ABSTRACT:
A soil opening implement comprising a frame (5) adapted to be moved across a ground surface to be opened, a soil opener (1) mounted on the frame for a repetitive cyclic movement to case the soil opener to penetrate the ground at a plurality of spaced positions to form a line of holes in the soil, and adjustment for varying the pitch of the holes, that is the spacing between adjacent holes in the direction of movement of the implement. The implement has the facility to deliver objects, such as seeds to fertilizer granules in the holes, either one object per hole or multiple objects per hole. The implement includes a hopper (11) for holding a supply of objects and for delivering the objects to the soil opener which is in the form of a substantially vertical hollow tube (11b) through which the objects are fed and delivered to the holes. The lower end (3) of the tube is angled and tapers to a point, the taper being formed by an angled cut on the trailing side of the opener relative to the direction of movement of the implement.
