Wisconsin farmers are learning about a long-term study into corn and soybean yields using different crop rotation schemes.
University of Wisconsin agronomy professor Joe Lauer says their research shows higher corn yields after alfalfa. “During that time, you can get much better, longer-lasting, if you will, root channels for example. You can get better soil aggregation.”
And, he says that one year of soybeans will yield between
three and five percent more.
