FIELD: technological processes.
SUBSTANCE: invention relates to production of ameliorants and can be used in agriculture to reduce soil acidity. As lime fertilizer for acidic soils dust of 1–3 fields of electric filter of sintering furnaces of alumina production in form of fine powder with fraction less than 20 mcm is used.
EFFECT: technical result is reduced acidity of soil with improved structure.
