Netting out what comes below, as explained in paragraphs 11-18: always plow valleys downwards and ridges upwards. This is the heart of Keyline subsoiling and the major unrecognized aspect of contouring which can actually cause erosion to increase. Next is the plow itself. Virtually all plows and discs are designed to kill plants and …
Steve Nelle is one of the leading NRCS scientists practicing today. We tried to get the authors of Habitat Guidelines to visit Circle Ranch and meet with Savory, who journeyed from Zimbabwe for this purpose.I even offered to pay airfare. None attended.
I had already read the Briske paper and realized that it tested Short Duration Grazing systems and not planned grazing. But when the Authors of Habitat Guidelines for Mule Deeroffered it as proof of their conclusions against planned grazing, I wrote Dr. Briske this letter and copied the Authors.
Rather than send a long, separate response, I decided to try an interlined response, dealing with these points one at a time. I hoped that doing it this way would get the authors to focus point-by-point.
I wrote this for Holistic Management International’s semi-monthly publication In Practice, discussing the Mule Deer Working Group’s unwillingness to amend its conclusions which misstated the scientific basis for their advice against planned grazing.
In this paper, highly-respected Texas A&M range scientists Dr. David Briske et al. conclude that planned grazing has been disproved, and that low-density set-stocking is the best grazing protocol. The paper reaches seven basic conclusions:
When the original settlers came, they took their teams and wagons up the valley bottoms. The wagon wheels nicked the turf, and this started gullies which can develop violently during fast runnoff. Left untreated, these will eat whole valleys.
