“A new study, published in January in the journal PeerJ, looks at how regenerative farming practices — soil-building techniques that minimize plowing, use cover crops, and plant diverse crops — affect the nutritional content of the food.
Results of the preliminary experiment, which included 10 farms across the U.S., show that the crops from farms following soil-friendly practices for at least five years had a healthier nutritional profile than the same crops grown on neighboring, conventional farms. Results showed a boost in certain minerals, vitamins and phytochemicals that benefit human health.
“We couldn’t find studies that related directly to how the health of the soil affects what gets into crops,” said lead author David Montgomery, a UW professor of Earth and space sciences. “So we did the experiment that we wished was out there.”
