Introduction
Fertiliser practices in Europe have been identified as an important factor contributing to the contamination of ground water with nitrates. A shortage of sulfur (S) lowers the utilisation of applied nitrogen (N) fertiliser (Ceceotti 1996) because both S and N are required for the synthesis of plant proteins. In Western Australia, on poorly sorbing sandy soils, there has been a similar problem with the inefficient use of phosphorus (P) in the absence of adequate sulfur contributing to the leaching of the phosphorus from sandy soils into waterways and causing algal blooms. Soil testing has shown that P applications are often greatly in excess of ...
