METHOD OF SOIL MOISTENING IN MOUNTAINOUS AND PIEDMOUNT ZONES WITH LANDPLOTS IRRIGATED WITH CATTLE BREEDING WASTEWATERS ALONG FURROWS AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC A01G25/00 

FIELD: agriculture.

SUBSTANCE: system includes sections with compacted dead-end irrigation funnels for irrigation with cattle breeding wastewaters and beds. The system is equipped with an irrigation source, a self-forcing pipeline, a pump and an automated control system. The irrigation source is connected to the self-forcing pipeline inlet. The self-forcing pipeline is laid along the maximum landscape slope. The self-forcing pipeline inlet is connected to the cattle breeding wastewaters delivery pipeline via the pump. Irrigation pipelines with monohydrants for delivery of water into the group of compacted dead-end irrigation funnels are connected to the self-forcing pipeline via membrane drive valves. Some of the compacted dead-end irrigation funnels are arranged at an angle to the landscape horizontal lines while other - parallel to the horizontal lines. The automated control system is equipped with a capacitive integral humidity sensor and a waster level sensor at the irrigation funnels end. The humidity sensor is represented by a porous tube. Inside the porous tube there are two electrodes arranged represented by plates constituting a capacitor. Along the beds middle a non-irrigation funnel is arranged. The non-irrigation funnel is lined with a strip of perforated polyethylene film. On top of the perforated polyethylene film a gravel crest is strewn. The irrigation funnels are screened from the lower part of the active soil layer with a strip of polyethylene film. The method involves discrete technology irrigation with variable irrigation streams flow and distribution of irrigation norm issue.

EFFECT: such design and technology insures prevention of non-process loss of irrigation water related to in-depth filtration, discharge and evaporation, prevent erosion and soil structure destruction due to irrigation, improve uniformity of irrigation norm issue along the irrigation funnels length, thermal and water-and-air conditions within the soil stratum adjacent to the surface, increase irrigation funnels length, reduce irrigation water expenditures and activate biological processes in the soil.
