    Abstract: A hydro-pneumatic method and apparatus for singulation and delivery of uncoated capsules that consist of gel-encapsulated propagules. The capsules are flowed in water to a metering zone, where a metering disc picks up capsules one at a time successively by vacuum from the metering zone while spacing the capsules at regular intervals. The disc carries the capsules from the water, and then positively blows them from the vacuum at the regularly spaced intervals.
