What is the main crop rotation of the Midwest?
Cropping System 2: Corn-soybeans This moderate-input, two-crop rotation is prevalent in the upper Midwest. The two-crop rotation breaks up some pest cycles and reduces the need for nitrogen fertilizer in corn. Chemical as well as occasional mechanical weed control is used on corn.
What is crop rotation why it is important?
Crop rotation involves planting a sequence of different kind of crops in a location over a number of seasons (Figure 1). Rotating crops helps maintain or improve soil health and maintain or increase the productivity of the farm over time.
What is another name for crop rotation?
ley farming
The four-field crop rotation became a key development in the British Agricultural Revolution. The rotation between arable and ley is sometimes called ley farming.
How do farmers use crop rotation?
Crop rotation helps return nutrients to the soil without synthetic inputs. The practice also works to interrupt pest and disease cycles, improve soil health by increasing biomass from different crops’ root structures, and increase biodiversity on the farm.
What is crop rotation and why is it important?
What is crop rotation? Crop rotation is the practice of planting different crops sequentially on the same plot of land to improve soil health, optimize nutrients in the soil, and combat pest and weed pressure. For example, say a farmer has planted a field of corn.
When did crop rotation start in the south?
In modern times, crop rotation was reintroduced in the American South by George Washington Carver in the late nineteenth century. He described what crop rotation is and suggested alternating cotton, which depleted soil nutrients, with crops like peanuts and peas, which enrich the soil by adding nitrogen.
How is crop rotation an alternative to monoculture?
He described what crop rotation is and suggested alternating cotton, which depleted soil nutrients, with crops like peanuts and peas, which enrich the soil by adding nitrogen. Crop rotation is now seen as an alternative to the modern practice of monoculture, which demands heavy inputs of chemical fertilizer and pesticides.
Why do farmers rotate corn and soybean fields?
For example, soybeans are often affected by nematodes. Nematodes won’t feed on corn like they do with soybeans. By rotating corn and soybean fields, farmers can minimize the nematode population that might affect their soybean yield. Planting various crops year after year can also benefit soil tilth.

How often do you rotate corn and soybeans?
In the U.S. Midwest, it is common for grain growers to practice a two-year crop rotation by alternating between corn and soybeans in a given field each year. In order to gain maximum benefits from crop rotation, you need a rotation sequence that is longer than two years.
