SARE/ASTA/CTIC Cover Crop Surveys
2016-2017 Cover Crop Survey
Click here to view the full report of the fifth annual cover crop survey. A big thank you to the USDA's Sustainable Agriculture Research and Education program (SARE) and the American Seed Trade Association (ASTA), with help from Penton Media through their Corn and Soybean Digest publication. For results from previous years, please see below.
The fifth annual cover crop survey by the Sustainable Agriculture Research and Education (SARE) program and the Conservation Technology Information Center (CTIC) draws on the insight of 2,102 farmers—88 percent of whom reported using cover crops and 12 percent who identified themselves as non-users—from across the U.S. Cereal rye remained the top choice of farmers for cover cropping, followed by oats and radish. Sixty-five percent of the cover crop users reported planting mixes in 2016.
2015-2016 Cover Crop Survey
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.
2014-2015 Cover Crop Survey
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.

2013-2014 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. Read the full report. See the news release for highlights.
Results from the 2013 SARE/CTIC Cover Crop Survey were cited by USDA NRCS Chief Jason Weller in testimony on Capitol Hill. Our survey was also referenced in a New York Times Article - "Cover Crops, a Farming Revolution with Deep Roots in the Past."
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
Cover Crops - An Essential Tool for Sustainable Cropping Sys
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.
Implementation of cover crops can have the following beneficial effects:
- Increase soil organic matter
- Increase infiltration of water into the soil
- Decrease runoff to nearby waterways
- Decrease soil erosion and transport to nearby waterways
- Conserve soil moisture
- Reduce soil compaction
- Increase nutrient availability to the crop
- Reduce nitrate leaching to groundwater
- Supply nitrogen to following crop
- Suppress weeds, potential reducing the need for herbicides
- Suppress soil-born diseases and nematodes, potentially reducing the need for insecticides
- Attract beneficial insects such as pollinators
- Increase yields of the following crop
- Improve soil quality
