Gabe Brown's system uses a wide array of cover crops mixed together. He claims the variety of root systems left in the soil is one of the major components to building healthy, high brix soil. I am researching cover crops now, as well. Don't overlook compost tea and raw milk as well. Some guys here are having good luck with rye as a cover crop. My elevation here is only 4,000 feet, but very alkaline conditions with wide temperature swings.
