METHOD OF PRODUCING ORGANIC FERTILISER Russian patent published in 2012 - IPC C05F3/00 C05F17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture and can be used to process poultry droppings and pig manure. The method involves delivering components of the mixture to a platform with a solid coating, moulding two spaced-apart rollers from a water-absorbing agent at the platform, applying a layer of the water-absorbing agent and a layer of manure mass in the space between the rollers, selecting components of the mixture, mixing said components, stacking and subsequent natural composting of the obtained mixture. The water-absorbing agent used is chicken droppings with underlying material with moisture content 15-45%. The manure mass used is chicken droppings without underlying material with moisture content 50-75%. The components of the mixture also include pig manure with moisture content 70-96%. The layer of pig manure is placed on the layer of manure mass and said components are taken in weight ratio (0.9:1.2):(3.3:3.6):(1.1:1.4), respectively. Natural composting is carried out for not less than 30 days in the warm season and for not less than 90 days in the cold season. Initial heating of the mixture takes 7-10 days. During natural composting, the mixture is mixed at least twice. Composting is carried out in a pile.

EFFECT: invention enables to process chicken droppings with underlying material, chicken droppings without underlying material and pig manure into organic fertiliser, thus improving the environment when producing poultry and pig farming products.
