Abstract

A coulter closing wheel assembly, a method of planting, and a mid row banding pneumatic coulter drill assembly support vehicle. One fertilizer coulter is positioned between two seeding coulters. The seeding coulters are followed by a furrow closing disc which scrubs the ground and pushes soil back into the furrow. The seeding coulters are also followed directly by a packer wheel. The fertilizer coulters may or may not employ a furrow closing disc, depending on the type of fertilizer and the type of soil. In the event of granular or liquid nitrogen fertilizers the closing disc is generally not necessary. However, when a gaseous fertilizer such as anhydrous ammonia is applied to the soil, the furrow closing disc is necessary in order to prevent the escape of the anhydrous ammonia into the atmosphere. The coulters are firmly attached to horizontal frame members of the drill and placed at an angle of a few degrees off the direction of travel. The injection of fertilizer directly between a pair of seed rows ensures a steady supply of nitrogen or other fertilizers throughout the growing period. In addition, since the fertilizer is placed a fair distance from each of the seed rows, it will not scorch or burn the roots of the growing crop.
