Getting the greatest benefit out of cover crops requires a management level on par with corn and soybeans. Growers should start by testing a cover crop on a single field and expand.
Jeff Olson of Winfield, Iowa, certainly sees the benefits of employing cover crops — not only in terms of his yields, but also how they have reinvigorated the soil.
In this video from Michigan State University, Paul Gross shares cover crop recommendations for fields with compacted soil, why you want to choose covers with a tap root, why red clover, alfalfa or radish might be good choices and more.
In this week's edition of the Cover Crop Strategies podcast, brought to you by La Crosse Seed, we’re paying a visit to west central Illinois, where we find fifth-generation farmer Andrew Reuschel hard at work, wrapping up another long day of planting.
Legumes still can provide valuable N to today’s cropping systems. Legumes also contribute a non-nitrogen rotation effect due to addition of soil organic matter and improvement in soil health. Corn grown following alfalfa stands that are 2+ years old (and contained at least 50% alfalfa) require no nitrogen fertilizer on many soils. Red clover N credits are less than for alfalfa.
Red clover can be an excellent green manure that fixes nitrogen, suppresses weeds, and increases corn yields. As a slow-growing cool-season legume, it is suitable to undersowing into winter small grains in early spring. Read more in this article from the University of Nebraska.
