A good deal of study into the effects of stock excrement on pastures has been carried out by Sears and his co-workers ( 1942, 1948, 1953), and Doak (1952) has investigated chemical changes in sheep urine. Little recent work, however, has been published on certain aspects of naturally voided sheep urine. This paper sets out some preliminary observations of the effects of sheep urine on pasture and its influence on soil test.
