Crop Rotation could be thee most important cropland practice there is. A tremendous amount of tillage and chemicals is used each year trying to battle weed, insects and disease.

Crop rotation reduces weed, insect and disease problems by removing the crop that favors the problems for a year or two. Planting a fall seeded crop as apposed to a spring seeded might help control early summer annual weeds.

All of these problems are sometimes attacked by increased tillage. The more tillage the less crop cover. This leads to more soil erosion.

A crop rotation should include at least one legume (a nitrogen fixing plant) such as soybeans or red clover to gain maximum benefits.
