In 2017, he tried subterranean clover in his NE field. Subterranean clover is a cool-season annual legume that produces seeds during the summer at or below the soil surface (hence the name subterranean). Seeds then germinate in the fall after the first rains and grow rapidly through the fall/early winter. It may go dormant for a time during the winter, but becomes active again in early spring. It grows in densely matted clumps that are 6-15 inches tall. The clover spreads through rootless runners reaching up to 3 feet in length. After a few years of trial, Fred reports that the “Subclover cover crop, in what is now our nine-year-old hazelnut orchard, is working very well and is quite easy to manage. Plus, now as the trees have sent roots out in the row centers, we are getting some nitrogen benefits. This orchard was visibly greener than our other orchards last spring. Every year it [the cover crop] gets better without having to add any seed since it is self-seeding.”

The May 7th, 2021 Sustainable, Secure Food Blog explores how wind erosion affects farming in Washington and some solutions farmers can use. According to blogger Andrew McGuire, “Wind erosion is a soil health thief. In both sandy and fine-grained silt soils of Eastern Washington, wind erosion lifts, sifts, and then carries away the best part of the soil. Lost are the tiny particles of clay and silt with the organic matter that is stuck to them.” Local soil conditions make matters worse. Low rainfall produces sparse vegetation, therefore low soil organic matter levels.

“Soil Health is, simply put, the ability to produce marketable outputs with minimal inputs. It’s very important for people to understand that multi-dimensional property is dynamic, it changes over time and it’s dependent on environmental conditions like temperature, moisture and even the microorganisms and worms and all other life that’s present there.”

Extolled as a defense against erosion and nutrient loss during fallow seasons, cover crops are being planted on a larger portion of U.S. cropland than before, said USDA economists.

The new era of climate mitigation on the farm would look like a beefed-up version of longstanding USDA conservation programs, augmented by a carbon bank that sets a floor price for carbon sequestration and reductions in greenhouse gas emissions, said leaders of the Food and Agriculture Climate Alliance (FACA) on Wednesday. “That’s what we’ve modeled it after,” said Chuck Connor, a founding member of the alliance and a former deputy agriculture secretary.

U.S. Farmers & Ranchers in Action (USFRA) —in conjunction with World Business Council for Sustainable Development (WBCSD), The Mixing Bowl, and Croatan Institute has issued a new report that analyzes the state of soil health technology. The report also identifies opportunities to find new sources of capital to scale up the adoption of climate-smart agriculture on U.S. farms and ranches.
