Polyphosphate · Potassium, Calcium and Magnesium is one of the core products jointly developed by Agadi Australia Limited and the University of New South Wales in Australia. It uses the internationally leading polyphosphate chelation technology to produce polymerized medium and micro elements, rich in organic oligopeptides, algal polysaccharides, calcium, magnesium, phosphorus and potassium, and other large, medium and micro elements. Through polyphosphate technology, the problem of mixing multivalent phosphorus and calcium is perfectly solved, Greatly improving the mobility and absorption rate of phosphorus and calcium, with strong stability, effectively regulating the calcium magnesium ratio in the working object; Collaborate with the absorption of calcium, magnesium, phosphorus, and potassium elements by crop roots, stems, leaves, and fruits, mutually enhance and improve utilization efficiency, achieving the effects of exploding roots, strengthening stems, green leaves, and expanding fruits.
