Cover cropping
Using cover crops is an effective erosion control measure that also promotes soil health and nutrient management. Cover crops, such as legumes or grasses, are planted during fallow periods or between cash crops to cover the soil surface. These crops help in reducing erosion by protecting the soil from wind and water, improving soil structure, and capturing excess nutrients. Incorporating cover crops into farming practices can significantly contribute to erosion control and water quality protection.
Terracing and contouring
Terracing and contouring are engineering practices that can be implemented to prevent soil erosion on sloping fields. Terraces are earthen structures constructed across the slope, forming a series of level steps to reduce water runoff and increase water infiltration. Contouring involves plowing and shaping the land along the contour lines to slow down water flow and trap sediments. These erosion control measures are particularly effective in hilly or sloping areas, and their implementation helps in safeguarding water sources from sedimentation and potential contamination.
