The effect of the method of production a new fertilizer containing Streptomyces coelicolor grown on whey on its effectiveness

Relevance. In recent years, we have seen an Increase In the number of new bacterial fertilizers. New fertilizers must be effective, so it is important to select their qualitative and quantitative composition. It is equally important to study the effect of these bacteria on their number, dissemination and long-term residence in the soil, as well as their effects on plants. Aim of the Study. This work studies the effect of the method of obtaining a fertilizer containing Streptomyces coelicolor grown on the whey on the amount and duration of these bacteria in the soil and on the growth characteristics of white mustard (Sinapis alba L.) sown into the soil after a long time after watering with fertilizer.
