Establishing a dense stand is critical to realizing a red clover cover crop's full value. During the drought year of 2012, corn grown after red clover likely suffered from a soil water deficit because of water use by red clover, which reduced corn yields compared to the control (Figure 1).

Perennial cover crops such as red clover (Trifolium pratense) are slow growing and are best used in orchards and vineyards. They die over the winter or naturally complete their life cycle by the next spring. Managing Cover Crops Profitably explores how and why cover crops work, and provides all the information needed to build cover crops into any farming operation. In other words, you might look at the field and say, “the wheat looks good but the clover looks poor,” even when the clover is actually doing its job.

It’s relatively inexpensive compared to the mixtures some growers are advocating, some of which can run upwards of $50 per acre. But that leads to another reason why cover crops might have fallen out of favour: the focus on driving wheat yields in the past decade, something Adam Hayes has seen occurring. Preplant nitrogen rates should be based on current MSU recommendations (60 lbs/acre N credit for a 100 percent stand of red clover). Michigan's three common red clover cultivars are Michigan mammoth, Canadian mammoth (also known as Altaswede clover) and June (also known as medium red clover).

Red clover (Trifolium pratense) is Michigan's most common cover crop. Broadcast 10-12 lb/A of seed (Michigan mammoth or June) before the ground thaws. “If you add to that the nitrogen credit, it’s a pretty significant payback, plus all of the soil health benefits you’re getting as well.”. “To build on that concept, our recommendations for N credits used to be worded that if you had red clover that was knee-high, you’d get a full nitrogen credit,” says Deen, adding that it had to be a thick and lush stand to qualify. atrazine).

Michigan mammoth has been shown to perform better than the other red clovers when frost-seeded into well-fertilized wheat (Table 1), but is not as productive a forage crop as June clover. And of course, there’s the ongoing concern about phosphorus levels in the Great Lakes, and that lends itself to growers doing more to reduce erosion and runoff of surface water. His highest overall field yield was after corn following wheat, and a 22-acre field ran 259 bu./ac. To use red clover as a cover crop, the plant is sown in late summer or early fall. Please see contact us for more information. Dense stand red clover. Crown vetch is often used for roadbank stabilization and as permanent groundcover.

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. Subsequent research has shown that frost-seeded June clover performs as well as Michigan mammoth in well-fertilized wheat. The following are just a few. Red clover in 2011-12 contained much N, but that N was likely not used by corn. The clover haylage is under-seeded with his oats in Year 2 and the winter wheat is planted into the clover stubble, which is then fall-killed after the wheat harvest. Broadcast 10-12 lb/A of seed (Michigan mammoth or June) before the ground thaws. But it also takes a shift in grower attitude, he says, with a focus on long-term net economics. 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. Two or three years ago, Hayes monitored long-term plots at the University of Guelph’s Ridgetown Campus, with red clover inter-seeded into the plots at different N rates. This legume provides ample quantities of nitrogen and valuable quantities of biomass that benefit your garden soil. Along with detailed management information on the most commonly used species—including grasses, grains, brassicas and mustards, and legumes—Managing Cover Crops Profitably offers chapters on the role of cover crops in […] Over the past three years, a curious turnaround has spread across Ontario.

Crimson clover dies off in the winter in cold climates. A red clover cover crop has several benefits, including: Red clover is most commonly used in rotations between non-leguminous crops, such as corn or small grains (wheat, oats, barley, rye and spelt) followed by a spring-seeded non-leguminous crop (corn, buckwheat, oats, etc.). atrazine). He acknowledges that he likely doesn’t spend as much on fertility as other growers might but the differences in his practices are obviously a big part of that equation. 2011.

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. Many cover crops are legumes that convert nitrogen from the atmosphere into a soluble form that other plants can absorb. An excellent herbicide program to terminate a red clover stand prior to planting corn is one pint of 2,4-D LVE and one pint of dicamba (Banvel or Clarity). Select fields that have relatively good weed control, as clover seedlings do not compete well with established weeds. His second rotation is a three-year plan, with corn, soybeans and winter wheat. However, if the clover crop is not “killed off” in the fall, then preparing a suitable seedbed to plant next years crop in is often significantly delayed resulting in reduced 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. Canadian-grown mammoth clover does not tolerate the increased shading and competition from well-fertilized wheat, but works well when seeded with oats.
