The effects of fertilizer treatments on the oestrogenic potency of Trifolium subterraneum L

Abstract

The oestrogenic potency of subterranean clover from plots which received superphosphate together with several other fertilizers did not differ significantly from that of clover from a plot which had received superphosphate only. On the other hand, clover from plots which had received no fertilizer recently was significantly more potent than clover from plots which had received superphosphate.
