Practical Farmers provides farmers and agency personnel with information, anecdotes and research about adding cover crop to current conventional, organic or other farming systems.
Cover crops are plants such as small grains, legumes, brassicas and others that are planted between cash crop seasons to keep a living cover on the landscape. Numerous studies have shown these plants can help protect soil and water quality, reduce chemical input costs, improve farm resiliency, boost yields, increase forage availability and improve wildlife habitat. In Iowa, the number of cover crop acres has increased dramatically over the past several years — from fewer than 10,000 acres in 2009 to about 600,000 acres in 2016. Practical Farmers of Iowa has played a central role in bringing about this transformative change to the landscape.

Economic Value of Cover Crops (ILF)
A recent study, conducted by Iowa Learning Farms (ILF), Iowa State University Extension and Outreach, and Practical Farmers of Iowa, was to find the economic value of reduced soil erosion and reduced nutrient loss from cover crop use.
Cover Crop Termination Guidelines (NRCS)
To ensure that USDA policies are coordinated and up to date with evolving cover crop practices, the administrators of the Natural Resources Conservation
Service (NRCS), Risk Management Agency (RMA) and Farm Service Agency (FSA) organized an interagency workgroup to develop consistent, simple and
flexible policy across the three agencies.

Tools
Midwest Grazing Exchange
Expanding integrated crop-livestock systems can offer a range of benefits for farmers, the environment and rural communities. But accessing land to graze, or finding livestock farmers to partner with, can be a barrier.
The Midwest Grazing Exchange is a free matchmaking service that aims to connect graziers seeking land to graze with landowners in six Midwestern states. It was created to help farmers in Illinois, Indiana, Iowa, Minnesota, Missouri and Wisconsin find livestock or land to graze.

Partners
With cover crops promising such tangible benefits for farmers and the environment, Practical Farmers is working to increase cover crop use in Iowa and the Midwest. Iowa Learning Farms has been a key partner in these efforts, as well as the Natural Resources Conversation Service, USDA Agricultural Research Service, Leopold Center for Sustainable Agriculture, the Iowa Department of Agriculture and Land Stewardship and the Risk Management Agency. In addition several private companies including seed-houses, aerial applicators and cooperatives have also worked with Practical Farmers to decrease barriers for farmers wanting to add cover crops.
