Different standards

Some of the concentrations listed in Table 1 may be different to published standards from other parts of Australia or other countries. Some of these differences may be due to different varieties, or other factors such as soil type, planting time or method of fertiliser application.

For example, in the early growth stages the concentration of phosphorus (P) in the petioles needed for maximum growth of potatoes on the coastal sands is higher than for potatoes grown on heavier soil types, even for the same variety.

The concentration of nutrients in the petioles may also be higher during early crop growth, when all of a fertiliser is applied before planting compared with crops where most of the fertiliser is applied after planting.


Information on this page is based on work carried out in Project PT213 on fertiliser and irrigation management of potatoes, funded by Horticulture Innovation Australia, the WA potato industry and DAFWA.
