Over 40% of Moroccos total land area suffers from soil erosion
owing to deforestation, overgrazing by animals and poor planting techniques.
1], application of the high application level of PAM (P4) decreased SL by 22% compared with the control, and the higher input level of PAM was more effective to reduce soil erosion
It said the two towns have vast agricultural lands and agricultural activities, such as plowing and tilling methods, which could induce soil erosion
includes the processes of detachment of soil particles from the soil mass and subsequent transport and deposition of those sediment particles on land surfaces.
The soil erosion
estimation models are focused on the identification and quantification of the erosion processes and the controlling factors, resulting in the sequential erosion models development beginning with the universal erosion equation (USLE) realized by Wischmeier and Smith , followed by a modified equation (MUSLE) for the quantification of the alluvium resulting from erosion following each rainfall realized by Williams , and eventually computerized and more complex equation (RUSLE) developed by Renard et al.
Numerous studies have documented soil erosion
on roadcut and fill embankments (Arnaez et al.
the Department of Interior did not want to lose control over the soil erosion
program (even though funding for the program was slated to end in another year), and many congressional leaders did not want to create yet another government program that would cost money.
Sediment concentrations (g/L) were calculated from the dried residues and the runoff volumes for each of the treatments and were used to calculate soil erosion
Keywords: CORINE, Rawal watershed, risk maps, soil erosion
, soil loss
in watershed areas and the subsequent deposition in rivers, lakes and reservoirs are of great concern for two reasons.
Baghdad (NINA) -- Technical Agriculture Ministry Undersecretary, Mahdi Dhamad Al Qaisi, discussed with a specialized delegation from the Ministry of Environment means of handling the desertification phenomenon and soil erosion
At Pendleton, Williams, Long, and soil scientists Hero Gollany and Stewart Wuest compared runoff, soil erosion
, and crop yields in a conventional, intensively tilled winter wheat-fallow system and a no-till 4-year cropping rotation system.
