Can Livestock Help the Adoption of Cover Crops?

The adoption of cover crops is good for farmers and good for the environment. ( Farm Journal )

Despite farmers’ positive perceptions about cover crops and the availability of cost-share programs to incentivize their use, an Iowa State University study shows the return on investment may be the biggest hurdle to overcome for widespread adoption of the practice.

In 2017, Iowa fields planted to cover crops grew to 760,000 acres, with less than half receiving federal or state cost share. But with millions of acres of crops, Iowa — and other Midwestern states — has yet to see widespread adoption of cover crops to reduce nitrates in water from crop fields and to conserve and build healthy soils.

“We have a substantial body of research that shows cover crops have positive long-term benefits for water quality, soil health and the environment,” says Alejandro Plastina, assistant professor of economics and extension economist. “Farmers also have positive perceptions about the value of cover crops and can take advantage of cost-share programs that incentivize their use.”

“But it’s likely that the number of acres planted won’t substantially scale up if the practice doesn’t at least break-even in the short term,” he added.

In the study, Plastina and his colleagues calculated annual net returns to cover crop use by analyzing field data collected through focus groups conducted in Iowa, Illinois, and Minnesota; an online survey with responses from 11 states; and a survey mailed to 1,250 farmers in Iowa. Through the survey and focus groups, conducted in partnership with the Practical Farmers of Iowa organization, the researchers compared each farmer’s costs and revenues from fields where they used cover crops and from fields without cover crops.

Working with Plastina were Fernando Miguez, associate professor of agronomy; Fangge Liu and Wendiam Sawadgo, graduate students in economics; Guillermo Marcillo, graduate student in agronomy; and Sarah Carlson, the strategic initiatives director for Practical Farmers of Iowa.

Using the survey results, the researchers developed partial budgets to evaluate changes in net returns resulting from using cover crops in corn or soybean production.

Overall, the researchers found substantial variability in net returns, driven by the costs of planting and terminating cover crops, feed cost savings from grazing cover crops, cost-share program payments, and the difference in yields obtained in fields with and without cover crops.

“Cost-share payments are a critical incentive to support the practice of cover crops,” Plastina says. “But we found that for most farmers, these payments are insufficient to cover all costs associated with cover crops.”

What Can Tilt the Balance?
“We found that farmers who grazed livestock on cover crops or harvested them for forage or biomass generated sufficient additional revenue or cost savings to result in overall positive returns, in addition to receiving cost-share payments,” Plastina says. “Promoting the use of cover crops for livestock grazing or forage would help a farmer’s bottom line.”

“Anecdotally, farmers may find ways to reduce costs and increase revenues, but from our research we can affirm that is not what Iowa farmers are typically experiencing,” he adds. Also helpful, he added, would be developing improved guidelines to help farmers minimize yield drag on corn and soybeans while containing cover crop planting and termination costs.

“A less sustainable alternative, due to federal and state budget constraints, would be to consider public policies that provide more incentives to adopt cover crops, like more cost-share payments, subsidized seed, discounted crop insurance premiums or tax credits,” Plastina says.

Plastina admits that partial budgets derived on survey data do not account for long-term soil and water quality benefits because no market value exists for soil health or water quality, and neither does a generally accepted method to value them. But this information still provides valuable insight for farmers and policy-makers.

“The calculated returns are based on real field data, not experimental plots, from row-crop farmers who manage acres with and without cover crops,” he says. “This information can be a useful benchmark for current and potential cover crop adopters. It also can serve as a reference for discussions on future agricultural and conservation policy.”

Plastina is developing a website on the economics of cover crops that will include tools for farmers and others to discern potential costs and benefits. The website will include a downloadable spreadsheet with several budget scenarios for cover crops and a simple web-based decision tool to generate estimated net returns to cover crops.

He also continues to conduct research, including an evaluation of the effectiveness of cost-share programs in promoting adoption of cover crops.

The project was funded by the North Central Region of the Sustainable Agriculture Research and Education (NCR-SARE) and the Center for Agricultural and Rural Development at Iowa State.

Farmers are finding ways to reduce costs and increase revenues but it is not getting into reality. Due to climatic changes and other problem they got losses in their production.This article much useful to understand details.Google Chrome running out of memory
