Gypsum

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.

• 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.

• Calcium is vital for both plant and animal growth
• An essential part of the plant cell wall and membranes, aiding in plant structure and stability
• Earthworm activity is increased by the presence of calcium in the soil profile, therefore natural soil aeration is also increased
• Boosts soil microorganism activity, improving soil structure
• Calcium deficiency affects fruit crop quality and growth, and limits biological activity
• Calcium and magnesium work in synergy to promote stable soil structure
• Involved in the signalling of the availability of other nutrients (e.g. potassium), through its secondary messenger characteristics
• Assists in protecting the plant from biotic stresses
