Abstract
A glasshouse trial with wheat (Triticum aestivum L. cv. Gamenya) in which harvests were taken at intervals up to 24 days has shown that the effectivness of calcined Christmas Island C-grade aluminium-iron phosphate rock (C500) relative to superphosphate remained low. Relative growth rates did not change despite a decrease in the concentration of bicarbonate extractable phosphorus in soil fertilized with superphosphate. Different numerical values of relative effectiveness based on plant yield and phosphorus uptake respectively may be attributed to different internal efficiencies of phosphorus use for the two fertilizers.
