Accelerated erosion is the type that will be covered in most depth. It includes such problems as The action of wind on exposed sediments and friable rock formations causes erosion (abrasion) and entrainment of sediment and soil. Eolian action also forms and shapes sand dunes, yardangs (streamlined bedrock hills) and other landforms. Subsurface deposits and roots are commonly exposed by wind erosion. Wind can also reduce vegetation cover in wadis and depressions, scattering the remains of vegetation in interfluves. Stone pavements may result from the deflation
Soil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. Soil deterioration and low quality of water due to erosion and run off has often become a severe problem around the world. Many times the problems become so severe that the land can no longer be cultivated and is abandoned. The key to minimizing soil erosion and saving the farm lands is the farmer himself. Ultimately, he is the one who must reduce the level at which erosion sediments are dislodged from his cropland. This program will discuss the erosion process, its effects on crops and the environment, and the Best Management Practices that can be implemented to limit or contain soil movement from the land.
A small child stares out the window watching the rainfall to the ground. She stares in amazement as the water soaks in to the freshly tilled earth, and then slowly begins to pool. The longer she sits the pool grows and grows until a small stream begins to flow across the yard. She closes her eyes and imagines sinking her dainty toes into the warm, soft mud. Sitting next to her is her anxious younger brother who eagerly awaits the stopping of the rainfall, for he knows that when the rain stops the ground comes alive!
