High Quality Agricultural, Landscaping, and Highway Products Using Specialty Minerals Ground Calcium Carbonates

Calcium carbonate and dolomite are suited to a wide variety of agricultural applications, including pH control, fertilizer conditioners and fillers, and animal feed formulations. Architectural and landscape uses include decorative stone for landscaping, golf course applications, and athletic-field line marking.

Agricultural requirements for crop production target specific pH ranges for soil to optimize production, reduce blossom end rot on tomatoes, and facilitate development of mushroom spawns. Soil-application products can be designed for field spreading or can be pulverized for drip irrigation use. 

Calcium carbonate also is important in animal nutrition. Calcium supplements for cattle and other livestock play a key role in bone growth and strength as well as in general animal health. Poultry require grit in the gizzard to assist with digestion and strengthen shells for proper egg production. Calcium carbonate is also used as a fortifier in pet foods and animal nutritional supplements.

Architectural applications include premium trap sand for golf courses and beautiful, white crushed limestone and dolomite for decorative rock and landscaping.  

Chemical purity, brightness, and consistency play a major role in the end value for the application. Specialty Minerals Inc. (SMI) is well positioned to supply you with our standard products or work with you to develop new products tailored for your applications.
