A direct-connected, reversible, single-bottom plough (20), with subsoilers (22), which is associated with a reversible, surface ploughing device (23), as well as with a reversible collector member (37), that collects surface soil, and that is programmable so as to cause soil accumulated coming from surface ploughing and collected during the forward ride of the plough itself to drop at predetermined time intervals into the furrow so cut, so as to form in the furrow itself a series of basins of tubs of predetermined length and arranged in linear arrays in the sense of formation of said furrow, said basins being separated by transverse embankments or dividing walls of a given longitudinal size and being made up of the soil mass that has dropped out of said collecting member (37). The reversible sowing members (49), are also programmable so that they let seeds drop onto the transverse dividing wall just formed, the collector (37) and sowing members (49) operation being programmed by an electronic head having a pulse counting device provided with a storage and associated with a pulse generator which is acted upon by a wheel (27) in contact with the ground and put in motion by the ride of the plough itself. |
