Biohumus was produced in harmony with nature. In the natural environment, many processes take place that break down dead organic matter. This phenomenon is called the circulation of matter. It is thanks to this process that the elements in the soil used by plants are constantly replenished. Soil macro- and microorganisms contribute to the decomposition of dead organic matter. Such a macroorganism is the commonly known California earthworms, which by digesting food enrich it with useful soil microorganisms. For the production of biohumus, we use the potential of California earthworms that process organic substances in a natural way. The substance obtained in this way is active humus, which, released for a long time, ensures constant nutrition of the plants.
