The rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. However, plants in general may have a different ability to sustain soil. The objective was to determine the effects of reclamation practices including Haloxylon ammodendron and Atriplex canescens plantation o...
Abstract Soil functions such as water storage, soil filtration, and reducing reservoir life due to sediment load are directly affected by the process of “soil erosion.” The Universal Loss Equation was adopted predict erodibility factor for watersheds feeding Al-Shewicha trough. K -average factor’s determined value 0.156, indicating that -factor had substantial variability. values linked high sa...
We tested an efficient, easily and economically manufactured wind-transported particle collector of our own design, called a multidirectional trap (MDt), on fine-tilled Anthrosols. Results from the logs nine vaned masts, each with four MDt collectors at different heights, showed clear predominance northeast south winds. After analyzing sediment transport rates their balance, we found that sedim...
The reclamation area on ex-coal mining land is very vulnerable to erosion. Soil vulnerability comes from the physical properties of soil, ease with which it erodes, and topographical conditions. Erosion occurs in open areas little overgrown vegetation. However, this condition course a fundamental consideration factors that influence This type research descriptive quantitative research, obtained...
Abstract Functions and services provided by soils play an important role for numerous sustainable development goals involving mainly food supply environmental health. In many regions of the Earth, water erosion is a major threat to soil functions mostly related land-use change or poor agricultural management. Selecting proper management practices requires site-specific indicators such as erosio...
Soil's resistance to erosion or its susceptibility resist detachment is a key parameter in the majority of soil and sediment models. Although function both intrinsic properties dynamic environmental variables (e.g., moisture), influence latter seldom explicitly incorporated definition resistance. The significant complex role moisture content on recognized by many studies, however, much emphasis...
