Ultrasol® Magnum P44

Ultrasol® Magnum P44 contains 44% P2O5, 17% N and free acid (H+) which makes it a unique product since it is the only dry, strong acid in crystalline form.

Thanks to its acidic action, Ultrasol® Magnum P44 increases the nutrient availability in the soil solution, improves the nutrient uptake efficiency, and helps to prevent the blocking of irrigation systems.
