The Effect of Soil Depth and its Management on the Stability of Soil Aggregates of Different Pedons in Basra Governorate

Abstract

Abstract Four soils were selected by different departments of Basra Governorate, namely Abu Al-Khasib, Al-Tanuma, Al-Nashwa, and Al-Deir (i.e., cultivated and uncultivated) in the area confined between longitudes 30.980 and 47.460 N and latitudes 30.452 and 47.967 E for the study. Estimation of soil stability of eight cultivated and uncultivated Bedoons. In the province of Basra, in addition to studying some chemical properties such as organic matter and calcium carbonate, The results showed the effect of soil management on the average weighted diameter and the organic matter, where clear differences were found in the soil layers, especially in the cultivated areas compared to the uncultivated areas, especially in the surface layers of Abu al-Khasib and. Bedons al-Nashwa, while it decreases in the surface layers of Pedon l-Deir and Tanumah, and excludes among them the Bedons Abu al-Khasib. It is not cultivated as it decreases in the surface layer and increases with depth compared to other crops due to the presence of palm roots.
