The U.S. Department of Agriculture (USDA) is investing $10 million in a new initiative to sample, measure, and monitor soil carbon on Conservation Reserve Program (CRP) acres to better quantify the climate outcomes of the program. CRP is an important tool in the Nation’s fight to reduce the worst impacts of climate change facing our farmers, ranchers, and foresters. This initiative will begin implementation in fall 2021 with three partners. Today’s announcement is part of a broader, long-term soil carbon monitoring effort across agricultural lands that supports USDA’s commitment to deliver climate solutions to agricultural producers and rural America through voluntary, incentive-based solutions.    

These models include the Daily Century Model, or DayCent, which simulates the movement of carbon and nitrogen through agricultural systems and informs the National Greenhouse Gas Inventory. Data will also be used to strengthen the COMET-Farm and COMET-Planner tools, which enable producers to evaluate potential carbon sequestration and greenhouse gas emission reductions based on specific management scenarios.    

USDA partners will conduct soil carbon sampling on three categories of CRP practice types: perennial grass, trees, and wetlands.    

Perennial grasses: In consultation with USDA, Michigan State University will sample and measure soil carbon and bulk density of CRP grasslands (including native grass plantings, rangelands, and pollinator habitat plantings) at an estimated 600 sites across the U.S. with a focus in the central states during this five-year project. This information will be used to model and compare the climate benefits of CRP. Partners include the University of Wisconsin-Madison, the University of Arkansas at Pine Bluff, Deveron, an agriculture technology company, and Woods End Laboratories.    

Trees: Mississippi State University will partner with Alabama A&M University to collect above and below ground data at 162 sites across seven states documenting CRP-related benefits to soil and atmospheric carbon levels. Information will help further calibrate the DayCent model. This five-year project will focus within the Mississippi Delta and Southeast states.          

Wetlands: Ducks Unlimited and its partners will collect data on carbon stocks in wetland soils as well as vegetation carbon levels at 250 wetland sites across a 15-state area in the central U.S. Data will support the DayCent and additional modeling. Partners for this five-year project include: Migratory Bird Joint Venture, Intertribal Research and Resource Center at United Tribes Technical College, Clemson University, Kenyon College, Lincoln University, Pennsylvania State University, the University of Missouri, and the University of Texas at Austin.   

  CRP Monitoring, Assessment, and Evaluation Projects    

These three Climate Change Mitigation Assessment Initiative projects are funded through FSA’s program to work with partners to identify Monitoring, Assessment and Evaluation (MAE) projects to quantify CRP environmental benefits to water quality and quantity, wildlife, and rural economies.   

Applications for projects were welcome from all organizations, including public, private, nonprofit institutions, and educational institutions including historically Black colleges and universities, Tribal colleges and universities and Hispanic-serving institutions or organizations.

    About the Conservation Reserve Program    

CRP is one of the world’s largest voluntary conservation programs, with an established track record of preserving topsoil, sequestering carbon, reducing nitrogen runoff and providing healthy habitat for wildlife.    

In exchange for a yearly rental payment, agricultural producers enrolled in the program agree to remove environmentally sensitive land from production and plant species that will improve environmental health and quality. In general, land is enrolled in CRP for 10 to 15 years, with the option of re-enrollment. FSA offers multiple CRP signups, including the general signup and continuous signup, as well as Grassland CRP and pilot programs focused on soil health and clean water. In 2021, producers and landowners enrolled more than 5.3 million acres in CRP signups, surpassing USDA’s 4-million-acre goal.   

Earlier this year, USDA announced updates to CRP including higher payment rates, new incentives for environmental practices, and a more targeted focus on the program’s role in climate change mitigation. This included a new Climate-Smart Practice Incentive for CRP general and continuous signups that aims to increase carbon sequestration and reduce greenhouse gas emissions. Climate-Smart CRP practices include establishment of trees and permanent grasses, development of wildlife habitat, and wetland restoration.

   More Information   

Under the Biden-Harris Administration, USDA is engaged in a whole-of-government effort to combat the climate crisis and conserve and protect our nation’s lands, biodiversity, and natural resources including our soil, air, and water. Through conservation practices and partnerships, USDA aims to enhance economic growth and create new streams of income for farmers, ranchers and private foresters. Successfully meeting these challenges will require USDA and our agencies to pursue a coordinated approach alongside USDA stakeholders, including State, local, and Tribal governments.    

USDA touches the lives of all Americans each day in so many positive ways. In the Biden-Harris Administration, USDA is transforming America’s food system with a greater focus on more resilient local and regional food production, fairer markets for all producers, ensuring access to healthy and nutritious food in all communities, building new markets and streams of income for farmers and other producers using climate smart food and forestry practices, making historic investments in infrastructure and clean energy capabilities in rural America, and committing to equity across the Department by removing systemic barriers and building a workforce more representative of America.
