Efficiency of Soil and Fertilizer Phosphorus Use: Reconciling Changing Concepts of Soil Phosphorus Behaviour with Agronomic Information

The efficient use of phosphorus (P) is essential to many agricultural and environmental issues. This bulletin reviews, analyses and synthesises information on the efficient use of soil and fertiliser P. It presents information on the plant availability of soil and fertiliser P, with an emphasis on soil plant interactions. The focus is on the changing concepts of the behaviour of both soil and P and on the need to define and assess their recovery and, thus, P-use efficiency more appropriately.
