Research Project: Determine Greenhouse Gas (Ghg) Emissions from Diverse Grazing Systems in the Southern Great Plains

Location: Forage and Livestock Production Research

Project Number: 3070-21610-002-06-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Apr 1, 2016
End Date: Mar 31, 2021

Objective:
Monitoring greenhouse gas (GHG) emissions from diverse grazing systems in the Southern Great Plains

Approach:
Beef produced on pasture and rangeland forages and dual-purpose winter wheat in the Southern Plains (SP: Texas, Oklahoma, and Kansas) provides a significant portion of the nation’s red meat while contributing greatly to farm income in the region. Knowledge on how cattle grazing and associated management practices affect GHG (CO2, CH4, and N2O) emissions and soil nutrient cycling in these systems will help to identify sustainable management practices. The cooperative team comprising researchers from Forage and Livestock Production Research Unit and Oklahoma State University will identify diverse grazing systems in and around Grazinglands Research Laboratory and measure GHG emissions using static chamber method. In addition, soil samples will be taken for nutrient analysis. Analysis will be done on the effects of tillage, crop rotation, nitrogen fertilization, and grazing intensity on GHG emissions.
