Abstract

Possible reasons were examined, by use of soil and plant analysis, for a response to lime by white clover (Trifolium repens) on the coastal lowlands of south-east Queensland. The response, followed over a five year period, was to a single application of 2,000 kg lime ha-1. The response could possibly be due to increased pH (from pH 5.0 to pH 5.4) but is more likely to be due to increased calcium status in the clover (from 1.0 to 1.3% in leaf samples). It is not considered that the response was due to increased availability of manganese or aluminium.
