Abstract
The introduction of mineral fertilizers has a negative impact on the agrobiocenosis. An increase the concentration of nitrate nitrogen in irrigation water in order to use it as a nitrogen fertilizer that does not have a negative impact on the environment seems relevant. The change in the content of nitrate nitrogen was determined in irrigation water, which was used as the flowing water of the city water supply (Moscow); pond water (Moscow region); potassium nitrate solution with a concentration of 50.9 mg/l. Three types of irrigation water were processed using a high-voltage installation. The experimental electrohydraulic installation consisted of a TVI-50/70 transformer with a rectifier unit; DC electric energy storage systems (high-voltage pulse capacitors); arresters designed to generate pulsed spark discharges with a short rise time; controls that allow changing technological modes during experiments; working units. During the research, an ITAN pH meter/ionometer was used according to the RD 52.24.367-2010 method. The technological mode of operation of the electro-hydraulic unit provides for the following characteristics: operating voltage 42 kV; capacitance of capacitors 0.05 μF; number of spark discharges n = 1 ... 5 thousand pieces; forming the gap between the ball arresters FP = 14 mm; working gap between working high-voltage electrodes 10 mm. Electrohydraulic treatment of water increases the concentration of nitrate nitrogen compounds in the running water of city water supply by 3.7 times (from 2.9 to 10.9 mg/l), in pond water - by 7 times (from 1.2 to 8.4 mg/l), in a solution of potassium nitrate - 1.3 times (from 50.9 to 68.4 mg/l). In water treated electrohydraulically, the content of nitrate nitrogen increases, which expands the possibilities for its use when watering plants.
