The invention relates to a farm implement for adding organic fertiliser or compost subterraneously to cultivated land. The implement is characterised in that it comprises a chassis that defines three coupling points between the implement and the tractor or towing vehicle and is adapted for the joint mounting of at least one or more lower subsoilers separated from one another and aligned transversely and one or more hoppers for metering organic fertiliser or compost, said hoppers being secured to the upper part of the chassis. According to the invention, the hoppers comprise mechanisms for metering the organic fertiliser in order to discharge same through a lower outlet to which a pipe is connected that is secured to a guide structure for discharging and metering the organic fertiliser. In addition, each subsoiler is placed in front of, and below each hopper for metering the organic fertiliser or compost in order to open up the soil and generate a furrow or groove in which the organic fertiliser is deposited subterraneously. The chassis also comprises a lateral arrangement on which side wheels are mounted independent of the tractor or towing vehicle.La invención se refiere a un implemento agrícola para incorporar en forma subterránea abono orgánico o composta en terrenos de cultivo, caracterizado por comprender un chasis que define tres puntos de acoplamiento del implemento con el tractor o el vehículo de tiro y está adaptado para montar asociadamente al menos uno o una pluralidad de subsoladores inferiores separados entre sí y alineados transversalmente y al menos una o una pluralidad de tolvas de dosificación de ábono orgánico o composta fijas en la parte alta del chasis, en donde dichas tolvas comprenden mecanismos de dosificación del fertilizante orgánico para descargarlo por una salida inferior donde se conecta un conducto fijo en una estructura guía de descarga y dosificación del fertilizante orgánico y en donde cada subsolador se dispone delante y por debajo d
