Disclosed is a novel coulter closing wheel assembly and a method of planting crops. Also disclosed is a mid row banding pneumatic coulter drill used to support the unique coulter assemblies. The seed coulters and fertilizer coulters are positioned such that in the direction of the travel one fertilizer coulter is positioned between two seeding coulters. The seeding coulters are always followed by a furrow closing wheel which in effect scrubs the ground and pushes soil back into the furrow. The seeding coulters are also followed directly by a press wheel or packer wheel. The fertilizer coulters may or may not employ a furrow closing wheel, depending on the type of fertilizer which is being placed in the soil and to a lesser degree depending on the type of soil. In the event of granular or liquid nitrogen fertilizers the closer wheel is generally not necessary. However, when a gaseous fertilizer such as anhydrous ammonia is applied to the soil, the furrow closing wheel 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.
