Crop rotation

The use of a crop rotation sequence, rather than continual successive plantings of the same crop can play a role in reducing soil erosion as well as provide other benefits (vary the rooting depth and thereby moisture and nutrient uptake, restore soil structure, break pest and disease cycles, help maintain soil fertility, Hudson 1981). When land is used repeatedly for cultivating relatively open row crops (i.e. corn, beans, tobacco, etc.), a rotation with a denser green manure or forage crop can reduce erosion because of the ground cover provided. Also the maintenance of soil fertility and structure will allow the next planting of the more open crop to grow more vigorously and develop better root systems, thereby helping reduce some soil loss. Generally, however, on sloping lands (5-10% +), crop rotations alone will have little effect on erosion, and should be used in combination with other techniques.
