METHOD FOR LEAF DIAGNOSTICS OF PLANTS NEED FOR MINERAL NUTRIENTS Russian patent published in 2024 - IPC A01G7/00 B01D15/00 G01J3/00 

FIELD: agriculture.

SUBSTANCE: method for diagnosing the need of plants for mineral nutrients by the value of photochemical activity of chloroplasts is characterized by the fact that it includes illumination on a photometer of solutions with a mixture of salts of the analysed nutrients together with a solution of a suspension of chloroplasts of plants, Tillmans paints and sodium chloride, which are prepared in a single light-protective container before illumination on a photometer, wherein solutions of mixtures of salts of the analysed power elements are simultaneously taken from the test tubes of the set of consumables by a multichannel pipette and placed into separated quartz test tubes, then a solution of a suspension of chloroplasts of plants is simultaneously taken from a single light-protective container by a multichannel pipette, Tillmans dyes and sodium chloride and added to separated quartz test tubes, solutions in quartz test tubes are illuminated simultaneously on a multichannel photometer.

EFFECT: invention makes it possible to speed up diagnostics and minimize error in obtaining diagnostic data.
