Sulphur 90S

$595.00/t - Ex-Store

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.

Why Use Sulphur 90S?

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:

A slow release fertiliser consistently providing sulphate sulphur to the plant between annual applications.
Reduced sulphur leaching losses, ideal for soils with low anion storage capacity.
High analysis product reducing freight and application costs.
Easily blended with almost all fertilisers.

Product FAQs

When to Use

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.

Precautions

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.

Sulphur’s Role in Plants

Sulphur is essential in forming plant protein as it is present in cysteine and methionine, two vital amino acids involved in protein synthesis.
Key component of coenzymes and vitamins, involved in energy transfer and lipid synthesis.
Some sulphur compounds are responsible for the taste and smell of plants, like onions.
Sulphur amino acids are at high levels in animal fibres, therefore sufficient sulphur is required for good wool production.
Promotes nodule formation in legumes.
Signs of sulphur deficiency – light green to yellowish coloured young leaves, reduced plant growth rates, plants that are short, small and slender.
