CONCENTRATED AQUEOUS COMPOSITION OF MICROFIBRILLATED CELLULOSE CONTAINING PLANT NUTRITION SALTS Russian patent published in 2024 - IPC C05F11/00 C05F7/02 

FIELD: plant growing.

SUBSTANCE: group of inventions relates to the field of plant growing, in particular to hydroponics and fertigation. Concentrated aqueous suspension for plant nutrition, in wt./wt.%, includes: from 60% to 90% of water, from 1% to 40% of microfibrillated cellulose (MFC), from 1% to 55% of calcium nitrate, from 0.01% to 0.5% of magnesium salt of EDTA, from 0.01% to 0.7% of manganese salt of EDTA, from 0.01% to 0.7% of zinc salt of EDTA, from 0.01% to 0.9% of iron salt of EDTA, from 0.01% to 0.1% of EDTA copper salt, from 0.001% to 0.01% of sodium molybdate (dihydrate), from 0.0001 % to 0.001 % of cobalt EDTA salt, from 0.01 % to 0.4% of boric acid, from 1% to 12% of potassium nitrate, from 0.5% to 25% of potassium monophosphate, from 0.5% to 42% of magnesium sulphate, from 0.1% to 11% of potassium sulphate. Microfibrillated cellulose (MFC) prevents sedimentation of salts in the range of pH from 1 to 13, ensuring availability of salts for plant growth. Method of producing solid fertilizer involves a step for dehydrating an aqueous concentrated suspension to obtain a solid consistency product. Method of producing solid fertilizer involves a step of pouring an aqueous concentrated suspension into a mould and dehydrating it to obtain a moulded solid consistency product. Solid fertilizer obtained by the method contains an aqueous concentrated suspension which is dehydrated.

EFFECT: inventions provide simplification of obtaining a balanced composition of fertilizers.
