Insight from 2,020 farmers from across the country found that the planted acreage of cover crops continued its steady rise - reaching an average of 298 acres per farm in 2015 and projected to grow to a mean of 339 acres in 2016. Those figures are more than double the acreage survey participants said they planted in 2011.
After cover crops, corn yields rose an average 3.4 bushels per acre, or 1.9 percent, after cover crops, and soybean yields increased 1.5 bushels per acre, or 2.8 percent. Analysis of the survey data revealed that yield increases rose to 8.3 bushels per acre of corn after cover crops had been used for more than four years on a field. In soybeans, the average yield gain increased from 0.1 bushel per acre after a single year in cover crops to 2.4 bushels after four years of cover crops. Learn more in the full report here
A survey of more than 1,200 farmers across the country revealed that cover crops boosted corn yields last year by a mean of 3.66 bushels per acre (2.1%) and increased soybeans by an average of 2.19 bushels per acre (4.2%)—the third year in a row a yield increase following cover crops was recorded by the Conservation Technology Information Center (CTIC) Cover Crop Survey.

Sustainable Agriculture Resaerch and Education (SARE) program and CTIC conducted a national survey of farmers to learn more about their use of cover crops. More than 1,900 farmers completed the survey, which was a follow-up to a smaller survey in 2012-2013 (see below). Results show a yield boost from the use of cover crops in corn and soybeans, data on the costs of seed and establishment, the challenges and benefits farmers expect from cover crops and insight into how farmers learn to manage cover crops.

2012-2013 Cover Crop Survey
Sustainable Agriculture Research and Education (SARE) program and CTIC conducted the first cover crop user survey. More than 750 farmers from across the U.S. completed the survey, representing hundreds of thousands of acres of cover crops and drawing on cover cropping experience that goes back as far as 1948. The 2012 crop year was a challenging one in which to study yield impacts – much of the U.S. was impacted by drought, which pushed national per-acre corn production estimates down by 43.7 bushels, or 26.3%, and reduced soybean production by 8.1%, or 4.0 bushels per acre, based on early-season predictions from the U.S. Department of Agriculture Economic Research Service. However, even in those conditions – or perhaps because of them – the survey revealed a positive impact of cover crops on yield. The results of the 2012-2013 survey can be found here

Helping People, Land and Water: The Cover Crop Story
What do farms, water quality and the Great Lakes have in common? They all are helped by cover crops. Through the Great Lakes Cover Crop Initiative
, CTIC and partners planted 36,970 acres of cover crops, providing many benefits to farmers in the Great Lakes region. Hear from three farmers in the Great Lakes basin, a researcher on Lake Erie and a Michigan State University Extension educator as they present "The Cover Crop Story."
Cover Crops - An Essential Tool for Sustainable Cropping Systems
The use of cover crops is steadily increasing throughout the United States. Many no-till farmers consider cover crops to be the next step in conservation agriculture.
Leaving the soil undisturbed and keeping something growing as many days as possible restores the natural cycles of the soils. Residues and roots create more organic matter in the soils. Increased organic matter serves as a food source to various soil organisms and increases the biological activity. Higher biological activity increases nutrient cycling and availability and also reduces nutrient loss due to run off. With all this activity, soil structure and tilth are improved, increasing infiltration rates and reducing compaction.
