Overview
Calcium Products makes calcium-based fertilizers, especially pelletized limestone and gypsum, for farmers and turf managers. It buys and processes pure limestone to create products that raise soil calcium and adjust pH, helping soil structure and nutrient availability so crops and turf can grow better. The pellets are designed for easy spreading and even distribution, making soil conditioning simpler for growers. The company differentiates itself through its focus on high-purity limestone sources and a long history of soil-health work, plus a track record of expanding its sales and operations under different ownership groups. Its goal is to improve soil health and crop yields by delivering reliable calcium-based soil amendments at scale, and to grow by incorporating agtech approaches and broader distribution under its current leadership.
