When constructing experimental mathematical models of the processes under study, it is proposed to use mathematical modeling based on the physical principle of the balance of cause-and-effect interactions in a closed physical system. The essence of this principle is revealed and examples of its application are given in the derivation of the "Darcy's law", the formula of S.F. Averyanov, who connects the moisture conductivity of the soil with the filtration coefficient, when substantiating the structure of the mathematical model of agricultural crops yield
