New York Times on No-Till Farming and Cover Crops

The New York Times recently published another article praising no-till and cover crops, citing climate severity, costs, environmental concerns and soil health as prime reasons we’re seeing a “paradigm shift” in agricultural practices. Here’s an excerpt, talking about how cover crops increase organic matter and how that helps to clean up rivers and the Gulf of Mexico:

“Each 1 percent increase in soil organic matter helps soil hold 20,000 gallons more water per acre,” said Claire O’Connor, a staff lawyer and agriculture specialist at the Natural Resources Defense Council.

In turn, more absorbent soil is less vulnerable to runoff and more resistant to droughts and floods. Cover crops also help suppress weeds. Environmental groups like the Defense Council have long been fans of soil-conservation techniques because they help protect waterways and increase the ability of soil to store carbon dioxide, rather than releasing it into the air, where it contributes to climate change.

One recent study led by the Environmental Defense Fund suggested that the widespread use of cover crops and other soil-health practices could reduce nitrogen pollution in the Upper Mississippi and Ohio River basins by 30 percent, helping to shrink the giant “dead zone” of oxygen-depleted water in the Gulf of Mexico. The Defense Council, Ms. O’Connor said, has proposed that the government offer a “good driver” discount on federal crop insurance for growers who incorporate the practices.
