A study finds regenerative farming is not only good for soil and crops, but also makes food more nutritious—and there’s a role for biotechnology.
The key finding: “regenerative soil-building farming practices can enhance the nutritional profile of conventionally grown plant and animal foods,” says a recent study led by the University of Washington's David Montgomery.
What’s regenerative farming? It’s things like using cover crops, crop rotation, and low-till or no-till farming—techniques developed by one of our favorite scientists George Washington Carver. These techniques can regenerate “healthier soil with more carbon,” explains Mongabay, reporting on the study.
Digging deeper: “Food grown on the regenerative farms, they found, contained, on average, more magnesium, calcium, potassium and zinc; more vitamins (including B1, B12, C, E and K), and more phytochemicals. They were also lower in elements that can be detrimental to human health, including sodium, cadmium, and nickel,” says Mongabay.
There’s a direct link between soil health and human health: “Most notably, soil health appears to influence phytochemical levels in crops, indicating that regenerative farming systems can enhance dietary levels of compounds known to reduce risk of various chronic diseases,” conclude the study authors.
Biotech can enhance this process. “Researchers at the Salk Institute of Biological Studies are using genetic engineering to develop plants with bigger, deeper roots which will stay in the ground after the crop is harvested,” explained BIO’s Connor McKoy. “Over time, these roots will break down slowly, helping to replenish the soil with carbon.”
The challenge now? We’re facing a soil shortage, because soil is a finite resource and we’re losing a lot of it due to erosion, the UN has warned—all the more reason to advance technologies to boost soil health and productivity.
Biotech helps with that too. Herbicide-tolerant crops developed through biotechnology facilitate expansion of conservation tillage, especially no-till. Conservation tillage reduces loss of topsoil while enhancing wildlife habitat. Studies (like this one) have shown tandem increases in farmers’ adoption of biotech traits and conservation tillage.
Do you know the next George Washington Carver—or Rosalind Franklin?Nominations are now open for BIO’s prestigious awards honoring biotech game-changers: the George Washington Carver Award, recognizing an individual who has advanced biotech innovation to make supply chains greener, and the Rosalind Franklin Award, recognizing a pioneering woman in agricultural and environmental biotechnology. Nominations are open through June 24 and the winners will be announced at BIO IMPACT in Omaha in September.
