Research Project: Soil and Gas Flux Response to Improved Management in Cold, Semiarid Agroecosystems

Location: Northern Great Plains Research Laboratory

Project Number: 5445-11120-002-00
Project Type: Appropriated

Start Date: Jun 20, 2011
End Date: Oct 31, 2015

Objective:
OBJECTIVE 1: Develop management strategies to decrease net greenhouse gas emissions from cold, semiarid agroecosystems, as a contributor to the ARS GRACEnet project. OBJECTIVE 2: Develop soil management guidelines to improve soil biophysical properties needed for sustainable production.

Approach:
Concurrent trends of increased demand for agricultural products, increasingly scarce nonrenewable resources, and accelerating climate change have underscored the need for new and innovative agroecosystems that are resilient, highly productive, effectively utilize renewable resources, and minimize damage to the environment. Determining the relative sustainability of new and innovative agroecosystems requires a detailed understanding of management effects on emerging ecosystem services. Given this context, the goal of this project is to improve understanding of management impacts on greenhouse gas mitigation, carbon storage, and soil biological function. Over a time period of approximately five years, research activities will 1) develop management strategies to decrease net greenhouse gas emissions from cold, semiarid agroecosystems (Objective 1), and develop soil management guidelines to improve soil biophysical properties needed for sustainable production (Objective 2). Approaches to conduct these research activities will include field, laboratory, and greenhouse experiments. Anticipated products from this research include peer-reviewed publications, popular press articles, and web pages. Collectively, these products will serve a broad range of clientele (e.g., agricultural producers, personnel from public and private sector organizations, and scientists), and will contribute to an overall outcome of increased understanding of agroecosystem effects on emerging ecosystem services, with the intent of improving agricultural sustainability.
