Abstract
A dry chemical delivery tube and its surrounding nutrient applicator system are located in a narrow space in a soil working implement in an agricultural setting. Between an inlet end and an outlet end, the chemical delivery tube transitions from a circular cross section to an oval cross section. In one embodiment, the soil working implement includes soil opening/closing disks and liquid or gaseous delivery tubes that closely surround the chemical delivery tube.
