Rootphos Acid 7-21-0
Phosphate is an essential macronutrient and it has several key roles in crop production. Phosphorus is essential for ATP, ADP, and basal metabolism within plants. Phosphate solubility and availability can be affected by things like pH or excess lime. In high pH soils with excess lime, phosphate can react with cations like calcium, making it insoluble and unavailable. Rootphos Acid 7-21-0 + Zn is an acid base phosphate solution that can be used in hard water situations to help prevent precipitation and that helps keep phosphate soluble and available.
