Question

Many farmers practice "crop rotation" by planting a field with corn one year and soybeans the next. why might they do this?

Answer 1

The reason that they do this because rotating crops has the capability of keeping the nitrogen from being depleted in the soil as nitrogen fixing bacteria are likely to be found in the nodules of the roots of the soybeans and not on the corn’s roots that makes soybeans the next after the corn is planted first.
