Document Summary

Crop rotations: a planned system of growing different crops in succession on the same land. This ensures they are in different fields every year. Long history since roman empire; romans knew that the legumes and vetch were soil builders so they knew the benefits. Turnip townsend (4 yr) food crop feed crop food crop feed crop. Growing a different crop on different grounds results in better yield. Keeps pests specific to one crop from building up. Different crops place different demands on soil. Avoids consistent depletion of nutrients (different crops have different demands from the soil) Prairie soils that were very nutrient rich and favorable for growth. The soils started off much more productive. The more complex the rotation, the slower the nutrient depletion. But no matter what, agriculture is going to use som. Pasture perennial crops can regenerate the soils. Alternate crop that have different pest complexes.
