Rotation of crops is a very wise agricultural practice.
Some reasons to practice crop rotation are:
Most diseases reoccur due to pathogen buildup. The most effective resistance is using crop rotation and other management practices. Disease resistance should be a priority in selecting hybrids or varieties if you know that a certain disease is or has been a problem and has the potential to reoccur. However, there are a few disease that do survive the crop rotation such as: rust, Stewarts wilt of corn, and yellow dwarf in wheat and oats. Some of these diseases can cause complete crop failure in the non-rotated field.
Increased yields of crops:
Typically in Ohio, a three-year crop rotation of corn, wheat and soybeans is the most common. According to Ohioline information sheets, this three-year rotation appears to be the best option to achieve a sustained yield for all three crops. The increased yields go hand-in-hand with the previous two topics.
