Abstract
Currently, in the process of global climate change, there is a shortage of specific resources in every corner of the world, and the weather is changing dramatically. In this article, for the first time, in the process of using the subsoil irrigation system, in the cultivation of fine-fiber cotton, it is possible to obtain certain analytical conclusions by creating a mathematical model for determining the distribution width of moisture and analyzing its specific indicators. Through the mathematical model, it is possible to determine the distribution width of water moving based on the gravitational force of water and the moisture level in the soil based on the saturation state, depending on the type of soil.
