This page outlines a general fertiliser program for fresh market winter and summer sown potatoes grown on coastal sands in Western Australia. This fertiliser program does not take into account nutrients applied to the crop in forms other than chemical fertiliser, such as organic amendments.
The recommendations cover the yellow (Karrakatta) and red-orange (Spearwood and Tuart) sands.
These fertiliser rates are a guide for fresh market potatoes, although adjustments may be required for specific varieties. The recommendations assume that the fertiliser is applied through the irrigation system (fertigation).
This information should be used in conjunction with other information on the fertiliser management of fresh market potatoes on sands. The program is designed to maximise returns and minimise environmental risk from leached fertilisers.
