METHOD OF PRODUCING BIOLOGICAL FERTILISER Russian patent published in 2016 - IPC C05F3/00 

FIELD: agriculture.

SUBSTANCE: method of producing organic fertilizer includes preliminary milling of chicken excrement and peat, taken in ratio 50:50 to grain size of not more than 10 mm with subsequent stirring and alkalinity of 0.5% aqueous solution of potassium hydroxide in amount of 1.5 l per 1 kg of mixture at temperature 20-22°C during 24 hours, adding the obtained primary biological fertiliser wheat bran in an amount of 3 wt% mixture with subsequent stirring of components and conducting the process bioconversion in two steps at high temperature Note here that first stage bioconversion is carried out in temperature range 36-39°C during 96 hours, second-in temperature interval of 55-60°C during 24 hours, during bioconversion mixture is periodically blown air in longitudinal and transverse directions for 30 minutes every other 24 hours, simultaneously with wheat bran in primary biological fertiliser potassium tartrate is introduced in an amount of 0.1 wt% of mixture and citric acid in amount of 0.1 wt% of the mixture.

EFFECT: invention allows to produce a new biological fertiliser, enriched with potassium-sodium tartrate and citric acid, providing effective action on plants growth and development.
