FIELD: agriculture, in particular, irrigation equipment. SUBSTANCE: sprinkling machine has rotary bend equipped with shutter mounted on machine pipeline. Additional pipeline is connected to machine pipeline upstream of shutter via hydraulically controlled valve with hydraulic drives of self-propelled carts. Hydraulic drive of hydraulically controlled valve is connected to control pipe of outer protective system. Drain lines of hydraulic drives are equipped with working fluid sprinklers for feeding ground parts of plants, treating plants with pesticides and growth promoters. Working fluid is delivered from dosing device made in the form of hydraulic drive divided by piston into upper and lower cavities. Lower cavity is connected to additional pipeline via return valve and dosing faucet. Upper cavity is directly connected to additional pipeline.
