract
The limited natural resource of water in Sinia is one of the major problems in agriculture sector. To study and evaluate the different water quality of some wells in North Sinia, a field investigation was performed by chosing 20 sites of soils which irrigated from besidly wells for a long time at El-Arish, Rafah and Sheikh Zuwayid. Water and surface soil samples were taken and analyzed. Simple linear regression relationships were conducted between some properties of wells water and soils. The important results could be summarized as follows:
Irrigation water of wells at all locations have very and severe hazards of salinity and sodicity and they lie in categories between (C3 – S1) and (C4 – S4). Water content of soluble Fe, Mn, Cd and Pb are higher than the safty limits in all locations. Soluble NH4+, NO3- and NO2- in water wells are less than the critical concentration of safe using.
Soils which were sandy and loamy sandy were found non-saline in most locations as affected by irrigation water quality. Soil content of available Fe, Mn, B, Pb, Cd, NH4+, NO3- and NO2- were low in all locations except NH4+and NO3- in soil around well No. 16.
A high negative correlation was found between, soil-pH and both of available Fe and Mn in soil (- 0.634** & - 0.732**) and between CaCO3 and available soil boron (- 0.489*). Also, a high significant postive correlation between water-pH and available soil boron was found (0.656*).
Finally, wells water can be used for irrigation purposes in the area of study under control and with good a management(optimum tillage, adding organic matter and amendements and good croping system etc..).
