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...

Soil aggregate stability and erodibility are the influential factors governing soil resistance to water erosion. The interactions among stability, erodibility, their influencing have not been fully explored. We collected samples from 0–10 cm 10–20 layers in Zhifanggou watershed. Then, major contributors how properties, environmental land use contributed them were explored by using partial least...

There is an abundance of literature on many aspects of soil salinity and sodicity, and the impact of increased salt and sodium on properties, behaviour, management and productivity of soils. However the impact of sodicity on erosion and soil erodibility and sediment transport has received less attention. The aim of this study was to investigate the effects of changing soil salinity and sodicity...

Acid soil covers one third of the world arable lands. Excess Al and H in acid soil are not favorable for most plants. Calcium carbonates and gypsum (CaSO4) are used to improve chemical status of the acid soil. However, application of Ca cation may sometimes enhance dispersion and deteriorate soil physical properties. Presenting study discusses effect of non-ionic polyacrylamide (PAM) applicatio...

Erosion process occurs naturally, shaping the Earth’s surface. Soil loss can cause harmful effects to environment when intensive anthropic activities occur. Mathematical models have been used as effective and less costly alternatives for identifying sites highly prone soil loss, especially at watershed scale. In Brazil, Revised Universal Loss Equation (RUSLE) is one of most commonly prediction ...

of Research Findings Alternative tillage and cropping systems are sought for reducing dust emissions and improving air quality in the Pacific Northwest dryland cropping region. The purpose of this study was to modifiy the conventional rodweeder that would facilitate the armouring of the soil surface with straw and large aggregates otherwise buried below the soil surface. Several modifications w...

Soil piping has been attributed as a potential mechanism of instability of embankments and streambanks. Limited field work has been conducted on quantifying and modeling pipeflow and internal erosion processes in the field with either natural or artificially created soil pipes. This research utilized an innovative constant-head trench system to conduct constant-head soil pipe experiments in two...
