Joel Salatin of Polyface Farm (polyfacefarms.com) in Virginia’s Shenandoah Valley recommends rotational grazing to caress soils and confuse pathogens. The Salatins delight in diversity and prefer portable, flexible animal infrastructure. They blend and rotate livestock and pasture species to puzzle pests. Soils rest between rotation cycles to nurture nutrients and to break pest and pathogen patterns.
For centuries farmers have understood that animal manures return vital nutrients to crop fields. Many farmers pull mechanical spreaders behind fossil fuel-burning tractors to move manure into fields. At Polyface farm, livestock spread their own manure.
Rotational or mob grazing simulates large herds of bison grazing and moving across the American prairies. Well managed grazing concentrates livestock in one area for a short period and then move them on. At Polyface farm, portable electric fences contain grazing beef herds. Farmers move the fences and livestock daily. Salatin said his animals look forward to a fresh “salad bar” every morning. These cattle graze forage at a sustainable level. They trample their manure patties ensuring good soil contact and starting the decomposition process. [Read more here.]
