FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. Method of obtaining biomineral fertilisers includes combination of dry or liquid mineral fertilisers and meliorants with microbial biomass; in the first version as microbial biomass used is microbiological fertiliser or preparation, created on the basis of agronomically useful microorganisms in form of dry fine-disperse powder with titre 102-105 kl/g, which is applied on dry mineral fertiliser or meliorant or introduced into liquid mineral fertiliser in dose 2-6 kg/t; in the second version, as microbial biomass used is microbiological fertiliser or preparation, created on the basis of agronomically useful microorganisms in liquid form with titre 104-107 kl/g, which is applied on dry mineral fertiliser or meliorant by fine-disperse spraying or is introduced into liquid mineral fertiliser in dose 1-4 kg/t.
EFFECT: invention makes it possible to increase efficiency of application of introduced into soil mineral fertilisers by crop plants to increase their productivity.
