FIELD: agriculture.
SUBSTANCE: method for obtaining an ameliorant for acidic soils from nepheline sludge includes its preparation in a slurry storage and subsequent drying in air to the humidity of 25%. The nepheline slurry is additionally subjected to grinding in a ball mill to the coarse size of 55-60% of the class - 0.074 mm.
EFFECT: invention allows to increase the deacidifying ability of the ameliorant and to reduce its consumption.
