| Abstract | ||
| Some Physical and Chemical properties of sandy soil for defferent periods of cultivation were determined. The study include a non-cultivated, 1-year, 3-years, 6-years, of used to test for this influence such as hydraulic conductivity , water content , bulk density , and mean weight diameter . hydraulic conductivity and water content significantely increased from 0.20-0.42 cm.min-1 and from 19.80%-25.24% respectively as a result of 6 years of cultivation . Bulk density decreased from 1.61 mg.m-3 to 1.36 mg.m-3 for the first debth ( 0-15 ) cm of non-cultivated and 6 – years of cultivation, respectively. . organic matter and electrical conductivity increased from 0.18% to 0.39% and from 2.0 ds . m-1 to 13.0 ds . m-1 for the non-cultivated and 6 years of cultivation, respectively Cumulative infiltration was also affected by the agricultural practices . kostiakov equation was used to describe the infiltration data . | ||
