Soil quality decline is one of the main causes of land degradation and is considered to be responsible for 84% of the ever diminishing acreage. Year after year, huge acres of land lost due to soil erosion, contamination and pollution.
Effects of Wind Erosion: The smallest and finest particles are carried by the wind and collected in various areas, creating a build up of loam. Sediment crust degrades and rocks are easily weathered. Sheets of sand traveling close to the ground can degrade crops. It reduces the capacity of the soil to store nutrients.
