Abstract: Methods and apparatus for dispensing seed or other particulate matter in the air to apply the particulate matter generally evenly over a target area on the ground. The seeds are entrained in a viscous, elastic carrier fluid, which facilitates the movement thereof through hydraulic equipment and holds the seeds together in the air to preclude segregation or drifting as the particles drop to the target area. The seed and carrier fluid mixture is either premixed and stored in storage tanks in the apparatus or is mixed immediately prior to being dispensed in the air. One embodiment of the apparatus is utilized to broadcast seed over a relatively wide area and comprises a rotating spray head for dispensing the seed and carrier fluid mixture into the air. Another embodiment of the apparatus is used to apply rows of crop seed and comprises a dispensing head for providing a narrow stream of the seed and carrier fluid mixture into the air.
