A method and apparatus for planting seeds. A V-shaped seed furrow having a predetermined depth is continuously formed while the soil adjacent each side of the furrow is uniformly firmed or compacted and a smooth surface formed. Seeds are continuously dispensed into the furrow. The walls of the furrow are then compacted about the seed as the furrow edges are collapsed over the seed to leave a comparatively non-compacted layer of soil above the seed. The planter is provided with a pair of furrow forming disks rotating about intersecting axes, a pair of gauge wheels rotatably supported rearwardly of the disk axes, each wheel being in close proximity to the outer surface of its respective disk, a seed dispensing means for delivering seed to the furrow, and a furrow closing device supported rearwardly of and in tracking relation to the gauge wheels.
