FIELD: agriculture.

SUBSTANCE: method consists in performing the process operations of agricultural technology in the field with a working unit mix, wherein the pre-sowing operations are performed without processing flaws. The working unit mix is determined from the alternative unit mix, from the basic agricultural technology unit mix according to the cost minimisation criterion. The composition, motion track, and control parameters of the working bodies determining the deactivation of sections in the current position of the section in the processed areas of the field, the seeding and plant protection units, are determined according to the cost minimisation criterion, additionally including the yield loss damage determined from the area of processing flaws with account to the inclusion of circular bypassing of obstacle objects in the motion track. The modelled area of the processing flaws is determined from the sum of the number of markers of a certain type on the two-coordinate plane of the model of the field: S_is=n_is·k_sp, S_js=n_js·k_so, wherein S_is, S_js are the areas of processing flaws, n_i, n_j are the number of markers, is, js are the type of processing flaw, k_sp, k_so are the scale of the area of the seeding and spraying markers, m². The motion track is modelled, and the control parameters of the working bodies of the unit are determined in alternative variants of motion differing in the inclusion of circular bypassing of obstacle objects and the entry point into the field in the motion track. The entry point into the field in the motion track is determined with the minimum value of the area of processing flaws. The inclusion of circular bypassing of obstacle objects is determined by solving the cost minimisation criterion for the alternative variants. The seeding or plant protection operations are performed in accordance with the determined unit mix, motion track, and control parameters of the working bodies.

EFFECT: reduction in the loss of the gross product, i.e. grain, related to processing flaws.
