Grass tetany is a nutritional disease of ruminants caused by low dietary Mg. Previous research shows that early spring P-fertilization increases the leaf Mg in tall fescue hay. But how does P-fertilization affect the mineral concentration? We compare, under grazing, the Mg, K, Ca, and P concentration of tall fescue when soil P was considered either adequate or low.
