FIELD: chemistry, agriculture.
SUBSTANCE: method includes extraction of sapropel from lake, mixing it with natural organic filler, as such dried crushed peat with particle size up to 100 mcm and humidity up to 10% is used. Extracted from lake sapropel with natural humidity is mixed with said dried and crushed peat, taken in amount determined by formula: 
where Wnp is set humidity of fertilizer to be obtained, %, Wc is natural humidity of extracted sapropel, %, Wa is peat humidity, %, Qc is volume of sapropel with natural humidity, supplied per a unit of time, in m3/min, Qa is volume of peat, supplied per a unit of time, in m3/min until final product is obtained with set humidity.
EFFECT: invention will allow to obtain high-quality fertiliser with stable properties and regulated humidity with acceleration of technological process.
