Using fertilizer efficiently is vital for managing agroecosystems sustainably. It makes the most of crop productivity while protecting the environment. As agriculture has intensified, the use of synthetic nitrogen (N) fertilizers has increased.
The warming of the earth’s climate and an increasing global population is presenting enormous challenges for the agricultural industry to increase food production. More frequent extreme weather events caused by climate change, such as drought, are problematic for the Northern Corn Belt, where simple two-crop rotations of corn and soybean are common.
