High-Quality Gypsum

Versatile Mineral for Agriculture, Construction & More

Our premium gypsum is a reliable, high-purity mineral compound renowned for its diverse applications across multiple industries. Mined from top-grade sources and meticulously processed, it ensures the consistency and quality you need for everything from agriculture to construction.

Agricultural Benefits

Gypsum is widely used in agriculture to enhance soil health, boost crop yields, and address specific soil deficiencies.

  • Soil Amendment: Improves soil structure by breaking up heavy clay soils, promoting better drainage and root penetration.
  • Sodic Soil Reclamation: Replaces excess sodium with calcium, restoring soil fertility and structure in sodic soils.
  • Nutrient Source: Provides essential calcium and sulfur, supporting cell wall strength and protein synthesis in plants.
  • pH Adjustment: Helps neutralize alkaline soils, improving nutrient availability and overall soil fertility.
  • Alleviating Soil Toxicity: Reduces aluminum and manganese toxicity by aiding in leaching and preventing harmful uptake by plants.
  • Improved Drainage & Erosion Control: Enhances water infiltration, reduces runoff, and helps minimize soil erosion.
  • Improved Soil Structure & Water Relations: Encourages better aeration, higher water retention, and healthier root development.
  • Increased Earthworm Population: Fosters an environment conducive to beneficial earthworms, further enriching soil structure and nutrient cycling.

Application Rates & Methods

Proper application of gypsum depends on soil type, crop requirements, and your specific agricultural goals. Below are general guidelines. Always perform a soil test to determine exact needs.

Soil Amendment

Soil Type Application Rate Purpose
Heavy Clay Soils 1–2 tons/acre (2,000–4,000 kg/ha) Improve soil structure & drainage
Sodic Soils 2–4 tons/acre (4,000–8,000 kg/ha) Reclaim soils with high sodium

pH Adjustment

Soil Condition Recommended Rate Notes
Alkaline Soils 500–2,000 lbs/acre (560–2,240 kg/ha) Adjust based on soil tests & buffering capacity

Nutrient Source

Rates may vary based on crop nutrient requirements and existing soil fertility. Use gypsum to ensure adequate calcium and sulfur supply, especially for crops prone to these deficiencies.

Maintenance & Timing

  • Ongoing Application: Annual or periodic applications may be beneficial, depending on crop rotation and soil test results.
  • Broadcast or Incorporate: Gypsum can be broadcast on the soil surface or incorporated pre-planting. Light incorporation improves distribution and effectiveness.
  • Monitor Soil: Regularly test your soil and adjust gypsum applications as needed.
  • Regulatory Compliance: Follow local best practices and guidelines to minimize environmental impact.

Construction Industry

  • Drywall & Plasterboard: Essential for producing fire-resistant, soundproof interior walls and ceilings.
  • Mortar & Cement: Added to regulate setting times and improve workability.
  • Gypsum Blocks & Panels: Lightweight, mold-resistant materials for interior partition walls and decorative elements.

Industrial Applications

  • Construction Materials: Gypsum-based products like plaster, joint compounds, and grouts.
  • Paper Manufacturing: Used as a filler and coating agent to enhance paper strength and printability.
  • Textile Industry: Employed in sizing and finishing processes to impart stiffness and improve dye uptake.

Environmental Remediation

  • Water Treatment: Aids in removing turbidity, heavy metals, and phosphates.
  • Air Pollution Control: Used in flue gas desulfurization (FGD) systems to capture sulfur dioxide emissions.

Art & Crafts

  • Sculpture & Molding: Fine-grained texture and easy carving make gypsum ideal for artists.
  • Model Making: Commonly used in architectural models, dioramas, and hobby crafts due to affordability and workability.

Frequently Asked Questions

How often should I apply gypsum?

Typically once a year or as recommended by a soil test. This ensures your soil maintains optimal structure and nutrient balance.

Will gypsum raise my soil’s pH?

Gypsum helps amend alkaline soils but does not significantly alter soil pH when used in moderate rates. It primarily addresses sodium issues and supplies calcium and sulfur.

Is gypsum safe for organic gardens?

Yes, gypsum is generally approved for use in organic farming. However, always verify with your specific certifying agency to ensure compliance.

The Gypsum was spread thin and worked into the garden soil as a sidedressing. Blossom rot vanished and the next set of veggies and fruits to ripen were scrumptious.
