Nutrient Cycling in Grazed Pastures^{1, 2,}

Pastoral Research Laboratory, Armidale, N.S.W., Australia

Abstract

The experiments reported demonstrate the feasibility of, and describe techniques in, using radiotracers in field studies of the sulphur cycle in a grazed pasture system and it is suggested that other nutrients may be studied using similiar techniques. The radiotracer method allows direct estimates to be made of recycling and leaching as well as the sizes of various sulphur pools in virtually undisturbed systems. A diagram of a sulphur cycle is presented which, together with pool sizes and specific radioactivity transients, is used to indicate areas for further research and to stress the importance of studying the whole system.
