Papers Published by the Journal of Soil and Water Conservation Provide Evidence that USDA Conservation Practices Work
Research is showing that conservation practices are working to reduce runoff, improve soil quality, and mitigate contaminants in small watersheds across the country, according to USDA’s scientific findings published in the Journal of Soil and Water Conservation. USDA’s Natural Resources Conservation Service (NRCS), Agricultural Research Service (ARS) and other USDA agencies collaborated with universities and organizations to complete the water-quality studies featured in the journal through USDA’s Conservation Effects Assessment Project (CEAP). “The scientific findings in this special issue of the Journal of Soil and Water Conservation show that voluntary conservation programs work,” said Jerry Raynor, NRCS state conservationist in Indiana. “The conservation practices installed through these programs improve water and soil quality, and these scientific studies have also taught us how to improve our programs in the future.” “ARS is home to some of the greatest scientific minds in agriculture. This special issue is a result of their authoritative and revolutionary work and our collaboration with partners over the years,” said ARS Administrator Chavonda Jacobs-Young. “Science-based research and innovation makes the difference in achieving positive outcomes such as these.”
The issue includes 15 peer-reviewed research papers and two feature articles, one analyzing results from watershed studies spanning 15 years of CEAP assessments in watersheds. The impacts measured include reduction of sediment and nutrients lost in runoff, improvement in soil quality and improved understanding of conservation practices to mitigate contaminant losses. Practices were assessed at plot, field, edge-of-field and watershed scales and included drainage management, conservation tillage, cover crops, buffers, irrigation, nutrient management, water management and Conservation Reserve Program (CRP) practices.
Two papers that hit home in Indiana are the Mississippi River Basin and Western Lake Erie Basin studies. In the Central Mississippi River Basin, research found that combining no-till and cover crop practices reduced sediment losses by 87% and nitrate losses by 57% on a monitored field due to changes in soil moisture, timing of nitrogen applications and use of cover crops (Baffaut et al. 2020).
In the Western Lake Erie Basin, edge-of-field monitoring revealed that subsurface placement of fertilizer in tile-drained fields reduced dissolved phosphorus losses by 66% (Williams et al. 2018). In addition, an innovative conservation practice was developed to treat contaminant losses from drainage water – replacing tile risers with blind inlets. This new practice reduced sediment losses by about 78% (Smith and Livingston 2013), total phosphorous losses by 66% and dissolved phosphorus losses by 50% (Feyereisen et al, 2015).
The USDA spends about $6 billion per year on agricultural conservation programs to help producers and landowners implement suitable conservation practices and systems on their land. In 2003, NRCS, ARS and other agencies created CEAP to quantify the environmental effects of conservation practices and programs and to develop the science base to effectively manage the agricultural landscape for environmental quality.

Community Compost Funding Opportunity USDA Announces Cooperative Agreements for Community Compost and Food Waste Reduction The U.S. Department of Agriculture (USDA) announced the availability of $900,000 for local governments to host a Community Compost and Food Waste Reduction (CCFWR) pilot project for fiscal year (FY) 2020. The cooperative agreements will support projects that develop and test strategies for planning and implementing municipal compost plans and food waste reduction plans. The agreements are offered through USDA’s Office of Urban Agriculture and Innovative Production.
“Food waste shouldn’t end up in landfills when options like food recovery and composting are available,” Under Secretary for Farm Production and Conservation Bill Northey said. “Such options not only benefit communities and the environment, they can also provide farmers and urban gardeners with exceptional, nutrient dense planting material.”
“We are tapping into the creativity of communities across the nation to rethink the lifecycle of food in ways that minimize waste and maximize use.” said Under Secretary for Marketing and Regulatory Programs Greg Ibach. “We look forward to highlighting the innovative practices of selected pilot projects.”
USDA will accept applications on Grants.gov until midnight June 26, 2020. Projects should span two years with a start date of October 1, 2020 and completion date of September 29, 2022.
Cooperative agreements support projects led by local governments that: 1) generate compost; 2) increase access to compost for agricultural producers; 3) reduce reliance on, and limit the use of, fertilizer; 4) improve soil quality; 5) encourage waste management and permaculture business development; 6) increase rainwater absorption; 7) reduce municipal food waste; and 8) divert food waste from landfills. USDA’s Natural Resources Conservation Service will provide assistance for conservation related activities.
Priority will be given to projects that anticipate or demonstrate economic benefits; incorporate plans to make compost easily accessible to farmers, including community gardeners; integrate other food waste strategies, including food recovery efforts; and collaborate with multiple partners.
A webinar, which will be held on June 4, 2020, from 2 to 4 p.m. Eastern Daylight Time, will provide an overview of the cooperative agreements’ purpose, project types, eligibility and basic requirements for submitting an application. Information on how to register and participate in the webinar, or listen to the recording, will be posted at https://www.farmers.gov/manage/urban/opportunities.
