Buystar Extra NPK 10-50-10 is a microcrystalline fertigator characterized by total and immediate solubility, by a high Phosphorus content and by the presence of RyZea, a natural biological activator that enriches the formulation of components capable of enhancing plant metabolism, soil-based processes and the nutritional value of the circulating solution. High levels of phosphorus are important in stimulating root growth, flowering and fruit swelling. Furthermore, Phosphorus increases the robustness of plant tissues, especially herbaceous crops, making plants less susceptible to harmful agents.
