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. However due to granule size consistency we would not recommend for precision drills.
