    Can Phosphorus Be Tank Mixed with Calcium? With Nova PeKacid®, the Answer Is Yes. 

    Traditionally, calcium and phosphorus are not tank mixed. Under typical conditions, they react to form insoluble calcium phosphate—risking clogged systems and tying up nutrients in forms unavailable to the plant. Not with PeKacid.

    Why Is Nova PeKacid Different? 

    Nova PeKacid’s patented low pH formulation changes the calcium-phosphrous interaction, helping keep phosphorus soluble and available—even in the presence of calcium and magnesium. 

    What this means in practice: 

    • Low pH conditions enable tank mixing with calcium and magnesium fertilizers  
    • Neutralized bicarbonates without reliance on nitric acid (and risk of excess nitrogen)  
    • Supplies readily available orthophosphate and chloride-free potassium  
    • Provides greater nutritional flexibility, allowing calcium and magnesium applications alongside phosphorus to better meet crop demand  
    • Acidifies the root zone, enhancing nutrient availability and uptake  

    Nova PeKacid Compatibility notes: Avoid mixing with thiosulfate-based products or chelated micronutrients.
