Dolomite was the first fertilizer used to prevent hypomagnesemia (Cunningham, 1936).When applied at rates between 100 and 540 kg Mg/ha the Mg concentration of temperate forage is increased by 0.2–1.2 g/kg DM (Table 9.13).These increases in Mg concentration in the forage were associated with a rise in the level of exchangeable Mg in the soil (Jones, 1963b; Simpson, 1964).
