Abstract
Abstract A sprinkler feeder having a bowl body for holding agricultural fertilizing chemicals in solid granule and pellet form, a lid for the body for maintaining the fertilizer therein, the lid provided with perforations whereby water directed into the lid may flow through said perforations for contact with the fertilizing chemical to dissolve the same. The body is provided with a perforated base and means for supporting same above a spray head or for attachment to a water nozzle in such a manner that water emitted from the nozzle or by the spray head has a portion thereof directed into the cup. As the fertilizer dissolves it flows through the perforations in the base of the body. A central overflow or discharge tube extends from the interior of the cup through the body for discharge into the water spray from head or nozzle thus distributing fertilizer over an area covered by the water spray.
