The government writes no subsidy checks to grass farmers. Grass farmers, who buy little in the way of pesticides and fertilizers (none, in the case of Joel Salatin), do little to support agribusiness or the pharmaceutical industry or big oil. A surplus of grass does nothing for a nation’s power or its balance of payments. Grass is not a commodity. What grass farmers grow can’t easily be accumulated, traded, transported, or stored, at least for very long. Its quality is highly variable, different from region to region, season to season, even farm to farm; there is no number 2 hay. Unlike grain, grass can’t be broken down into its constituent molecules and reassembled as value-added processed foods; meat, milk, and fiber is about all you can make out of grass, and the only way to do that is with a living organism, not a machine. Grass farming with skill involves so many variables, and so much local knowledge, that it is difficult to systematize. As faithful to the logic of biology as a carefully grazed pasture is, it meshes poorly with the logic of industry, which has no use for anything it cannot bend to its wheels and bottom line.
