This useful model relates to the field of agriculture, in particular to the working organs of agricultural machines, and can be used both for seeding and for applying to the soil bulk and liquid fertilizers, as well as biological products.A vomer is known including a stand-holder with a spherical cutting blade rigidly fixed in its lower part, the holder-holder being mounted with an inclination and rotatable with respect to its longitudinal axis as a result of contact with the soil of the spherical cutting disc, in the cavity of the carrier-holder a tubular channel for feeding planting material and dry fertilizers with a diffuser fixed to its outlet, which is made in the form of a downwardly expanding plane, directed to the side opposite to the motion from the driver.A new feature of the coulter design is that a second tubular channel of smaller diameter is fixed in the cavity of the tubular channel for supplying liquid materials at the outlet of which the nozzle is fixed, directed towards the movement of the opener. In addition, the diffuser is connected to the tubular channel by an easily detachable and elastic connection, fan-shaped guide channels are formed on the upper surface of the diffuser, and walls are provided on the sides of the diffuser to prevent the loose materials from falling to the sides. 1 pic., 9 h. item f-ly.Настоящая полезная модель относится к области сельского хозяйства, в частности к рабочим органам сельскохозяйственных машин, и может быть использована как для высева семян, так и для внесения в почву сыпучих и жидких удобрений, а также биопрепаратов.Известен сошник, включающий стойку-держатель с жестко закрепленным в нижней ее части сферическим режущим диском, при этом стойка-держатель смонтирована с наклоном и с возможностью вращения относительно ее продольной оси в результате контакта с почвой сферического режущего диска, в полости стойки-держателя неподвижно установлен трубчатый канал для подачи посадочного материала и сухих удобрений с за
