FIELD: fertilizers. SUBSTANCE: invention relates to a method of lake sapropelic slime output. Method involves rising the sapropelic deposit from the bottom at the natural moisture 95-98% by centrifugal ground pump fitted on the hydraulic dredge being with the preliminary loosening bottom deposits, pulp hydrotransporting by pulp tubes into hydrodump-settlers, preliminary dehydration, pumping out settled water back to lake, loosening the upper layer by cutting ripper, drying. Preliminary dehydration is carried out up to moisture 35% and drying - to moisture 12-15%. Filtration capacity of sapropelic mass is increased by 3-4-fold. EFFECT: decreased water-absorption, improved quality of sapropel.
