Complex microbial fertilizers (CMF) are an activated mixture of vermicompost and mineral concentrate, which is a substrate carrier consortium of soil microorganisms containing arbuscular mycorrhiza fungi, nodule and rhizosphere bacteria. CMF can be produced as granules or a fine particulate mass. One litre contains at least 100 million viable microbial cells. Pathogenic microorganisms, including Salmonella, are absent. The specific activity of man-made radionuclides Acs/60 + Asr/30 is not more than 1.0 RLU.

The role of CMF microorganisms:
The microorganisms contained in CMF restore the soil’s natural biological activity. In most cases, the land exploited for biogas production is in poor condition, and CMF develops the natural processes involved in converting organic matter into mineral compounds that plants find easily digestible.
In addition, bacterial and fungal cultures within CMF perform the following essential functions:
1. Increases the surface of plant root systems, which leads to a significant increase in their resistance to drought, frost and damage. This is achieved through the use of mycorrhizal fungi.
2. Increases the effective duration of fertilizers (helping reduce spreading frequency). This is achieved by the gradual processing of microorganisms within the soil’s organic matter, so that a uniform concentration of nutrients is maintained for longer.
3. Provides direct and indirect protection against moss due to the ability of microorganisms to actively counteract its appearance. CMF helps soil and plants prevent the generation of moss. Microorganisms also protect plants against plant pathogens and toxic substances decomposed in soil, thanks to the ability of CMF microflora to provide the necessary enzymes.
4. Improves the physical structure of the soil, contributing to porosity, which enhances the spread of nutrients in the air and water, thereby obviating the need for regular aeration. The effect is achieved through the ability to attract active soil microflora, such as annelids.
5. Ensures residue is processed fast, within a few days. This eliminates the need for clearing and waste such as grass clippings is turned into nutritional biomass, which serves as an additional fertilizing agent.
6. The organic mass within CMF provides replenishment for the soil over the lifecycle of plant minerals and nutrients.
