CALibrate Spring delivers available, plant-usable calcium in a foliar formula that is engineered to stay in the root zone and improve early-season nutrient flow, root function, and soil balance.
Non-leaching, stable formulation
Supports root health and early vigor
Improves cation exchange & nutrient flow
Buffers rhizosphere pH for biological activity
Delivers Immediately Available Calcium – No waiting for breakdown like lime or gypsum.
Stays in the Root Zone – Foliar-applied but engineered to bind in soil, not leach away.
Boosts Nutrient Uptake – Helps roots absorb nitrogen, potassium, and magnesium more efficiently.
Improves Early Root Growth – Activates soil biology and supports strong cell development.
Compatible & Fast-Acting – Mixes well with biologicals and starts working right away.
Available Phosphate (P2O5): 2%
Calcium (Ca): 27%
Derived from: Hydrated lime, calcium phosphate, coral powder
Apply 1 lb per 5 acres early season on your crop. Only available in 5 lb bags.
Price: $13/acre (at $65 per lb).
CALibrate Spring is compatible with most fertilizers, biologicals, and crop protection products but always jar test first.
CALibrate Spring is a targeted calcium solution designed to stay in the root zone throughout the growing season, delivering plant-available calcium exactly where it’s needed — when it’s needed.
