The utility model is based on the task of improving the composition of an organic-mineral mixture to the level of a complex fertilizer as a plant growth and development stimulator and a plant protection agent against bacterial and fungal diseases.

The problem is solved by the fact that there is known a mixture containing an organic component from the group: leonardite, lignite, peat or a mixture of any of these substances, and a mineral component, containing a mineral component selected from the group bentonite, trepel, glauconite, or a mixture of any of these minerals and/or rocks, wherein the organic component constitutes 70-80 wt% of the dry mixture, and the mineral component constitutes the remaining wt% of the dry mixture, and is enriched by the introduction of nitrogen-fixing, phosphorus- and potassium-mobilizing, bactericidal and fungicidal bacterial microflora. These features are essential features of the utility model. In order to create a favorable environment for bacteria, it is advisable to use organic and mineral components of the complex fertilizer crushed to a fraction of 150-100 microns
