Top 10 Companies in the Calcium Sulfate for Agricultural Use Market (2026): Market Leaders Driving Global Soil Health

MARKET INSIGHTS

Global calcium sulfate for agricultural use market size was valued at USD 765.4 million in 2024. The market is projected to grow from USD 821.7 million in 2025 to USD 1.42 billion by 2032, exhibiting a CAGR of 7.1% during the forecast period.

Calcium sulfate, primarily used in agriculture as gypsum, is a versatile soil amendment that improves soil structure, enhances water infiltration, and provides essential calcium and sulfur nutrients. It plays a critical role in neutralizing soil alkalinity, reducing sodium toxicity, and promoting root development. The compound is available in various forms, including powder and granular, tailored for different agricultural applications.

The market growth is driven by increasing awareness of soil health management, rising demand for high‑yield crops, and sustainable farming practices. However, fluctuations in raw material prices and regional supply chain disruptions pose challenges. Key players like ACG Materials, GYPSOIL, and Lafarge are expanding production capacities to meet growing demand, particularly in North America and Asia‑Pacific, where agricultural modernization is accelerating.
