Animals of the Serengeti, during the wet season, have acre upon acre of grass to graze which grows quickly due to the rains, the lack of poisonous anthelmintic/deworming agents which lead to soil sterilization, and the presence of large quantities of animal dung which is recycled back into the soil by the action of dung beetles, fungi, and soil-borne microorganisms.
Through a generous award of Carl D. Perkins Career and Technical Education funds, compost tea-making equipment will be installed at the College Farm in Spring 2012 which will allow injection of compost tea into drip irrigation system in the Eagle Eye Demonstration Garden and into new irrigation system for 5 acre pasture using K-Line irrigation equipment.
For those unfamiliar with the background and use of compost tea: Small volumes of compost tea as an urban gardener might use can be mixed in simple equipment. For larger volumes, compost is added to a mixing tank from which it is sucked up into a large tank which has been fitted with a vortex generator. This generator forcibly oxygenates the water via its action in vigorously forcing air into the water along with the compost. Among other vendors, Sabino Cortez of Erath Earth in Dublin, TX sells equipment for the express purpose of producing compost tea on a large scale, to couple with intensive grazing over the summer months of pastures consisting of common and Coastal Bermuda grass. He authored an excellent article for Acres USA entitled Serengeti-Style Grazing.
With the addition of cattle with the right genetic foundation, compost tea and intensive Serengeti-style grazing can form an excellent basis for organic, grass-fed beef production.
