Processes of monitoring and control the industrial greenhouses microclimate play a
decisive role in growing crops under protected cultivation. Providing optimal climatic conditions
in the production process of greenhouse agricultural products requires solving the scientific and
applied problem of developing and researching a mathematical model for monitoring carbon
dioxide concentration in industrial greenhouses. The proposed model takes into account the
processes of diffusion and absorption of carbon dioxide, the geometric parameters of
greenhouses, as well as the types and vegetation periods of crops grown under protected
cultivation. Time characteristics of the carbon dioxide dynamics process under greenhouse
conditions are estimated. Quantitative estimates of the diffusion transfer duration and carbon
dioxide absorption are made for indeterminate varieties of tomatoes during planting and fruiting
periods. Recommendations are given on the development of an adaptive methodology for the
functioning and structural and algorithmic organization of computerized monitoring and
management system for carbon dioxide top-dressing modes for greenhouse crops. The necessity
of improving the proposed mathematical model and confirming the adequacy of its
implementation efficiency on yield indicators of greenhouse crops is substantiated.
