METHOD FOR OBTAINING SORPTION PREPARATION TO REDUCE ALLELOTOXICITY OF SOILS Russian patent published in 2021 - IPC B09C1/00 A01N31/08 A01N25/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in greenhouses. A method for obtaining a sorption preparation to reduce the allelotoxicity of the soil involves mixing an aqueous solution of bentonite and potassium or sodium humate in a mass ratio of 4:0.9 to 4:1.1, respectively, with continuous stirring for 5-6 hours to obtain a suspension. Next, the suspension is dried until a dry residue is obtained, followed by its grinding into a powder. The suspension of bentonite and humate has a concentration of 50-100 g/l and it is dried by holding at a temperature of 70-80°C until traces of visible moisture are removed. The grinding of the dry residue is carried out by an impact mill until particles of 5-200 mcm in size are obtained.

EFFECT: proposed method is aimed at obtaining a preparation that reduces the allelotoxicity of soils and, as a result, reduces the intake of allelotoxins into plants, accelerates the development of plants, increases their resistance to phytopathogens and pests and, as a result, increases yield.
