To investigate responses to phosphorus (P) fertiliser of common wheat and barley varieties on a P deficient soil
At low available soil P and moderate PBI levels relatively high P inputs are required to maximise yields. Replacement P programs should incorporate a measure of PBI in order to effectively balance available P across different soil types. Significant yield differences between varieties of wheat and barley could not be attributed to varying P uptake efficiencies
