Field Crops

Field-crop farmers are still the largest membership contingency at Practical Farmers. Learn about our work with these farmers to improve their profitability, stewardship and farmer-to-farmer community.

Field-crop farmers are still the largest membership contingency at Practical Farmers. The Field Crops Program at Practical Farmers of Iowa works with farmers raising corn, soybeans, small grains, alfalfa, red clover and other perennials. Their systems range from conventional to organic production, no-till, ridge-till, strip-till or low-input. Many of these farmers integrate livestock and cover crops into their production systems. Cover crops, small grains and soil health have been identified as priorities in recent years.

Small Grains

Small grains crops like oats, wheat, barley, rye and triticale are seeing renewed interest by farmers in Iowa. Practical farmers members and others are generating information about how to source see, plant, manage and harvest these crops.

U.S. Testing Network

Practical Farmers works with corn breeders and seed companies to combat the lack of choice of corn genetics in the marketplace.  The US Testing Network (USTN) is a group of independent seed companies, public corn breeders and private corn breeders who work with PFI’s Breeding Corn for Sustainable Ag network to test non-GMO corn hybrids across the eastern US. Their goal is to improve the quality and quantity of non-GMO corn hybrids available in the marketplace.
