Abstract: Mycorrhizal and non‐mycorrhizal clover plants were grown in a sterilised phosphorus‐deficient soil, and fertilised with either pelleted Christmas Island ‘C’ grade phosphate rock or with powdered or pelleted Chatham Rise phosphate rock at eight rates ranging from 0 to 2.8 g fertiliser per pot. In a second experiment, ryegrass plants were fertilised with pelleted Chatham Rise rock phosphate. Mycorrhizal inoculation greatly increased shoot growth and phosphorus uptake compared to that of non‐mycorrhizal plants at fertiliser rates up to 1.4 g per pot. The recovery of phosphorus fertiliser from soil was generally low with maximum values of 11.3% and 17.2% in soil fertilised with pelleted Christmas Island and Chatham Rise rock phosphates and a maximum of 48.0% in soil fertilised with powdered Chatham Rise rock phosphate.
