Fertiliser
Used as a fertiliser for over 250 years providing crops with the required levels of essential nutrients, calcium and sulphur, improving overall plant growth
It is used as an additive and carrier in fertiliser preparations.
Fertilisers may be needed in soil for a number of reasons, including humus deficiency, incorrect crop rotation and specific requirements of a particular crop. They may be required due to the geological origin of the soil. Gypsum provides both the sulphur and calcium that are indispensable elements for the process of fertilisation . Its value as a fertiliser for leguminous crops was widely recognised since the nineteenth century.
Powdered and micronised gypsum can be used in fertilisers and horticultural dressings. Calcium sulphate anhydrite can also be used in fertilisers.
Benefits of usage
- Provides a combination of calcium and sulphur in one application
- Encourages the development of larger root growth. Due to the lower solubility of calcium sulphate versus other alternatives, progressively liberates the sulphur and also the calcium, which can be directly assimilated by plants.
- Gypsum will lower the pH of acidic soils and assists in the assimilation of nitrogen.
