To study and identify soil minerals in the arid regions of Iraq, a transect of seven pedons distributed in Pripj region, which forms the largest trough in the southern desert of Muthanna province, was selected, the pedons were morphologically described and obtained disturbed soil samples from every horizon for the purpose of conducting some mineralogical analysis. Results of mineralogical analysis of the very fine sand showed supremacy of the light minerals, which formed more than 93% in comparison with the heavy minerals. The light
The study dealt with one of the most important environmental problems that leads to soil deterioration, increase in the degree of desertification and the loss of large areas of lands that suffer from dry and semi-arid areas. This study aims to calculate the amount of soil transported using the revised universal equation model of erosion RUSLE, and five representative surface samples were obtained. For all the watershed of the valley, analyses were carried out for the general equation of erosion, and the climatic data of the Anah meteorological station were used, whose values ranged between (0.0554-0.4923), as well as the values of normalized difference vegetation index (NDVI) between its high and low values (0.10084-0.645161). Maps were created from the general equation factors (RUSLE) and their units were classified according to water erosion rates to investigate the susceptibility of soil to erosion and the risk of soil erosion.
To study the genesis and developments of illuviation horizons in Iraqi arid region, three pedons were selected in the Pripj region bottom, which formed the larger region in Iraqi southern desert in Muthana governorate, the pedons were من مستل البحث أطروحة الثالث للباحث اه دكتور
This study have been conducted to know the effects of rainfall intensity, land slope and Bitumen & wheat straw addition on the changeability of soil bulk density and modulus of some soils at western Iraqi soils under simulated rainfall. Soil samples have been taken from (0-30cm) depth for four regions which are: Zangora, Mhammadi, Madheek and Heet whose erodibility classes are; high, moderate-high, moderate and low respectively. The samples air dried and sieved through 4 mm diameter sieve then situated in experimental flumes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
