Sulphur Super 30 is made by adding molten sulphur to Superphosphate during its manufacture. This results in fine particles of elemental sulphur within the Superphosphate granule, which will oxidise in soil over approximately 12-24 months, depending on soil moisture content and soil temperature. Sulphur Super 30 contains 30.1% S, of which 21% is elemental S.
Although Sulphur Super 30 generally mixes well with other products, it is not compatible with the following:
Urea or Magnesium Oxide
Sulphur Super 30 can be compatible with the following under certain circumstances:
Flexi-N (magnesium coated Urea), Ammonium Sulphate Granular, Potassium Nitrate, Ammonium Nitrate, Mono Ammonium Phosphate (MAP), Cropmaster DAP or Calcium Ammonium Nitrate (CAN)
Segregation may occur when mixed with product with differences of particle size.
Refer to Compatibility chart.
Has both quick acting sulphate sulphur & medium term release elemental-sulphur
Used in a maintenance role where topdressings are infrequent
Used in a capital role where the requirement for Sulphur is much higher than for Phosphate
Particularly useful in areas where sulphate sulphur is prone to leaching and where phosphorus and elemental sulphur are required
Commonly used in the high country, and in low rainfall areas in eastern regions of both islands and certain high rainfall regions where excessive leaching may occur
Sulphur Super contains both quick acting sulphate sulphur and medium term release elemental sulphur which provides a longer lasting supply of nutrient to the soil. This is particularly important in areas where sulphate sulphur is prone to leaching and where phosphorus and elemental sulphur are required. The Sulphur Super range can be used in a maintenance role where topdressings are infrequent, or a capital fertiliser role where the sulphur requirement is significantly higher than the phosphate.
Sulphur Supers are commonly used in the high country, and in low rainfall areas in eastern regions of both islands and certain high rainfall regions where excessive leaching may occur.
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, Sulphur Super can be stored over a season as long as it is kept in a cool, dry, well ventilated area.
