    Product Overview

    Agricultural-grade gypsum (calcium sulphate dihydrate) for sodic soil reclamation, calcium supply, and structure improvement across Oman's irrigated farmland.

    Detailed Description

    Agricultural Gypsum (CaSO4·2H2O) is the workhorse soil amendment for reclaiming sodic and saline-sodic soils across Oman's irrigated regions — a common problem where saline groundwater raises exchangeable sodium and destroys soil structure. Gypsum supplies soluble calcium that displaces sodium from the cation exchange complex, restoring aggregate structure and water infiltration. Also a non-acidifying calcium and sulphur nutrient source (23% Ca, 18% S) for peanuts, alfalfa, and forage crops. Global Chemicals LLC supplies mined agricultural gypsum in 25 kg bags and 1,000 kg big bags.

    Frequently Asked Questions — Agricultural Gypsum (Calcium Sulphate)

    Global Chemicals LLC supplies agricultural-grade gypsum (calcium sulphate dihydrate, 23% Ca, 18% S) in 25 kg and 50 kg bags with bulk tonnage for farm-scale reclamation projects. Same-day Muscat dispatch; delivery across Oman's agricultural regions and GCC export on request. CoA confirms purity and particle size on every lot.

    Typical reclamation rates run 2–10 t/ha depending on exchangeable sodium percentage and soil texture — a soil test converts ESP to a precise gypsum requirement. Apply, incorporate into the top 15–20 cm, then leach with good-quality irrigation water. For maintenance of irrigated ground under saline water, annual rates of 0.5–2 t/ha are common. Send us your soil analysis and we'll calculate the tonnage.

    Pricing depends on volume, bag size and delivery zone — bulk farm-scale tonnage prices substantially below bagged retail. Request a quote with your tonnage and location; we respond with delivered pricing the same business day.
