Abstract
A simple and open perfusion system is described for studying the sulphur (S)‐supplying capacity of soils. A range of soils were perfused at frequent intervals and the leachates analysed for inorganic and total S. Results were compared with plant S‐offtake from the same soils. Although greater amounts of S were removed in the perfusion system, data from the two techniques correlated strongly, suggesting the perfusion system can be used to estimate the S‐supplying capacity of soils.
