A SYSTEMATIC APPROACH TO THE FORMATION OF QUALITY AND ENVIRONMENTAL SAFETY OF BIOFERTILIZER FROM DIGESTATE
The use of anaerobic digestate as a biofertilizer is quite promising in terms of soil protection technologies in view of the reduction of environmental risks from the use of mineral fertilizers and the positive impact on soil productivity, improvement of their quality and restoration of the humus layer. However, anaerobic digestion does not ensure the complete absence of environmental hazards due to a certain probability of heavy metals, pharmaceutical substances, and pathogenic microorganisms entering the soil with biofertilizer.
