A method for using WEPS to map wind erosion risk of Alberta soils
Alberta has 27 million hectares of agricultural land, a significant portion of which is at risk to wind erosion. Combining recently completed provincial digital soils maps (Agricultural Region of Alberta Soil Inventory Database—AGRASID) with geographically referenced spatial weather data and land management descriptions (crop rotations plus cultivation practice) provided an opportunity to evalu...
متن کاملEffects of reduced tillage on soil surface properties affecting wind erosion in semiarid fallow lands of Central Aragón
In Central Aragón (NE Spain), where strong and dry winds are frequent all year round, fallow lands are susceptible to wind erosion due to insufficient crop residues on the surface and loose, finely divided soils by multiple tillage operations. Effects of conventional tillage (CT — mouldboard ploughing followed by a compacting roller) and reduced tillage (RT — chisel ploughing) on soil surface p...
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...
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 کاملThe Influence of Soil Properties on the Wind Erosion Rate at Different Regions of Kerman Province
Wind erosion is known as one of the most important land degradation aspects, particularly in arid and semi-arid regions. Soil properties, by affecting soil erodibility, can control the wind erosion rate. The aim of this study was to attribute the soil physical and chemical properties to the wind erosion rate for the purpose of determining the most important property. To this aim, wind erosion r...
