By definition, soil salinization is "the process by which a nonsaline soil becomes saline, as by the irrigation of land with brackish water," according to Dictionary.com. The dissolved salts in irrigation water are the p... More »

Wind causes erosion in one of three ways: suspension, saltation or surface creep. There are many problems that arise from wind erosion, including air pollution, soil loss and dryness. Soil tillage, crop barriers and crop... More »

Wind erosion happens when pieces of the Earth are worn away by strong winds over time, and water erosion happens when moving water such as ocean waves wear away rock instead of seeping into the ground. Water is a more po... More »

Contour plowing conserves soil by following the lay of the land and creating ridges that form a water break to prevent soil erosion. Furrows that do not follow the lay of the land cause rapid runoff during rainfall by fo... More »
