AbstractThe experiment was conducted during spring season 2016 in two type's soils textures, the first one was held in college of agriculture-Baghdad University (abu-Grhaib) which is silty clay loam, The second texture of soil was silty loam. The purpose is to study the effect addition for different levels of organic matter in some infiltration rate and basic infiltration rate, the experiment includes two factors; first factor includes two levels for organic matter, addition 20 tan. ha-1 L1, 40tan. ha.-1 L2 and control treatment L0 (without organic matter), the other factor includes two texture of soil , Silty clay loam T1 and silty loam T2, these levels of organic matter was mixed of the surface soil until the depth 0.75m before measuring the infiltration.
The results showed that values of accumulative infiltration were increased at 18.80, 23.00% by addition of highest levels of organic matter to the silty clay loam soil and silty loam soil, respectively. The values of infiltration rate were increased up to 31.97, 34.74% for the two texture of soil silty clay loam and silty loam, respectively. The values of basic infiltration rate were increased up to 18.00, 31.82% by addition of the highest level of organic matter to the two textures of soils silty clay loam and silty loam, respectively.
