Characteristics and effect of application. Fast and complete water solubility. Excellent concentrated source of phosphorus and potassium for fertigation and sheet feeding. The absence of nitrogen makes it possible to use IQR in all vegetable growing systems, including at the ripening stage. It helps to reduce plant damage by fungal diseases (powdery mildew, etc.). Contains no impurities - salts and ions of heavy metals It has low electrical conductivity, and therefore does not create problems in saline and alkaline soils. The risk of burning and twisting leaves for leaf feeding is very small, which allows the use of fertilizer in high concentrations. Phosphorus remains in solution and remains stable even at pH 4.5. Increases the mobility of elements in the soil, stabilizes the tank mixture and increases the effectiveness of pesticides.
