From P sorption curves a supernatant solution P concentration of 0.11 ppm corresponded to 90% maximum yield of field-grown tobacco. Nineteen virgin sites in the Mareeba-Dimbulah area were sampled to cover the range of major tobacco soils. Field application rates required for 90% maximum yield at each site were calculated from the P sorbed by the soil at a supernatant solution P concentration of 0.11 ppm. The rates were 5-43 kg P ha-1. Agricultural implications of these results are discussed.
