A seeding device principally for no-tillage seeding conditions comprises a drag arm carrying two disk blades and transmitting the necessary forces thereto to cut through crop residues at the ground surface and to open a furrow for seed placement in the soil. The smaller disk is oriented vertically, whereas the larger disk extends at a compound angle from a lower front contact point between the two disks which thus define a V-shaped opener. The larger disk is angled relative to both the direction of travel and to a vertical axis to cut through residues and the soil and to displace a volume of soil for forming a trench. The smaller disk retains soil on a side of the furrow to allow a tube to deliver seeds therein. The smaller blade can also cut residues at the point of contact between the two disks to avoid trash buildup thereat. A depth control wheel which follows the ground surface in order to maintain the disk blades at a constant depth during furrow opening can be adjusted to obtain various seed depths in the soil. At the rear end of the seeding device, a press wheel closes the furrow by replacing the disturbed soil into it and firms the soil around the seeds. The press wheel can be spring biased towards the ground and the spring force adjusted so that the press wheel exerts the appropriate pressure on the soil surrounding the seeds.
