| Physical description |
Physical Description Superphosphate is made by reacting finely ground phosphate rock with sulphuric acid to convert the insoluble mineral to a plant available form. Superphosphate contains phosphorus and sulphur in a ratio of 1 to 1.22. When applied at a rate to meet P requirements, the sulphur requirements will also be met in the majority of situations. The colour varies from brown to dark grey with each rock type. |

Cost effective fertiliser for pasture development
Ideal for capital or maintenance applications
Readily available phosphorus and sulphur
Superphosphate contains Sulphur in a readily available form of sulphate for plants to take up. This makes it ideal for low fertility and cropping situations
The Calcium in Superphosphate can be important in some horticultural and hill country situations where it is uneconomic to use lime
Uses
Superphosphate is an ideal fertiliser for capital or maintenance applications. It is mainly used as a maintenance fertiliser, providing a pool of soil solution P for pasture. It is also ideal for pastoral development and arable/horticultural situations where immediate responses are required.
Application rates and advice
It is recommended not to be spread at rates of over 1 tonne/ha. Actual spreading rates will vary according to farm type, climate, productivity and soil type. Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate. Call our Customer Centre for information.
As with most solid fertilisers, Superphosphate can be stored over a season as long as it is kept in a cool, dry, well ventilated area.
