Cover Crops
Practical Farmers provides farmers and agency personnel with information, anecdotes and research about adding cover crops 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 1,282,608 acres of cover crops in 2022 in Iowa. Practical Farmers of Iowa has played a central role in bringing about this transformative change to the landscape.

Why cover crops?
Watch the “Cover Crops to Improve Soil Structure and Water Infiltration” video below to hear farmers share stories of how covers have improved soil quality and protected their fields during times of heavy rainfall and times of drought. To learn more about cover crops, watch PFI’s “Cover Crops and Weed Control” video.
Want to watch more videos on cover crops? “Practical Cover Croppers” aims to offer a digestible snapshot of PFI members’ cover cropping practices and insights across a range of farm enterprises, from row crops and livestock to horticulture.

Cover crop shared learning calls are conference calls where you can listen and talk with other farmers with varying cover crop experience. Each month our speaker(s) share their experiences and production practices for 40 minutes, and then we open the floor for questions and discussion. Cover crop shared learning calls will take place on the third Friday of the month from noon-1 p.m. during August and September.
We use Zoom to host these virtual events. To participate in shared learning calls, you can either join by phone or computer.

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.
