That’s according to new University of Illinois research showing cover crop adoption reached 7.2% in 2021, up from just 1.8% a decade prior. The finding is the result of sophisticated satellite-based remote sensing efforts that accurately detected cover crops across 140 million acres of cropland and tracked their expansion over 20 years. “We analyzed the area of cover crops in each year with that year’s funding and we found that it's highly correlated. We also checked the investments across different states, showing some states have higher cover crop percentages that are related to their funding investment,” says Sheng Wang, research assistant professor in NRES and study co-author.
