Bio Boost Plus — this is a water solution containing bulbous bacteria Bradyrhizobium japonicum and Delftia acidovorans. The preparation is used in agriculture to increase crop yields by fixing atmospheric nitrogen. The biological preparation is applied as seed treatment or foliar spraying, which helps improve root system development and overall plant condition. The preparation contains viable bacterial cells at a concentration of not less than 2x109 CFU/ml for Bradyrhizobium japonicum and not less than 1x107 CFU/ml for Delftia acidovorans. This ensures effective interaction with plants, especially in rapeseed and soybean crops, where the bacteria facilitate nitrogen uptake from the air. Using Bio Boost Plus reduces the need for mineral fertilizers, making it an environmentally safe means to increase plant productivity. The preparation is suitable for use at various stages of vegetation and should be used according to the manufacturer's instructions.
