Abstract
The solid wastes of city represent an economic value for its free raw materials included which can be recycled and accessed into a number of industries in which organic materials could be composted and transferred to organic fertilizer represent 60% from the total solid remnants . So that ,the idea of the current study is aiming to study the impact of adding an organic fertilizer extracted from city garbage on some characteristics of the physical soil . A simple experiment has been designed including a lonely factor under studying which is the city waste compost fertilizer of the organic remnants at four different levels with control : 0,10,20,40 tons /hectares . The experiment was carried out during the spring season of 2008 at the Educational Farm , Faculty of Agriculture , Sana'a University . A complete randomized block design was used in three replicates. The addition of organic fertilizer led to reducing the bulk density of soil and increasing the addition rate . The Bulk Density value reduced to 1.23 g/cm3 at added 40 tons /ha compared with 1.35 g/cm3 for control , and has also led to a significant increase in the Hydraulic Conductivity of the soil at the level of added 40 t / ha . as the value of hydraulic conductivity of 3.80 cm / hour , compared with 3.65 cm / hour to control . and has also led to a significant increase in soil porosity was 53.35 % at added 40 t / ha. also resulted a significant increase in the proportion of available water , where the percentage of available water was 8.73 % at the level of 40 tons / ha compared to 8.44 % for the control. and caused . A significant increase in plant height was observed ,where the values of plant height were 171& 182 cm when add 20&40 t / ha , respectively, and also significant increases in both the number of leaves per plant dry matter weight per plant compared to the control .
