Research Project: Precision Zonal Management Systems for Resilient Cereal Yields under Variable Climates

Location: Soil and Water Management Research

Project Number: 5062-12000-008-01
Project Type: Reimbursable

Start Date: Apr 01, 2011
End Date: Mar 31, 2016

Our objective in this project is to advance understanding of physical processes and plant-soil microbial interactions that are the basis of functional differences between active-turnover and soil-building zones biology, and to examine the implications of these processes for resilience and adaptation to variable climates in cereal production systems.

We hypothesize that, relative to uniform management systems, precision zonal management systems change both physical and microbiological processes so as to substantially increase N- and water-use efficiency, improve soil C storage, and maintain high yield potential under more variable climate conditions. Our long-term goal is to understand the functional agroecology of precision zonal management systems that build upon current precision farming approaches (e.g. GPS guidance, variable rate fertilizer/agrochemical applications) to create highly resilient and sustainable field crop production systems.
