A blade, e.g. a fertilizing blade, connectible via a spring (4) to a sowing and/or fertilizing device comprises an elongate member (1) and a blade body (2) positioned behind the blade member (1). The elongate blade member (1) extends in the direction of travel and has a rectangular cross-section. The blade body (2) has a width at its front edge no greater than the width of the blade member (1) and preferably has a width substantially the same as that of the blade member. <IMAGE> |
