    • An agricultural system (10) for applying a granular fertilizer to soil in a field is disclosed. The agricultural system (10) comprising: a metering device (36) including a cavity (92) adapted to hold the granular fertilizer, wherein the metering device (36) provides gravity fed fertilizer from a metering device output (48) connected to the cavity (92); a fertilizer hose assembly (42) defining a fertilizer hose channel between a fertilizer hose assembly input and a fertilizer hose assembly output (54), the fertilizer hose assembly input operatively connected to the metering device output (48) to receive the gravity fed fertilizer from the metering device (36), wherein the gravity fed fertilizer flows through the fertilizer hose channel; a sensor device (56) disposed along the fertilizer hose assembly (42) between the fertilizer hose assembly input and the fertilizer hose assembly output (54); a blower (70) adapted to deliver an airflow through a blower hose (76), wherein the blower hose (76) is operatively connected to the fertilizer hose assembly (42) between the fertilizer hose assembly input and the sensor device (56), wherein the airflow is directed into the flowing gravity fed fertilizer to accelerate the gravity fed fertilizer through the sensor device (56) and toward the fertilizer hose assembly output (54) and an opener (18) adapted to provide a trench in the soil and located at the fertilizer hose assembly output (54), wherein the trench receives the accelerated gravity fed fertilizer provided by the fertilizer hose assembly output (54).
