FIELD: agriculture.SUBSTANCE: complex comprises at least one working platform and at least one service platform. Each platform comprises a bearing platform, a propeller with a drive, an angle of variation of platform motion direction, a power unit, a fuel unit and communications between them. The platforms include a control unit, a unit of information communication with other devices of the complex, a sensor of energy quantity, a sensor of fuel quantity, a unit of storage and exchange of process weights, a joint-exchange unit for exchange of energy, fuel, materials and replaceable modules with working elements with joined devices, a sensor to detect a position of the platform relative to the plantation, a sensor of process weights quantity, a sensor of replaceable modules condition. Working and service platforms differ to each other by the fact that the working platform additionally comprises at least one unit for fixation of replaceable modules, containing process working elements or auxiliary units, to the bearing platform - at least one replaceable module. The replaceable module comprises a process working element. The service platform additionally comprises a unit of storage and replacement of replaceable modules with a set of replaceable modules containing process working elements or auxiliary process units and a unit of lifting-lowering of the working platform. Additionally the complex may be equipped with a monitoring and control device and a device to monitor condition of a plantation. Each additional device includes a unit of control and a unit of communication. The device for monitoring of plantation condition additionally includes sensors of plantation condition. The method includes performance of process operations for handling of plants with a complex of devices described above.EFFECT: such structural design and technology will make it possible to automate the process of handling of a plantation of plants to the maximum with minimum expenditures of reso
