Organic farming is more profitable than conventional farming, according to a new report that analyzes dozens of studies, including some from Minnesota and Iowa.
The analysis, published in the Proceedings of the National Academy of Sciences, found that the premium organic farmers can charge for their products makes their operations financially sustainable.
"We found that, in spite of lower yields, organic agriculture was significantly more profitable than conventional agriculture and has room to expand globally," said study co-author David Crowder, assistant professor of entomology at Washington State University.
Crowder and John Reganold, a soil science professor at the same university, analyzed 44 studies comparing the financial performance of organic and conventional agriculture, which included 55 crops grown in 14 countries. They found that if organic farmers did not charge a premium, they made less than conventional farmers, but when they did charge a premium, organic agriculture was 22 to 35 percent more profitable.
The results were not a surprise to Robert King, University of Minnesota professor in the department of applied economics.
"We've looked at the literature on this time and time again," King said. "The result is that on a per-acre basis, especially with organic premiums, organic comes out to be more profitable."
Organic farming does not use synthetic chemicals and genetically modified organisms, so King said organic growers don't spend as much on herbicides and premium seeds as conventional farmers. But because organic growers don't use weed killers and need to cultivate, he said, they spend more on labor and usually receive lower yields per acre, depending on the crop.
"The costs for each system are pretty much a wash," King said, but organic farmers make more money because their products fetch higher prices. For the past five years the university has been following the progress of Minnesota farmers that are transitioning to organic, he said.
