The overall objective of the Circular Economy that Reimagines Corn Agriculture (CERCA) Project is to transform U.S. grain farmland into a net-negative component of a circular bioeconomy and reduce global greenhouse gases through increased uptake and recycling of nitrogen (N) and phosphorus fertilizer. The specific objective is to reduce the N content of the grain by reducing protein from ~8% to ~4%, and reduce the amount of N fertilizer applied. This will also reduce the N content in animal waste when this crop is utilized as a feed.
Researchers will take numerous targeted approaches to reduce protein by examining the N transporters in the plant, N sink in the grain, and protein synthesis machinery in the grain. Researchers will also take several untargeted approaches to reducing grain N by screening natural variation and conducting selection for low N.
