Crop rotations are planned sequences of different crops on the
same field over time. Rotating crops provides productivity
benefits by improving soil nutrient levels and breaking crop
pest cycles. Farmers may also choose to rotate crops to reduce
their production risk through diversification or to manage
scarce resources, such as labor, during planting and harvesting
time. One indication of how prevalent crop rotations are in U.S.
production is how relatively rare it is for farms to
continuously produce the same crop from year to year on the same
field. For corn, soybean, and wheat, between 84 and 92% of
acreage involves some sort of rotation. This chart is found in
the March 2013 Amber Waves finding, While Crop Rotations Are
Common, Cover Crops Remain Rare.               You might also
