METHOD OF PRODUCTION OF BIOFERTILISER Russian patent published in 2015 - IPC C05F3/00 C05F11/02 C05F15/00 C05F17/00 C05G3/00 

FIELD: agriculture.

SUBSTANCE: chicken manure and peat, taken in the ratio of 50:50, are shredded to particle-size composition of less than 10 mm. The shredded components are stirred and alkalified with 0.5% aqueous solution of potassium hydroxide in an amount of 1.5 l per 1 kg of the mixture at 20-22°C for 24 hours. Wheat bran is added into the resulting primary biofertiliser in an amount of 3 wt % and stirred. The first stage of the mixture bioconversion is carried out at 36-39°C for 96 hours. Then the second stage of bioconversion is carried out at 55-60°C for 24 hours. At that every 24 hours the mixture is purged with air in the longitudinal and transverse directions for 30 minutes.

EFFECT: increased efficiency of application by improving the survival of microorganisms, increase in biological activity of the soil, and improvement of consumer properties of the biofertiliser obtained.
