Moody, P.W., Dickson, T. and Aitken, R.L. (1997) Soil phosphorus tests and grain yield responsiveness of maize (Zea mays) on Ferrosols. Australian Journal of Soil Research, 35 (3). pp. 609-614. ISSN 0004-9573

The grain yield response of maize (Zea mays) to various rates of applied phosphorus (P) was measured at each of 17 sites in the South Burnett region of south-eastern Queensland. The soils at all sites were Ferrosols. Relative grain yield of the nil applied P treatment [100 × (yield at nil applied P/maximum yield)] was related to Colwell (0·5 M NaHCO3) extractable P (PB), CaCl2-extractable P, and equilibrium P concentration and P buffer capacity calculated from P sorption curves. Of these P measurements, PB was most highly correlated with relative grain yield (R2 = 0·94 for a linear response and plateau fit, R2 = 0·92 for a Mitscherlich fit), and the PB values at 90% maximum grain yield were 20 mg/kg for the linear response and plateau model and 32 mg/kg for the Mitscherlich equation.
