Lime for turf. Rock for landscape.

Calcium carbonate for turf soil pH management, plus crushed landscape rock and decorative grades from the same Idaho deposit, screened to size.

Turf, sports fields and landscape beds rely on soil pH for nutrient availability. Calcium carbonate from our Idaho deposit is used to raise the pH of acidic soils; the rate and grade follow a soil test and the turf manager’s program.

Fine grades react quickly and suit spreading on established turf; coarser grades break down over a longer period. Our team can help match particle size to the equipment, the schedule and the soil.

Every load leaves with a load ticket and certificate of analysis. Turf and landscape contractors can plan standing orders around the season.
