Metalosate® Calcium Boron is an amino acid chelated calcium and boron fertilizer formulated for foliar application to prevent or correct calcium and boron deficiencies that limit crop quality and yields. Produced by Balchem (Albion Plant Nutrition), it is fully water soluble, nontoxic to plants when applied as directed, and certified for use in USDA organic programs via third-party verification.

• Superior Foliar Absorption — Amino acid chelation improves Ca and B uptake through leaf tissue versus inorganic sources
• Fully Water Soluble — No residue; compatible with most foliar spray programs
• USDA Organic Certified — Meets rigorous organic certification standards via third-party verification
