Abstract
Growth of Radiata pine on a strongly P-fixing soil in south-eastern Australia was severely limited by P deficiency. Phosphate fertiliser was applied at rates of 0, 60, 90, 120, 180 and 240 kg P/ha as split applications at age 4 and 7 years to determine the response in growth and changes in tree nutrient status. Application of at least 120 kg/ha was required to increase the rate of growth from 15 to 31 m3/ha/yr and to improve total volume by approximately 370 m3/ha at age 22 years. Growth response to fertiliser over the 18 year period was strongly correlated with levels of P in foliage 4 years after treatment. At 22 years, trees were again deficient in P indicating the need for another application of fertiliser to maintain growth over a 35 year rotation.
