Description
The effects of phosphorus (P) and potassium (K) application on subterraneum clover (Trifolium subterraneum) cv. Mount Barker dry matter (DM) yield were measured in cutting and grazing experiments. Residual nitrogen (N) in soil, after 5 years, was estimated by growing wheat with different N rates. The soil is of volcanic ash origin and has high P retention. The annual rainfall is around 1300 mm, mainly in winter. P application increased DM production (3-7 I/ha/year on average), the clover proportion and the available P in soil (0-50 mm depth). The available N in soil increased from year to year, being 130 mg/kg at the end of the experiment. Wheat after clover yielded more than 4.0 I/ha without N application.
