The accumulation of animal and poultry waste poses a serious environmental hazard to the environment. One of the ways to eliminate it is the developed technological line for processing animal waste into organic fertilizers and preparations for agriculture and plant growing. The original peat-manure mixture must meet the following requirements - humidity 65-70%, the ratio of carbon to nitrogen - 20-25: 1, pH - 6-8. Controlled modes and parameters of the fermentation process form a high-quality, environmentally friendly fermentation product, which is used as a finished organic fertilizer. It is also possible to obtain a liquid-phase biopreparation from the fermentation product, characterized by a high level of biogenicity (total microbial number of at least 1 × 1010 CFU / ml) Extraction is carried out for two days for this purpose. The sediment formed after the separation of the extracted mass is characterized by a favorable composition and can either itself, after appropriate refinement, be used as an organic fertilizer, or be used as a raw material for obtaining a liquid humic preparation (the content of humic acids is at least 5 g / l, dry matter - not less than 17 g / l, pH 8-9) and humic paste (humidity 80-85%, the content of humic acids is not less than 20%, pH 12-13). Each product of the technological line has its own function for plant growing and agriculture. The technological line is waste-free, resource-saving; it is distinguished by the relative simplicity of production, the ability to scale and use regional raw materials.
