Soil erosion is one of the vital factors contributing to the loss of fertility and environmental degradation. Generally accepted diagnostics of eroded soils is based on comparison of the sloping soils profile depth with the watershed soils. In this case, there is a separate problem of slope soils with a naturally shortened profile and eroded soils. Formation of the soil’s natura...

Soil erosion has been a problem in agriculture since ancient times. The main impact of erosion on the soil is a loss of soil productivity because of decreased capacities in soil biological, chemical, and physical properties. Various researchers have reported reduced crop yields in eroded soils (Frye et al., 1982; Olson and Carmer, 1990; Chengere and Lal, 1995; Shaffer et al., 1995). This loss i...

Soil erosion and terrestrial deposition of soil organic carbon (SOC) can potentially play a significant role in global carbon cycling. Assessing the redistribution of SOC during erosion and subsequent transport and burial is of critical importance. Using hydrological records of soil erosion and sediment load, and compiled organic carbon (OC) data, estimates of the eroded soils and OC induced by...

The change of primary forest areas into arable land involves the transformation of relief and modification of soils. In this study, we hypothesized that relatively flat loess area was largely transformed after the change of land use due to erosion. The modifications in soil pedons and distribution of soil properties were studied after 185 years of arable land use. Structure of pedons and solum ...

The research aims to study and analyze the physical-mechanical technological properties of eroded soils in Uzbekistan. data on susceptibility water erosion sloping lands is presented. average monthly indicators precipitation over last ten years Uzbekistan are analyzed. results determining moisture, density, hardness soil slopes It has been established that with traditional technology tillage ot...

BACKGROUND Sorption and dissipation of aged metolachlor were characterized in rehabilitated and eroded prairie soils using sequential batch slurry (conventional) and accelerated solvent extraction (ASE). RESULTS In spite of an almost twofold difference in soil organic carbon (OC) content, S-metolachlor sorption coefficients (K(d)) and dissipation rates (DT(50)) were the same in soils from dif...

Unfavourable quantitative and qualitative changes of soil organic matter result from degradation processes, such as water erosion connected with intense arable land use. In order to take adequate preventive action, the proper indicators quality or are urgently needed. particular, tests considering seem be beneficial for monitoring. this paper, we performed fractionation using Tyurin IHSS proced...

Metals in bed-load sediments are multi-source, namely: weathered rocks, metals discharged directly into river, and eroded riparian soils. Contaminated flood plains represent storage system for releasing pollutants to rivers. An essential first step towards modeling this storage is to investigate the relationship. The objective of this study is compare the composition (CaCO3, Cd, Cr, Cu, Fe, Mn,...
