Drone-Grade Monopotassium Phosphate is a high-purity water-soluble fertilizer specially developed for agricultural UAV spraying and precision foliar nutrition. Its flash-dissolution technology ensures rapid dissolving and very low insoluble residue, effectively reducing nozzle-blockage risk. Supplied as a fine white powder with concentrated P and K, the formulation contains a functional synergist that improves wetting, spreading and adhesion on leaf surfaces, reducing spray loss and enhancing foliar uptake. Suitable for drone spraying and foliar application on wheat, rice, maize, vegetables and fruit trees.
