Research Project: NUTRIENT AND RESIDUE MANAGEMENT IN INTENSIVE CROPPING SYSTEMS

Location: Agroecosystem Management Research

Project Number: 5440-11210-001-03
Project Type: Trust

Start Date: Oct 01, 2008
End Date: Sep 30, 2011

Objective:
The objectives of this cooperative research project are to determine the role of soil microorganisms in crop nutrient utilization and develop relay cropping and double cropping management practices for maintaining soil function in fields where crop residue is harvested for forage or as a biofuel feedstock.

Approach:
Field-scale studies will be conducted in cooperation with producers, agencies (federal, state, and local), agribusiness interests, and University colleagues to address issues related to understanding and managing soil microbial processes affecting nutrient availability, plant growth, and soil organic matter dynamics. A team approach will be used to evaluate processes involving plant, residue, and soil components of the agroecosystem. Management and decision aids for producers and land managers will be developed for nutrient management, tillage, and residue retention rates. Research will involve stakeholder input to insure critical issues are addressed and products and technologies are developed in a timely manner. University employees (UNL) will provide some of the labor depending on the nature of the study. Projects are jointly planned with University scientists and producers.
