An agricultural implement is directed to delivering multiple fluids to the soil of an agricultural field. The implement includes a frame for carrying a soil cutting device and a closing device. The cutting device forms a furrow in the soil and the closing device, which trails the cutting device, closes the furrow. A fluid delivery tine is mounted on the frame and extends downwardly into the furrow between the cutting device and the closing device. The tine has a pair of coaxial tubes, including an outer tube and an inner tube, wherein the coaxial tubes form an outer passageway between the outer tube and the inner tube for delivering a first fluid toward the furrow. The inner tube has an internal passageway for delivering a second fluid toward the furrow. |
