MICRONIZED ALKALINE-EARTH METAL CARBONATE CONTAINING MATERIAL FOR REGULATION OF PH SOILS Russian patent published in 2018 - IPC C09K17/06 C09K109/00 C05D3/02 A01G25/02 

Abstract RU 2663124 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for controlling soil pH, as well as the use of at least one alkaline earth metal carbonate-containing material having a weighted average particle size d50≤50.0 mcm, to optimize or improve soil pH. Also described is the use of an irrigation or spray system to introduce an aqueous slurry comprising at least one alkaline earth metal carbonate containing material to optimize or improve the soil pH.

EFFECT: micronized carbonate containing alkaline earth metal carbonate is proposed to control soil pH.
