Crop Rotations Forage crops are a component in many conservation farming systems. Forages can be grown on poorer soils or steep slopes not suitable for other crops, or used in rotations to build organic matter or break disease cycles. Forage cover protects the soil from erosion, and the fibrous roots hold the soil in place. As a perennial crop or plowdown, forages add organic matter and improve soil quality and structure. Improved soil structure allows the soil to absorb more water which reduces runoff and erosion.
Forage crops protect and improve the soil.
Legumes protect the soil and add nitrogen and organic matter. Crop rotations for erosion control alternate forages with cereals and oilseeds or legumes. A well-planned rotation will improve soil quality and reduce erosion. Legumes in the rotation also add nitrogen and improve soil fertility. In drier areas, forages are harder to establish and may deplete moisture in a short-term rotation.
