IRRIGATION SYSTEM OF NUTRIENT SOLUTION Russian patent published in 2012 - IPC A01G25/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The proposed system comprises one line of water supply, which is connected with the mixing tank through the sand-gravel filter and a water supply pipeline, and a drip irrigation network, the control unit connected to the irrigation pump, a flow meter, valves of dosing the matrix solutions and acids, water valve, irrigation valves and a sensor of level of liquid, conductivity and pH. On the line of water supply the water filter and the water valve is mounted. The irrigation system is connected to the mixing tank through the irrigation pipeline, on which the irrigation pump, a filter for irrigation solution and irrigation valves are consistently mounted. The irrigation pipeline in the area between the flow meter and the irrigation pump is connected via ejection pipe with at least one ejection pump to supply the matrix solution, and with one ejection pump to supply acid. The inputs of the ejection pumps to supply the matrix solution and acid through the valves of dosing are connected respectively with tanks for matrix solution and acid, and the outputs - with a mixing tank. On the ejection pipe at least one sensor of electrical resistance is mounted, and at the input to the ejection pumps the ejection pipe is connected with the mixing tank through the bypass pipeline on which at least one pH sensor is mounted. The sensors of level of liquid are mounted in the mixing tank and tanks for matrix solutions and acid.

EFFECT: invention improves the accuracy of dosing of nutrients, provides the ability to control the parameters of irrigation solution.
