“…The object of research is the root soil environment, where fruit crop systems, in particular wheat, ripen in trays with stable water supply. The analysis of literary sources [5][6][7][8][9][10][11][12][13][14][15] in the field of hydroponic green fodder, there is a tendency of uninterrupted water supply during the day. However, the problem of regulating the moisture content of the root part and the effect of the moisture content of the root system on stable growth, as well as the influence of various factors in ensuring the vitaminized proportion of the cultivated crop, have not been studied [16].…”

This article discusses the results of a study on the cultivation of hydroponic green feed in the laboratory, the main purpose of the study is to study the effect of humidity on the root system of the green mass, to increase the timing and dependence of the increment on temperature and humidity. The experience of using automation elements in order to develop recommendations for the implementation of automation systems and computerization of a hydroponic installation using a programmable microcontroller is analyzed. Taking into account the problems of growing green mass for use as feed for the agricultural sector, the issues of photosynthesis are considered, the results obtained and methods for measuring the concentration of free hydrogen ions in water (pH) are shown, for these purposes the water quality was monitored using Sensorex sensors, the issues of sprouting are described, as well as measuring the moisture content of the root part of the green mass and the devices used for this purpose. The article concludes that the results of the research are based on the use of various innovative solutions, this is a system of transition to digital agriculture, as a result of growing hydroponic green feeds using automation elements to control and manage the receipt of primary initial state information. This, in turn, will allow the agricultural sector to be fully automated, free up useful areas of land, increase yields and reduce production costs.

The aim of the work is to determine the permissible load factors of step-down transformers when powering various types of greenhouse irradiators. All examined irradiators have nonlinear volt-ampere characteristic and generate upper current harmonics. The object of research are greenhouse illuminators with high pressure sodium lamps, induction and light-emitting diodes greenhouse illuminators (LED) with active and passive power factor. The permissible load factors of transformers are calculated using obtained data: for high-pressure sodium lamp light is 0.95 max; for LED lamps with active power factor corrector – 0.76 max; for LED lamps with passive power factor correction – 0.59 max; for electrodeless lamp light – 0.98 max. To reduce current harmonics in systems with LED lamps and to increase the load factor of transformers, it is necessary to apply special devices – active or passive harmonic filters. For greenhouse irradiators with sodium lamps and induction irradiators, the use of harmonic filters is not required.
