Ammonium polyphosphate (APP) was compared to ammonium orthophosphate (AOP) with successive crops grown on four calcareous soils in the greenhouse. Barley ( Hordeum vulgare ) the first crop, responded to P on three of the soils, with AOP superior to APP on two soils. With tomatoes ( Lycopersicon esculentum ), the second crop, APP was significantly better than AOP on all soils. APP was a satisfactory P source and was superior to AOP for the second crop.
