The vehicle may be acetone or a C 1-3 alcohol, e.g. ethanol. The carrier may be magnesium, calcium or aluminium silicate bearing mineral, e.g. hydrobiotite, or attapulgite clay, diatomaceous earth, a carbonate, chloride, phosphate or sulphate of Na, K, Mg or Ca, e.g. NaCl, CaCO 3 or dicalcium phosphate ground corn cobs, sugar cane bagasse, dried molasses, beet pulp, corn grits, steamed solvent-extracted bone meal, dried pea bulls, dried potato pulp or polished rice.
