Case Studies Show Economic Benefits of Soil Health Practices

Soil health practices such as cover crops and no-till can result in an economic return of over $100 per acre, according to a set of case studies jointly released by the National Association of Conservation Districts and Datu Research.

Cover crops and no-till can limit soil loss, reduce runoff, enhance biodiversity and more. Naturally, growers who are considering adopting these practices are keen to know how they will affect their respective farms’ bottom lines.

“These case studies quantify for producers, policymakers and researchers alike what the economic advantages of using no-till and cover crops are, and why it makes good sense for farmers to try them and for organizations like NACD to support and even incentivize their use,” says Jeremy Peters, CEO of the National Association of Conservation Districts (NACD). “We have loads of anecdotal data that says conservation practices benefit the land and producers’ pocketbooks, but now we have run the numbers and know how much.”

During the three-year study period, corn and soybean growers experimented with cover crops and/or no-till, and quantified the year-by-year changes in income they attributed to these practices compared to a pre-adoption baseline. They found that while planting costs increased by up to $38 per acre:

  • Fertilizer costs decreased by up to $50 per acre;
  • Erosion repair costs decreased by up to $16 per acre; and
  • Yields increased by up to $76 per acre

The studies also found that with adoption of these conservation practices, net farm income increased by up to $110 per acre. Included in the growers’ calculations was the considerable time they spent attending workshops or searching the internet to learn about no-till or cover crop practices.

“That time turns out to be an excellent investment, when bottom lines start improving,” says Marcy Lowe, CEO of Datu Research, which conducted the case studies in partnership with the NACD. “Farmers who switch to these practices can see losses at first. But thanks to these case studies, farmers who are generously sharing what they’ve learned, that learning curve will speed up for other farmers.”

One of the case study subjects, Michael Willis, farms 1,000 acres in northwestern Missouri with his family. His advice for future cover crop adopters is this: “Start small enough so it doesn’t freak you out, but large enough to matter.”

Datu Research and NACD intend to continue contributing to the scientific literature on the economic advantages of implementing conservation practices and systems on working lands. The case studies released today can be viewed and downloaded here. The parent report is available on request.
