Abstract
Sulphur responses by caucasian clover (Trifolium ambiguum) were investigated on a sulphur (S) deficient high country site where 4-year-old plants were showing S deficiency. Clover responses from a December harvest were maximum at 40 kg S/ha, but foliar S values remained low at 0.12% and did not increase at the 80 kg S/ha rate. Foliar and soil P values were also low. Foliar analyses of caucasian and white clover samples from another high country site and two fertile lowland sites showed that the two species differ only in their Na and K contents with white clover having higher values than caucasian clover.
