Calphos

Mined soft phosphate supplying phosphorus and calcium to the soil.

What is it ?

Calphos is a soft phospate for adding phosphorus and calcium to soil. Soft phosphates are typically a product of mine tailings that have been processed from clay-rich soils also rich in marine fossils. It is not acid forming and is designed to prevent hardening making it easy to spread. It is resistant to leaching, providing a long-term source for these nutrients, yet generally more soluble than hard rock phosphates.
