Fertilizer trials, which included rates of application of up to 400 kg ha-1 N, 200 kg ha-1 P and 200 kg ha-1 K, were established in experimental plantations of E. globulus at three sites in Gippsland, southeastern Australia. These sites cover a range of annual rainfall and soil fertility, from 620 mm on a deep infertile sand, to 1000 mm on a rich gradational clay loam. Early growth at all sites was significantly increased by the addition of fertilizers and by age 4 years was consistently best at the highest combined rates of N and P. Foliar N and P concentrations were significantly increased at all sites by combined additions of N and P at Age 1, but were insensitive to treatment at Ages 2 a..
