Description
Gypsum (calcium sulfate dihydrate) adds calcium and sulphur to soil without raising pH. It reduces soil compaction and helps correct soils with high sodium concentrations. Our gypsum delivers exceptional purity. We mine it away from metro areas to ensure low heavy metal content and consistent quality.
You can use gypsum to improve soil structure in both open-field and container growing. It flocculates clay particles, improves drainage, and increases water infiltration. As a result, roots penetrate deeper, oxygen moves more freely through the root zone, and plants establish faster. In sodic soils, calcium from gypsum replaces excess sodium on the cation exchange sites. This process improves soil aggregation and restores productive growing conditions.
Gypsum’s Main Elements
The Calcium in gypsum strengthens plant cell walls and membranes. It helps plants withstand stress from pests, disease, and drought. Calcium also supports enzyme production and drives overall plant health and structural integrity. Because gypsum does not alter soil pH, you can apply it confidently where you need calcium without disrupting your nutrient balance.
Sulphur drives the production of key amino acids, proteins, and enzymes. It directly influences vegetative growth and yield. Sulphur improves nitrogen efficiency, supports oil production in oilseed crops, and enhances flavour and aroma in many fruits and vegetables. Strong sulphur levels often translate into better crop quality and higher market value.
Gypsum Typical Analysis:
Calcium as Ca – 26.8%
Calcium as CaSO₄·2H₂O – 90.3%
Sulphur as S – 21.6%
Sulphur as SO₃ – 42.0%
CCE (HCl) – 3.0%
Magnesium as Mg – 0.24%
Silicon as SiO₂ – 6.0%
Sodium as Na₂O – 0.2%
Gypsum Application Rates:
Potted Plants – 1–2 Tbsp per 20L substrate
For larger production systems, test soil phosphorous levels before application. Use the results to determine accurate rates. Conduct follow-up soil analysis after application to track improvements and adjust your fertilisation plan.
