Cover crops work. That's the message from the results of a recent study.
Last year's drought gutted corn and soybean yields. But that yield hammer
was much lighter on those crop acres that were preceded by a cover crop.
The study, conducted by the USDA North Central Region Sustainable
Agriculture Research and Education (SARE) program and Conservation
Technology Information Center (CTIC), sought opinions from more than 750
farmers in the Corn Belt on cover crops, how widely they're adopted, their
payback and challenges.    Share this article:   [image: Share on

Cover crops paying off, survey shows

Cover crops work. That's the message from the results of a recent study
released this week.

Last year's drought gutted corn and soybean yields. But that yield hammer
was much lighter on those crop acres that were preceded by a cover crop.
The study, conducted by the USDA North Central Region Sustainable
Agriculture Research and Education (SARE) program and Conservation
Technology Information Center (CTIC), sought opinions from more than 750
farmers in the Corn Belt on cover crops, how widely they're adopted, their
payback, and challenges.

In a year like 2012 especially, their benefits far outweighed any
challenges they posed. In general, the study revealed corn yields in corn
acres following a cover crop netted a 9.6% higher yield than comparable
acres without a cover crop. The same was true with soybeans to the tune of
11.6% higher yields. Those gains sharpened in the driest of the drought-hit
areas last year; corn yielded 11% more in the driest spots, while soybeans
made 14.3% more, the study shows.

"It is especially noteworthy how significant the yield benefits for cover
crops were in an extremely dry year," says University of Missouri
agronomist and regional director of Extension programs for North Central
Region SARE Rob Myers in a SARE report. "The yield improvements provided
from cover crops in 2012 were likely a combination of factors, such as
better rooting of the cash crop along with the residue blanket provided by
the cover crop reducing soil moisture loss. Also, where cover crops have
been used for several years, we know that organic matter typically
increases, which improves rainfall infiltration and soil water holding
capacity."

Those yield improvements likely stem from a number of factors that farmers
identified as soil health benefits from cover crops, according to the SARE
study, including:

   - Reduced soil compaction
   - Improved nutrient uptake and management
   - Declined soil erosion


Planting cover crops does cost more money than doing nothing, obviously.
But the benefits to soil health -- not to mention 10% more corn and
soybeans at the end of the year -- make it worthwhile, many farmers said in
the SARE study. So much so that many say they're ramping up their cover
crop acres this year.

"Farmers are willing to pay an average (median) amount of $25 per acre for
cover crop seed and an additional $15 per acre for establishment costs
(either for their own cost of planting or to hire a contractor to do the
seeding of the cover crop)," according to a SARE report. "Surveyed farmers
are rapidly increasing acreage of cover crops used, with an average of 303
acres of cover crops per farm planted in 2012 and farmers intending to
plant an average of 421 acres of cover crops in 2013. Total acreage of
cover crops among farmers surveyed increased 350% from 2008 to 2012."
