SUMMARY Pot ale is a waste product of malt whisky distilling. Experiments were performed to establish the effects of its disposal on hill land and whether it could be used as a liquid fertiliser on rotational grass and on barley. Heather cover was drastically reduced by frequent low doses of pot ale, but infrequent heavy doses left heather moorland relatively unchanged. Total annual applications of pot ale of over 100 m 3 /ha to lowland grass swards increased yields of dry matter. Yield of barley was also increased by applications exceeding 100 m 3 /ha application. Other aspects of disposal of pot ale are considered.
