Overseeding into standing corn immediately after sidedressing nitrogen or the last cultivation (whichever is later), or before a spring annual's emergence (oats, spring wheat) also provides a good stand. The work conducted at the university’s Elora Research Station is detailed and it spans several decades, and most if not all of it points to cover-crop benefits including better soil health and improved yields. Although he relies on red clover as a cover crop in some parts of his two rotations, Barrie emphasizes that it’s a valued source of forage for his dairy herd. He can switch between the five- and three-year rotations, depending on distance from the home farm and his need for haylage. He follows two rotations, one that’s five years with soybeans, oats, clover haylage, winter wheat and corn. Crimson clover is a cool-season legume that reduces erosion. The lateral roots growing off the main tap root will concentrate in the top 5 inches of topsoil. The cost of seeding red clover is more than covered by the additional nitrogen provided to the following corn crop.

As a cover crop, red clover is used primarily as a legume green manure killed ahead of corn or vegetable crops planted in early summer. Note the cotyledon leaf is still visible. Red Clover. In spite of those findings, red clover continues to be an easy way to get back into growing cover crops. Full-season, over-wintered red clover can produce 2 to 4 T dry matter/A and fix 70 to 150 lb. But that can be deceptive with clover. Again, use a post-emergence broadleaf program instead of establishing a clover stand in corn treated with a pre-emergence broadleaf herbicide (i.e. MSU is an affirmative-action, equal-opportunity employer. “I’ve talked to dealers or retailers of red clover and they’ve said that as soon as a farmer gets a no-till drill, his complaints on red clover stands go up.

Although he has also noticed an increased focus on multi-species cover crops (if growers can make such a system work on their farms, he says, that’s great), he also sees a role for the single-species approach.

Others attribute it to the increased attention on soil health and sustainability. Planting earlier is the easiest way to overcome complaints about not getting that “good catch of clover.”. Cover crops are always seeded directly in the ground, rather than transplanted from pots. Clover seedlings are resistant to frost, so the seed can be broadcast as early as soil conditions permit. Red clover’s high adaptability and biomass yield makes it one of the most ideal candidates for cover crops across the United States and world. “There’s been some work done to try to help improve the stands, seeding it earlier,” says Hayes, field crop soil specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA). In that scenario, clover is a winner, he says.

Select fields that have relatively good weed control, as clover seedlings do not compete well with established weeds. Deen and his colleagues have studied the impact of tillage on red clover, and some of that research indicates that red clover doesn’t perform well under a no-till management system.
