FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. The lime fertiliser for acidic soils and sodic soils is an ameliorant in form of defecation mud containing calcium carbonate. The defecation mud is filtration sludge from beet sugar production. The defecation mud used has chemical formula CaCO3+MgCO3 and is in form of a fluffy powder with particle size of up to 5.0 mm in amount of 45 wt % and contains 20 wt % organic substance and has moisture content of 20%.
EFFECT: invention increases yield of grain and tilled crops in the first half of the rotation cycle and also enables to obtain lime fertiliser with prolonged effect.
