    Abstract: A soil opener comprises a tip attached to or integral with a body. The tip includes furrowing prow for cutting a furrow in the soil surface, a protrusion on the underside of the tip for cutting a trench within the furrow, and a seed distributor for depositing seeds within the furrow in laterally displaced seed rows. The body includes a seed passage for directing a seed stream to the seed distributor, a primary fertilizer passage for depositing a primary fertilizer stream, and a secondary fertilizer passage for depositing a secondary fertilizer. As the soil opener is moved across the soil surface, the body opener deposits primary fertilizer in the vicinity of the seed rows, and secondary fertilizer between the seed rows in a trench slightly below the surface of the seeds.
