METHOD OF OBTAINING NUTRIENT SOLUTION FOR IRRIGATION AND/OR FEEDING OF CULTIVATED PLANTS Russian patent published in 2010 - IPC C09K17/00 

FIELD: agriculture.

SUBSTANCE: CO₃ from compressed air is dissolved in water in the saturator to form chemical bonds. The resulting volume of nutrient solution is supplied from the saturator to watering through irrigation-fertilising watering system. Selection of the purified carbon dioxide is carried out from atmospheric air by pumping it into the saturator using an air compressor. The volume of saturator is preliminary filled with water with the possibility of forming an air cavity. Air pumping to the saturator is carried out up to inception in air cavity of pressure above atmospheric pressure. Then a vent of the air to the atmosphere is carried out when pumping through the cavity of the compressed air supplied by the compressor. Due to it the previously created air pressure is maintained in air cavity until inception of nutrient solution with the desired concentration of dissolved carbon dioxide. Air flow supply into the saturator is carried out through the bottom of the saturator under pressure, ensuring its pumping into the air cavity of the saturator through the volume of waterspout.

EFFECT: simplification of irrigation and nutrition of plant technology, and increased yield of growing products.
