Small grains are a unique crop in the Midwestern system because they are harvested early – around July – leaving the field open for different field operations and cover crops. This longer window makes it possible to grow a legume cover crop that can synthesize nitrogen and offset purchased fertilizer costs for the following crop […]

“We started planting cereal rye because it was easy to calve in. Now, most all of our covers are grazed as a way to justify the costs,” said Mark Schleisman, of Lake City. Cover crops that are grazed have value, but how much value? A three-year PFI research project, initiated in 2015, helped quantify this value […]

Are you growing rye or winter wheat for grain or seed this year? What’s the plan after your harvest? If you’re looking to add nitrogen for a 2019 corn crop, now might be the time to think about frost seeding red clover into that rye or wheat in late February. Red clover as a green […]

Cover crops are typically either aerially seeded into standing crops around the time of physiological maturity in late summer or drilled immediately following crop harvest in the fall. However, on occasion time does not permit one to get a cover crop seeded in the fall or the cover crop fails to establish. In 2017, farmer-researchers […]

In Iowa, cover crops are typically either aerially seeded into standing corn around the time of physiological maturity in late summer or drilled immediately following corn harvest in the fall. However, the earlier one can seed a cover crop, the more potential for growth and biomass production. An earlier seeding date also opens up the […]

Dave and Meg Schmidt operate a diverse livestock farm, Troublesome Creek Cattle Co., in Exira IA; raising grass-fed and finished cattle and sheep, pigs and poultry. Feeding the 100% grass-fed cattle herd over the winter is a great expense, so they have experimented with feeding different forage sources- hay, cover crops, crop residue and stockpiled […]

A roller-crimper presents farmers the opportunity to mechanically terminate cover crops without chemicals or tillage. This method is dependent on a large amount of cover crop growth and the cover crop reaching the flowering stage before crimping. A roller-crimper is a large, metal cylinder with “chevron” pattern blades that simultaneously lays the cover crop flat […]

How does a cover crop affect corn and soybean yields? Winter Cereal Rye Cover Crop Effect on Cash Crop Yield: Year 9 is now available! This is a long-term project being conducted by Iowa Learning Farms and Practical Farmers of Iowa. Between 2009 and 2017, 12 farmer-cooperators have contributed to 63 site-years of on-farm research to investigate what effect […]

Successfully raising corn after a cover crop requires timely cover crop termination and N fertilization. Commonly, farmers terminate a cover crop 2-3 weeks prior to planting corn but generally do not need to apply any more N than if they did not use a cover crop. Last year, PFI farmer-cooperator Dick Sloan attempted “planting green”: planting […]

Increasing rates of cover crop use on rented ground is the next frontier in improving water quality, promoting soil health and improving farmers’ resilience and not all of this rented land is privately owned. Local, state, and federal agencies own a large amount of land in the U.S. for the purpose of protecting natural resources and providing public infrastructure […]
