When light dressings of 0·75, 1·50 and 2·25 cwt muriate of potash per acre (60% K2O) were applied in autumn and spring to swards receiving two levels of sulphate of ammonia, 30 or 60 lb N/acre, and kieserite (29% MgO) at 0, 4 or 12 cwt/acre, magnesium content was reduced as the level of muriate of potash increased. Autumn application resulted in a higher magnesium content, at the expense of the amount of the potash absorbed in the spring herbage. The effects at the lowest levels of application of muriate of potash were slight and became insignificant in later herbage samples.
