Description
A comparison was made of pasture production from phosphate fertilisers, including superphosphate, reactive phosphate rocks (RPRs) and a non-reactive phosphate rock at two sites on the Southern tablelands of NSW, Australia. Production from all phosphate rocks was low in the first year at both sites, but RPRs were similar to superphosphate by the fourth year. Production from RPRs was low in a dry year which is consistent with the requirement for moist acid soils for effective release of P from RPRs. Performance of RPRs was better at the site which was moister and had higher summer rainfall.
