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 article presents the results of a study of the effect of silica-containing fillers on the structure formation of a composite cement binder. Obtaining results allows the use of active fillers in cement sources, which allows to reduce the proportion of binder without loss of density, which is the result of using the resource of energy-saving research technologies in the field of building material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
