Instead of a 2-year corn and soybean rotation, Dwayne Beck makes a case for a 4-year Corn Belt rotation of corn, corn, soybeans and soybeans. He maintains that his rotation provides more flexibility, lowers weed control costs, offers fewer disease problems, reduces insect concerns and overcomes worries about growing weed resistance.

Allan Brooks knows his stuff.

When you see the number of no-till acres growing significantly in areas outside the Corn Belt, one of the interesting things is the complexity of many rotations. No-tillers in other areas of the country are getting more crops into their rotations and are making them work.

Under the Freedom To Farm Act, Keith Glewen has noticed no-tillers are starting to diversify more with the crops they grow. "When the new government laws were passed, these farmers were concerned about seeing the day when we'll have mountains of grain and that day has come" says the University of Nebraska educator.
