Synopsis There were differences in yield, SO 4 ‐S concentration, and total S uptake among competing species growing at different levels of available S. Yield response to S increased as the season advanced, but the concentration of total S and SO 4 ‐S in the plants decreased. The SO 4 ‐S concentration in each of the species where no S was applied was indicative of S deficiency. The SO 4 ‐S concentration in subclover at flowering appeared to be the best single indicator of S status.
