SoluProteK is designed to have a distinct nutritional effect and to strengthen the natural defenses of plants. In addition to preventing and treating nutritional deficiencies, the presence of potassium and phosphorus (in the form of highly absorbable phosphite ion) stimulates the plant to produce large amounts of natural defensive substances. These substances, called phytoalexins, create unfavorable conditions for the development of fungi and bacteria. Moreover, Nitro Force Plus PK improves the lignification of buds, as well as flowering, the fruit set stage, fruit size and shape, colouring, the fruit’s preservation properties, and the fruit’s sugar content. Nitro Force Plus PK encourages systemic activity in plants, both in bottom-up and top-down directions, as it is easily absorbed through the leaves, branches, and roots. Therefore, this product is suitable to be used in foliar application and in fertigation. The mix with fungicides, insecticides, herbicides, chelates, etc., promotes the absorption and distribution of this product thanks to the combined effect of the fertilizer with other substances.
