Vegetation recovery is a promising strategy to mitigate soil loss risk across different landscapes and human disturbance levels. Uncertainties still exist in the impacts of forest restoration on soil ...
Splash erosion in maize crops under conservation management in combination with shallow strip-tillage before sowing
aggregate stability conservation tillage mulch plants cover plants residues silage maize soil protection
2017/6/26
Soil under maize cropping is among the most endangered by erosion. The effect of conservation tillage management on values of splash erosion when using shallow strip tillage before sowing maize was ev...
Effect of row width on splash erosion and throughfall in silage maize crops
erosion growth stage leaf area index plant length precipitation
2017/4/6
Line width is one of the major factors affecting arable soil erosion. The aim of the study was to assess the effects of different row spacing on splash erosion and throughfall in maize crops. Field me...

Evaluation of soil erosion by existing models is needed as an important tool for managerial purposes in designation of proper water and soil conservation techniques. The present study aimed to assess ...
Affectability of splash erosion by polyacrylamide application and rainfall intensity
marl formation polyacrylamide FEL3 rainfall simulator splash erosion
2015/3/5
Splash erosion is recognized as the first stage in a soil erosion process and results from the soil surface bombing by rain drops. At the moment when rain drops conflict with the soil surface, soil pa...
