Sulphur 90S is a pastille made up of 90% fine particle elemental sulphur and 10% bentonite. The elemental sulphur in the granule is oxidised by soil microorganisms over time into sulphate sulphur where it is then made plant available and taken up by plants. Bentonite is added to the granule to improve the break down and dispersal of the sulphur.
Sulphur 90S is oxidised by the soil into plant available sulphate sulphur. This ongoing mineralisation consistently provides plant available sulphate to the plant, satisfying the majority of plant sulphate requirements over a 1-2 year period. Resulting in improved utilisation and responses, compared to one-off larger applications of sulphate sulphur which can be quickly leached through the soil profile leaving the soil sulphur deficient for large periods of the year.
Benefits of Sulphur 90S:
Blend Sulphur 90S with capital and maintenance applications. Sulphur 90S only needs to be applied once per annum as a result of its slower releasing characteristics.
It can be advantageous to substitute 90S with sulphate sulphur in the wetter/cooler months when the rate of mineralisation of elemental sulphur is low.
