Erosion control on forest soils with vegetation, under global change
Soil erosion is a complex phenomenon which combines the deterioration of their surface layers and the movement of the eroded materials that make it up. It is a constant issue for foresters, in particular in the management of new or restored forests. In metropolitan France, we spontaneously think about the restoration of mountain terrains (RTM), implemented from 1860 to stabilise degraded mounta...
متن کاملModeling of piping erosion in loess soils
Extended abstract Introduction Piping erosion is one of the common water erosions usually occurs in soil with low infiltration and soluble minerals that finally changes landscape. Different factors control its occurrence and development. To predict piping occurrence/hazard through modeling, effective factors should be prioritized and considered as inputs of the model. The present study...
متن کاملErosion Control in Furrow Irrigation Using Polyacrylamide
Currently gravity irrigation remains the most widely used in agricultural areas and 90 percent of plantings, the water is applied to the plots by gravity. One of the main problems with these systems is erosion, which is a by product of the erosive forces of water over the row, which brings soil loss and therefore decreases in crop yield. Erosion is the removal of surface soil material caused by...
متن کاملRemoval of Microcystis aeruginosa using cationic starch modified soils.
A cheap and biodegradable modifier, cationic starch (CS), was used to turn local soils into effective flocculants for Microcystis aeruginosa (M. aeruginosa) removal. The isoelectric point of soil particles was remarkably increased from pH 0.5 to 11.8 after modification with CS, which made CS modified soil particles positively charged and obtain algal flocculation ability. At the soil concentrat...
متن کاملSoil property effects on wind erosion of organic soils
Histosols (also known as organic soils, mucks, or peats) are soils that are dominated by organic matter (OM > 20%) in half or more of the upper 80 cm. Forty two states have a total of 21 million ha of Histosols in the United States. These soils, when intensively cropped, are subject to wind erosion resulting in loss of crop productivity and degradation of soil, air, and water quality. Estimatin...
