Abstract. Depending on the utilization factor of the shift time, a sequence is given for optimizing the operational parameters and operating modes of the MTA for applying fertilizers. At the same time, the various operating conditions of its operation are taken into account and options for combinations of operational parameters and operation modes of the MTA are drawn up. As a result of the optimization search, their values are determined according to the criterion of minimizing the reduced costs. On the basis of which the economic efficiency of MTA is compared.
