To test for field evidence for efficiency of fluid fertilisers.
Fluid fertilisers available in South Australia are relatively expensive compared with the granular fertilisers available. In early 2004, DAP and MAP were available on the Upper Eyre Peninsula at a cost of about $422/tonne delivered. The unit cost of P was $1.92/kg with MAP and $2.11/kg with DAP. In this case, any N combined with the P was supplied at no extra cost, with P the major limiting nutrient.
