Abstract
An apparatus is provided for dispensing a fertilizer in a pond. The apparatus includes a flotation structure which is generally surrounded by a porous material, such as a net sack. An opening is provided in the flotation structure through which fertilizer is dumped to deposit the fertilizer in the net sack wherein it is dissolved by water flowing through the net sack at the bottom of the flotation structure.
Claims14
An apparatus for dispersing fertilizer in a pond, comprising:
- a flotation structure, said flotation structure including a buoyant block and an opening defined through said block;
- a flexible porous material secured relative to and enclosing the bottom of said flotation structure;
- a collapsible reservoir disposed below said flotation structure, said reservoir defined by said flexible porous material so that the entire surface area of said reservoir is freely permeable by water;
- means for anchoring said flotation structure within the pond;
- and
- said flotation structure being of sufficient buoyancy to float on the surface of a body of water while at least the bottom of said buoyant block and said reservoir are immersed below the surface of the water.

An apparatus for dispersing fertilizer in a body of water, comprising:
- a buoyant block having sides and top and bottom surfaces, said block having an opening defined therethrough;
- a flexible porous net sack generally surrounding said buoyant block so as to encircle said bottom, sides, and top while providing access to said opening through said top of said buoyant block;
- a collapsible reservoir defined below substantially the entire said bottom surface of said buoyant block by said porous net sack;
- and
- said buoyant block being of sufficient size to float on the surface of the body of water with at least said bottom thereof being immersed in water, said opening providing means for dispersing fertilizer through said block, the fertilizer being held below said block within said reservoir by said porous net sack, said porous net sack being of a porosity so as to retain the fertilizer while allowing water to flow therethrough over the entire surface area of said reservoir to dissolve the fertilizer.
