AgTech : Rotation of Crop boosts soil microbes which benefits plant growth

New research from the University of New Hampshire shows that crop rotations, in isolation from other management factors, can increase the functions performed by soil microbial communities that benefit plant growth.

Researchers tested five combinations of three crops - soy, wheat, and corn - and two cover crops - red clover and rye. They also planted a crop of only corn, while minimizing the effects of other management practices such as variable fertilizer and pesticide inputs that interfere with the crop rotation effect.

It has been seen that a 33 percent increase in soil carbon by increasing rotational diversity. An indication of soil organic matter, the carbon content of soil is a major factor in its overall health and improves the physical properties of soil. Researchers also found that as crop diversity increased, so did total nitrogen concentrations, a sign of soil fertility.

Increasing plant biodiversity by crop rotation is a powerful tool for farmers to increase soil quality. Even increasing rotation by one or two crops, especially if cover crops are used, will improve soil physical, chemical, and biological processes that help regulate yields and environmental quality.
