University of Arkansas Tracks GHG Emissions from Poultry Feed Crops
Most greenhouse gas (GHG) emissions from commercial poultry operations are related to feed production, and methods to reduce these emissions are the subject of a grant from the U.S. Department of Environment. Agriculture (USDA) at the System of Agriculture Division of the University of Arkansas.
Arkanasas State harvested more than 3 million acres of soybeans and 830,000 acres of grain corn in 2021, according to the 2022 Arkansas Agricultural Profile.
During this time, a Life cycle analysis 2020 found that animal feed production contributed about 72% of the GHG emissions associated with broiler production.
The Arkansas Agricultural Experiment Station, the research arm of the Division of Agriculture, will perform measurements of GHG emissions on farms that grow corn and soybeans. This data will inform subsequent assessments to determine which is the more climate-smart practice: conventional tillage or conservation tillage.
The emissions measurement work will be led by Kris Brye, university professor of applied soil physics and soil science, Arkansas Agricultural Experiment Station.
The Agriculture Division will also assess local market opportunities for direct sale and tracking of grain to broiler operations.
The research is supported by the USDA Climate-SMART Commodity Program. The university team will be funded for at least three years to demonstrate the viability of growing more environmentally friendly grains for sale to poultry feeding operations.
Journeyman Education Program
Project support includes funds to create a complementary education program with postdoctoral and graduate students, as well as a Climate-SMART instructor and a technician from the Division’s Crop, Soil and Environmental Sciences Department. of farming.
Other project partners include Mississippi State University, Alcorn State University in Mississippi, Southern Ag Services Inc. and Conservation Solutions LLC.
