Most soils used for agriculture in Western Australia had insufficient indigenous native phosphorus P for the introduced agricultural plant species used in the region so fertiliser P had to be applied. This bulletin covers how water-soluble P WSP fertilisers are made, and how the P in the fertilisers dissolves and reacts with soil in the year of application and in the years after application, how soils sorb P and procedures and soil tests used to estimate the capacity of soils to sorb P.
