Potassium is one of the essential macro-elements required by the plants. DAYAN Petas Bacter® contains potassium solubilizing bacteria that are capable of decomposing feldspars, mica, silicates, and other mineral resources and, releasing the potassium element accessible for plant uptake. In addition, these microorganisms not only decompose potassium sources to release potassium but also produce organic acids, enzymes, and beneficial microbial metabolites which all together increase the crop yield and resistance to abiotic and biotic stressors. This product has been developed using exclusive active species of Bacillus sp. and Pseudomonas sp. with high potassium solubilizing properties. This product could partially provide the potassium requirement of plants through solubilizing insoluble potassium sources present in the soil.
