FIELD: drying.SUBSTANCE: present invention refers to the system and method for drying grain in the grain bin, which contains humidity sensors and controllers. System controller for drying the grain is connected to the plurality of humidity sensors mounted in the grain bin at different locations and separately from each other. Controller determines the moisture level of the grain that is located next to each humidity sensor and compares the moisture level of the grain with the predetermined maximum moisture level. Controller is connected to the grain distributor, which is used in order to selectively distribute the grain entering the grain bin, and controls the distribution of incoming grain in order to create the shortened airflow path through the grain, which covers humidity sensors that determine moisture levels of grain, which are above the predetermined maximum moisture level. Controller is connected to the fan, which is connected to the grain bin and provides airflow through the grain in the grain bin. C
