Gypsum

Gypsum (Calcium Sulfate) – Soil Conditioner and Nutrient Source

Natural Amendment for Better Soil Structure and Calcium Supply

Gypsum, or Calcium Sulfate, is a widely used soil amendment that provides two essential secondary nutrients: Calcium and Sulfur. Unlike lime, Gypsum can improve the physical structure of heavy or clay-rich soils by helping soil particles bind together (flocculation), which drastically improves water infiltration, air movement, and drainage without affecting the soil’s pH level.

Key Benefits

• Improves soil structure, aeration, and drainage in compacted or clay soils.
• Provides readily available Calcium, essential for cell wall strength and growth.
• Supplies Sulfur, critical for protein synthesis and enzyme activity.
• Helps leach excess sodium from the soil, especially after using hard water.

Composition & Specs

• Material: Calcium Sulfate Dihydrate (CaSO₄·2H₂O).
• Function: Soil conditioner, Ca and S fertilizer.
• pH Impact: Negligible change to soil pH.

Usage Tips

• Broadcast and incorporate into the topsoil prior to planting.
• Use to treat salty soils or areas that suffer from poor drainage.
• Can be mixed into potting soil or coco coir for supplementary Calcium.

Gypsum is a foundational amendment for enhancing physical soil health and supplying key nutrients for plant vigor.
