New ISU Research: 3-Year Crop Rotation Works Best

Des Moines, Iowa — September 13, 2011

Iowa farmers have long used a two-crop rotation to keep the yields up in their fields, but new research at Iowa State University (ISU) indicates they could increase their yields even more by using a third crop in the rotation cycle.

ISU agronomist Matt Liebman says an example is the boost soybeans get from using three crops instead of two.
 "We've seen a gain from 42 bushels an acre in the two-year rotation up to 54 and 55 bushels an acre in the three-year and the four-year rotations."

Liebman says rotation can reduce the impact of "soybean sudden death syndrome (SDS)" and increase weed seed predators. 
"And we get outstanding weed control; that's important now, because we are starting to see resistance to glyphosate."

He says the three-year plan is a corn-soybean-oat and red clover rotation. Essentially, he says, it allows a farmer to "grow his own nitrogen" and reduce having to purchase inputs, which leads to higher profits.

  • NORTHEY COMMENTS ON IOWA CROPS - October 11

    “The dry weather last week helped crops continue to dry down and allowed nearly half of the state’s soybeans to be harvested.  Unfortunately, fire does remain a risk as the dry weather persists, so farmers should continue to take extra care while working in their fields,” Northey said.  “Harvest remains slightly ahead of the five-year average and will likely continue to advance rapidly if conditions remain dry.”

    As harvest begins around the state, farmers are encouraged to be aware of the potential for development of molds and fungus in corn. Recent warnings by Iowa State University (ISU) Extension and Outreach’s Integrated Crop Management (ICM) staff about hail-damaged corn in northwest Iowa help draw attention to the issue, according to ISU Extension swine program specialist Matt Swantek.
