2016-2017 Cover Crop Survey

The 2016-2017 Cover Crop Survey Report from the Sustainable Agriculture Research and Extension (SARE) program, Conservation Technology Information Center (CTIC), and American Seed Trade Association (ASTA) has been released.

 

What does the data have to say about the use of cover crops?

 

According to a nationwide survey, following the use of cover crops farmers reported increased yields of corn, soybeans, and wheat and improvement in the control of herbicide-resistant weeds. In addition, the survey of 2,012 farmers showed acreage planted in cover crops has nearly doubled over the past five years.

Survey participants- 88% of whom use cover crops- reported that after cover crops:

  • Corn yields increased an average of 2.3 bushels per acre, or 1.3%
  • Soybean yields increased 2.1 bushels per acre, or 3.8%
  • Wheat yields increased 1.9 bushels per acre, or 2.8%

This marks the fifth consecutive year in which the survey reported yield increases in corn and soybeans following cover crops. It is the first year the survey team was able to calculate the impact of cover crops on wheat yields.

 

Herbicide-Resistant Weed Control

“In addition to yield increases, farmers reported other benefits to cover crops, ranging from improved soil health to better control of herbicide-resistant weeds,” notes Rob Myers, Regional Director of Extension Programs for North Central SARE at the University of Missouri. “For instance, 85% of the farmers who used cover crops said they have seen improvements in soil health. That reflects long-term thinking and a growing understanding of the enduring value that cover crops deliver.”

Myers adds that 69% of the respondents said cover crops always or sometimes improved control of herbicide-resistant weeds. That is a significant number, he notes, as a majority of respondents- 59%- reported having herbicide-resistant weeds in at least some of their fields.

 

Planting Trends

Since SARE and CTIC began their annual cover crop survey in 2012, there has been a steady increase in cover crop acreage among participants. In this year’s survey, farmers said they committed an average of 400 acres each to cover crops in 2016, up from 217 acres per farm in 2012. They expected to increase their cover crop planting in 2017 to an average of 451 acres.

The timing of cover crop planting is also evolving. Cover crops are typically planted in the off-season from cash crops, providing ground cover, nutrient sequestration and scavenging, weed suppression, and soil health improvements. Approximately three out of four cover crop acres in the survey were planted after harvesting a cash crop, but the practice of inter-seeding covers into growing cash crops is an emerging trend- 27% of the respondents said they seeded cover crops at side-dress fertilization time or in late summer.

At the other end of the cycle, “planting green”- seeding cash crops directly into living, green cover crops, then terminating the covers- had been tried or used by 39% of the respondents. They said the approach helped suppress weeds, manage soil moisture, and maximize other benefits of cover crops. Planting green was uncommon just a few years ago.

Business Opportunities

The last USDA Census of Agriculture found that farmers planted more than 10 million acres of cover crops in 2012. The new agricultural census, which will begin this fall, is likely to find several million additional acres of cover crops planted in 2017.

The growth of cover crop use is likely to expand a range of business opportunities throughout agriculture. Twelve percent of the surveyed cover crop users hired aerial applicators to seed their cover crops, while 8% hired an ag retailer or co-op, and 6% hired another farmer to do the planting. When asked who they wanted to buy cover crop seed from in the future, 43% said they would like to buy from specialized dealers.

“The SARE/CTIC Cover Crop Survey is a great opportunity to gather insight into the purchasing decisions of farmers when it comes to cover crops,” ASTA President and CEO Andy LaVigne says. “The data from the previous four years’ surveys shows this is an important time to be involved in this space within the agriculture community, and ASTA members are pleased to support the efforts of SARE and CTIC to gain insight into the cover crop seed needs and requests of farmers nationwide.”

Cover Crop Motivations

“One of the most important outcomes of the SARE/CTIC Cover Crop Survey is insight into what motivates farmers to use—or start using—cover crops,” notes Chad Watts, Executive Director of CTIC in West Lafayette, Indiana.

“Among cover crop users, we are seeing great enthusiasm for the soil health benefits of cover crops, with a widespread appreciation for the long-term benefits of covers,” Watts notes. “We’re also seeing openness to practices like inter-seeding and planting green, which raises cover crop use to the next level in terms of creating new options for species and mixes, and new opportunities to get even greater benefits from their covers.

“Among non-users, we’re getting a strong signal that they want more information and training,” he adds. “The feedback we’re hearing through the survey will help guide the research and extension agenda to gather and share the information farmers need in order to adopt and succeed with cover crops.”

In addition to the contributions of SARE, ASTA, and Purdue, support for the survey was provided by ASTA members Beck’s Hybrids, Grassland Oregon, Justin Seed Company, La Crosse Seed, Monsanto, and Seedway, with additional help from Penton Agriculture.
