Abstract

Phosphorus (P) is a significant annual fertiliser input for crop production in southern NSW. The extensive history of P application and mostly adequate to high soil Colwell P values in this region allow many farmers some flexibility in managing P inputs, particularly where cash flow may be limited. The flexibility in P management is also made possible as crop uptake of P is primarily from the soil reserve with a smaller but important component coming from starter P applied at sowing. In this paper we discuss both P considerations after drought and P cycling and uptake.
