FIELD: agriculture.
SUBSTANCE: device for introduction of liquid fertilisers with irrigation water in drip irrigation systems comprises a water source, a sump, a pump station, a filter with gauges, an irrigation network in the shape of a main pipeline with distribution and irrigation pipelines with droppers. To the distribution pipeline there is connected a feed pipeline with liquid fertilisers, the lower section of which is made with a transition two-phase nozzle with a spiral loop, the opening of which is made in the outer wall in the shape of a longitudinal slot. Branch encloses the spiral on the side of the slot and is connected with a diffuser, which, by means of a drain pipeline, is connected to solid fraction holding tank, after which the end of the outlet spiral loop is connected with the help of a pipe with a chamber and active nozzle.
EFFECT: high reliability.
