METHOD OF OBTAINING CONCENTRATE OF NUTRIENT COMPOSITION FOR GROWING AGRICULTURAL CROPS IN HYDROPONIC SYSTEMS Russian patent published in 2023 - IPC C05D9/02 A01G31/00 

FIELD: agriculture.

SUBSTANCE: invention relates to crop production without soil, and can be used in hydroponic and greenhouse methods of growing agricultural plants. A method of obtaining a concentrate of nutritional composition for growing crops in hydroponic systems involves dissolving of the following components, in the elements equivalent, wt.%: 4.4% of nitrogen, 4% of potassium, 0.18% of calcium, 0.09% of magnesium, 0.2% of sulfur, 6.13% of phosphorus, 0.005% of iron, 0.28% of boron, 0.0005% of copper, 0.001% of zinc, 0.002% of manganese, 0.057% of molybdenum, the rest is water, at pH of 6.5–8 and a temperature of 20–25°C.

EFFECT: invention makes it possible to increase the mass of agricultural plants, plant productivity and the stability of the nutrient solution at pH above 7.
