So, all that is demonstration. Let’s put this to the test to real field conditions and real rainfall. Matt Griggs who is featured as the Number 3 in the Profiles of Soil Health Heroes on tnacd.org and also Matt Griggs update Profiles of Heroes. Matt recently sent me pictures in a rainstorm at his farm, true dedication.
Cover crops add more carbon and increases soil biology that increases better aggregates which results in much greater soil structure, pore space, thus better infiltration rates. Pictures below show long-term no-till with standing water, four years plus of cover crops and no-till with great infiltration, and the bottom picture show where the two plots come together. A picture is worth a thousand words. Cover crops with no disturbances from tillage improve soil function, such as here, infiltration.
Twenty Years of No-till. Two years of multi-species cover crops and no-till.
No-till alone on the left and No-till with cover on the right.
Soil health is improved by not disturbing the soil, keeping a root growing, keeping the soil covered, and diversity. The demonstrations and real farm application show continuous no-till with cover crops improve the soil’s ability to infiltrate water. Better water infiltration means better efficiency of water use and more stable yields.
