Soil organic matter is decomposed organic material (leaves, roots, microorganisms) that exists in the soil and acts as a reservoir of water and nutrients. “The phacelia did very well; it just kept on blooming and blooming,” says Gartner. Soil Building Mix: Legumes + Brassicas + Some Grasses. Many analogies have been drawn likening organic matter in the soil to a sponge, a medium in which water and nutrients are stored. Non-legume cover crops, including grasses and brassicas, were found to increase soil organic matter levels by 4% to 62%. If conditions prevent grazing of the cover crop, he simply no-till drills the next year’s cash crop into the standing residue. The intent was to harvest the oats for hay. Gabe Brown and Jay Fuhrer, a soil health specialist with NRCS in North Dakota, viewed a cocktail cover crop mix on the Brown Ranch in 2012. $2.20 / lb. Using Cover Crops to Improve Clay Soil.
