Study: Crop Rotation Can Save Money

A study conducted by Iowa State University shows that crop rotation can reduce fossil fuels and make soil healthier in the long term. The study compared the effects of a four and five-year rotation of corn, soybeans, oats and alfalfa. A five-year rotation would create greater energy savings and healthier soil, while a four-year rotation could be a more attractive option when energy prices go up. (AgWeb). Learn more.
