Grass cropping in the rotation and the use of no-till seeding appear to be important components for developing sustainable cropping systems. Grass cropping and no-till seeding improve soil organic matter content, increase the soil microbial biomass, increase earthworm numbers, likely cause a buildup of fungivorous microarthropods and nematodes, and greatly increases the resistance of soil to er...

Quantification of soil aggregation and erodibility from easily measurable characteristics have been done by using pedo-transfer functions (PTFs) PTFs developed were compared statistical machine learning techniques for the kandi region Punjab. Dataset 1, having six basic properties, was used estimation mean weight diameter (MWD) (K), prediction an artificial neural network (ANN) slightly better ...

Slope erosion in the black soil region of Northeast China is complex and specific. In order to effectively control protect scarce resources, it necessary reveal law influence basic units structure on its process. This paper used three treatments Le Bissonnais (LB) method determine aggregate stability parameters erodibility K values based particle size composition. By establishing a mathematical...

Soil erosion involves detachment and transport of soil particles from top soil layers, degrading soil quality and reducing the productivity of affected lands. Soil eroded from the upland catchment causes depletion of fertile agricultural land and the resulting sediment deposited at the river networks creates river morphological change and reservoir sedimentation problems. However, land managers...

Assessment of soil erosion and sediment yield in furrow irrigation is limited in Samaru-Zaria. Data was collected in 2009 and 2010 and was used to develop a dimensionless model for predicting furrow irrigation-induced erosion (FIIE) using the dimensional analyses approach considering stream size, furrow length, furrow width, soil infiltration rate, hydraulic shear stress, soil erodibility, and ...

mulching is one of the methods of sand movement control to prepare condition for permanent fixation. oil mulches have been used in iran. because of high cost and negative environmental impacts of oil mulches, changes in mulches type and mulching methods is vital. therefore, for the first time in iran, different combinations of cement and lime were examined as stabilizer. sandy soil from the yaz...

Wind erosion is a broad-scale process in inland Australia. When conditions are conducive to wind erosion, dust storms can entrain fine sediment over large areas of the continent, however closer examination indicates that the dust source areas are often spatially discrete. The fine sediment entrained from these sources, is transported as dust plumes, which may coalesce at some point downwind. Wh...

Redistribution of soil, nutrients, and contaminants is often driven by wind erosion in semiarid shrublands. Wind erosion depends on wind velocity (particularly during episodic, high-velocity winds) and on vegetation, which is generally sparse and spatially heterogeneous in semiarid ecosystems. Further, the vegetation cover can be rapidly and greatly altered due to disturbances, particularly fir...

The rock mass erosion of dam spillways, a phenomenon involving the interaction between hydraulic load water and capability to resist its destruction, remains critical safety issue. resistance can be estimated through several erodibility indices, including those Kirsten, Pells or Bollaert. Several indices have been developed link parameters water, i.e., applied on mass. use average flow velocity...

Combining natural saltmarsh habitats with conventional barriers can provide a sustainable and cost-effective alternative for fully engineered flood protection, provided that minimal salt marsh width be guaranteed long period. Hence, it is essential to understand both the key factors management options driving lateral erodibility/stability of marshes. We aimed determine how (i.e. grazing by larg...
