Crop rotation is a component of crop production and an implement for farm management as it balances agronomy and economic market realities. From an agronomic perspective, crop rotation can increase nutrient cycling and nutrient use efficiency, decrease plant diseases and insect pests, assist in managing weeds, reduce soil erosion and increase soil health. A common rotational system in the Corn Belt is corn followed by soybean for a two-year rotational program. Research at Iowa State University on extended multi-year rotations of three to four years, found that net economic returns did not differ among the cropping systems, corn and soybean yield potential increased, soil health improved, soil erosion decreased, herbicide and nitrogen (N) fertilizer use decreased, and some plant diseases were reduced.
