Project Number: 3625-11610-001-17
Project Type: Specific Cooperative Agreement

Start Date: Sep 12, 2011
End Date: Jun 30, 2013

Objective:
1) Evaluate interactions among nitrogen, carbon, soil water, and crop growth response across a range of soil types in a production field; and 2) Evaluate field scale decision support system for nitrogen and crop management.

Approach:
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.
