FIELD: agriculture.
SUBSTANCE: agricultural machine includes a frame and at least one opener for fertiliser application, installed on the frame and is designed for opening furrows in the soil. Each opener for fertiliser application includes the disk located at an angle to the working direction, a runner located behind the opener disc towards the working direction, and at least one tube for fertilisation. The tube is located behind the runner towards the working direction. The runner has a groove in its rear edge. The groove at least partially covers at least one tube for fertilisation. In another embodiment the opener has a groove in its rear edge towards the working direction. The protrusion is made with an ability of at least partial enclosing of at least one tube for fertiliser.
EFFECT: proposed design concept enables to improve the quality of fertiliser application, as well as reduce operating costs during the transition from one type of fertiliser to another.
