Project Number: 5030-11610-006-004-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Jul 1, 2021
End Date: Jun 30, 2024
1. Evaluate interactions among nitrogen, carbon, soil water, and crop growth response across a range of soil types in a production field. 2. Evaluate field scale decision support system for nitrogen and crop management.
Field scale studies will be developed to evaluate nitrogen response to varying soil water regimes across a production field and the carbon dynamics in response to nitrogen management. Corn-soybean rotations will be evaluated over three growing seasons. Water, CO2, nitrogen, and light exchanges will be measured at several field locations within the field.
