Abstract

Abstract The article discusses the issue of increasing the efficiency of plant nutrition by treating liquid organic and mineral fertilizers with an electro-hydraulic effect. The amount of nitrates in water is reduced to 1.1 mg/l due to electro-hydraulic treatment. This creates the possibility of feeding plants and at the same time eliminating E. coli bacteria in liquid fertilizers from 2.23 mg/l. up to 102.7%, i.e. 82.55% compared to the control in exchange for its neutralization, which can prevent it from passing through the plant into the human and animal body, resulting in human health being maintained. As a result of the research, a process for electrohydraulic processing of liquid fertilizers was established, where the following processing modes and parameters were established to ensure the degree of grinding of solid particles in the liquid, processing voltage: U = 24 kV, capacitor capacity: C = 0.8 μF., number of pulses: n=175 pulses, which turned out to be sufficient. Due to electro-hydraulic processing the rate of fertilizer uptake by plants has been improved over existing technology by optimizing the breakdown of coarse fertilizers into liquid solution through electro-hydraulic treatment of liquid fertilizer solutions. As a result, it was possible to increase the yield to 33 g for tomatoes and 37 g for cucumbers per 1 hectare owned by the farm using the method of electro-hydraulic treatment of liquid fertilizers.
