In 43 experiments on a range of soils there was little indication that magnesium sulphate applied to the seedbed increased yield of cereals, potatoes or sugar beet. In one experiment only, on potatoes, a very high rate of muriate of potash induced magnesium deficiency. Different rates of ammonium sulphate, compared on cereals only, did not affect crop response to magnesium. The magnesium content of barley foliage and the effects of magnesium sulphate and ammonium sulphate on this content were shown to be related to soil potassium and magnesium levels.
