Fertilisers

Serpentine Super is a magnesium-fortified superphosphate product, manufactured at our Mount Maunganui and Awarua plants. The phosphorus, sulphur and magnesium that it contains are readily available to plants, and the product is free of residual acid, which makes it suitable for use when fertiliser needs to be sown "down the spout" with seed. 

Serpentine Super 5K is blended with muriate of potash to create a general-purpose maintenance fertiliser that is ideal for use in a range of pastoral situations. The high proportion of citric acid-soluble phosphate in these products make them useful in conditions where phosphate run-off is a concern. The use of muriate of potash means these products are not suitable for use on chloride-sensitive crops.

Kieserite Granular is an excellent source of fast-release magnesium and sulphur, both of which are present in their water-soluble form. Kieserite Granular is particularly useful in alleviating acute magnesium deficiencies in high-value crops, for example, horticultural crops.

Manganese has a role in many important plant functions such as photosynthesis and is also needed for animal functions such as synthesis of cholesterol and glucose. Deficiency in grazing animals and pastures in New Zealand is rare.
