Dryland Cropping

United States Department of Agriculture (USDA) Research, Education & Economics Information System (REEIS)

Titre : SOIL MANAGEMENT SYSTEMS FOR DRYLAND AND IRRIGATED CROPPING SYSTEMS

Identification : 5440-12210-050-00

Pays : Etats Unis

Durée : Oct 01, 2006 à Sep 30, 2011

Objectif
Objective 1 : Determine the role of spatial variability in affecting management outcomes in dryland and irrigated systems. a. Develop sensors for in-season nutrient management. b. Determine management zones for efficient use of inputs. c. Residue management to maintain or enhance critical soil functions.
Objective 2 : Improve understanding of N and C dynamics in cropping and tillage systems commonly used in the Western Corn Belt and Central Great Plains. a. N index - Assist NRCS efforts to develop a N index for identifying BMP’s that minimize N losses in runoff and leaching. b. Develop an algorithm for in-season N management. c. Soil C dynamics to enhance C sequestration.
Objective 3 : Implement and expand the Soil Management Assessment Framework (SMAF) a. Develop additional scoring curves for the SMAF. b. Implement the SMAF.
Objective 4 : Determine the impact residue removal for biofuel production has on the soil resource.
