Gypsum is a natural additive used in a variety of applications including as a carrier for horticultural dressings, as a mushroom composting ingredient, as a soil improver and in land reclamation after salt water flooding.
It is a source of calcium and sulphur for plant nutrition. It enhances soil aggregation and porosity to improve water infiltration (ability of the soil to drain), which promotes deeper rooting with benefits to the crops. It is also used to reduce the amount of erosion and of nutrients leaving farm fields after crops.
Natural additive with high purity and proven results
Particle size distribution adapted to agricultural applications
It can be used in organic agriculture
Provides a combination of calcium and sulphur in one application
Land that has been flooded by sea water or tidal rivers can be improved by treatment with gypsum, making it workable and fertile again.
SOIL TREATMENT / CONDITIONING
The direct application of gypsum improves the structure of clay soils and is often used in gardens and sports fields.
Many of the soil issues relate to its structure, for example due to compaction, erosion and reduced permeability.
Gypsum flocculation action helps soil aeration and therefore with water penetration, in particular in compacted or heavy clay soils, which will in turn promote healthy root growth and therefore will improve crop yield. It also assures structural stability in arable land, reducing the amount of work required upon it, especially in damp terrain.
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 .
Powdered and micronised gypsum can be used in fertilisers and horticultural dressings. Calcium sulphate anhydrite can also be used in fertilisers.
In general composting, gypsum provides a source of sulphur that can easily be assimilated by growing plants.
One particular area of application is the production of compost for mushroom growing. The flocculating action of the calcium sulphate helps the compost to maintain an open structure, preventing it from turning sour. It also provides a buffering effect that assists the compost in staying within a pH range of around six to eight. This ensures that chemically combined nitrogen levels are maintained.
