Location: Soil, Water & Air Resources Research
Project Number: 5030-11610-003-000-D
Project Type: In-House Appropriated
Start Date: Nov 3, 2015
End Date: Oct 8, 2018
Objective:
Objective 1: Evaluate the impact of temperature and soil water stress on germplasm of corn, soybean, and wheat.
Objective 2: Quantify the interactions of water and temperature stresses on energy and carbon exchanges in corn and soybean fields under different management systems.
Objective 3: Describe the relationships between ground-based and satellite observed water use and net primary productivity across the Upper Midwest and California.
Objective 4: Evaluate agroforestry practice effects on local microclimate, and on crop and forage production, carbon sequestration, and greenhouse gas production.
Approach:
Development of an enhanced understanding of the impact of temperature and moisture stress on corn, soybean, wheat, and forage phenology and productivity to provide information to incorporate into crop simulation models. Detailed analyses of the impact of different management systems (controlled drainage vs uncontrolled drainage, unsheltered vs sheltered crops) on the energy exchanges and crop productivity of cropping and agroforestry systems will be undertaken. Development of water use and net primary and gross primary productivity maps for the upper Midwest to compare to county level yield maps and evaluation of improved water management techniques. Refinement of crop growth simulation models to improve the understanding of the interactions of carbon-temperature-water under variable conditions. Improved understanding of complex interactions of variable environments on maize phenology, phenotypes, and production across North America.
