A seend planter shoe adapted to lift displaced soil up and out of the planting furrow or furrows being formed as the shoe is drawn through agricultural soil, substantially without compressing the soil remaining in place and defining the furrow laterally, which shoe has a prow sloping upwardly and backwardly from a forward soil-penetrating point at and depending below the bottom of the shoe proper, which is substantially planar, and side walls that diverge backwardly and upwardly, from a prow piece to which they are rigidly joined, for from about one-half to about three-quarters the length of the shoe and continuing on longitudinally of the shoe substantially in parallel for the remainder of the length of the shoe. The side walls are preferably of steel plate faced outwardly over a substantial portion of their height by wear-resistant plastic plates and marginally of their bottom edges by strips of steel plate. The prow piece slopes backwardly at an angle of about forty-five to about fifty degrees, and preferably forty-seven degrees, to the planar bottom of the shoe. Preferably, a series of forwardly sloping, diagonal members are applied to the shoe exteriorly thereof along the bottom margins of its side walls to facilitate maintaining of proper depth as the shoe is drawn through the soil.
