Hi-Cal Lime Powder – 50 lb Bag
This premium 100% pulverized limestone is a finely milled, fast-reacting high-calcium lime that provides 38% elemental calcium and 95% calcium carbonate equivalent (CCE). With extremely low magnesium content, it's the ideal choice for raising soil pH and supplying bioavailable calcium without altering soil magnesium ratios. The fine mesh size ensures rapid reactivity, making this a powerful amendment for acidic soils in vegetable beds, pastures, orchards, and regenerative systems.
Key Benefits
-
High-Calcium, Low-Magnesium Formula
Contains 38% elemental calcium and virtually no magnesium, making it ideal for correcting calcium deficiencies without compounding magnesium imbalances—especially in tight or clay-heavy soils. -
Fast-Acting and Finely Milled
With 97% passing through a 100 mesh and 85% through a 200 mesh screen, this lime is highly reactive and begins adjusting soil pH quickly once incorporated into the soil. -
Raises Soil pH and Enhances Nutrient Uptake
The 95% CCE means this lime is extremely effective at neutralizing acidic soils, unlocking nutrients, and improving overall soil biology for crop health and vigor. -
Reliable for Soil Remineralization in Organic Systems
Ideal for growers focused on mineral balance and long-term soil health without synthetic inputs. Use for garden beds, row crops, food forests, and pasture improvements. -
Versatile Across Growing Systems
Best applied in fall or early spring; can be tilled in, blended with compost, or used in surface applications in low-till systems.
