Abstract
A fertilizer dispensing device includes a tubular body which confines a chamber for receiving granular fertilizers having a first dimension, and which is adapted to be inserted into and buried by soil. The fertilizer dispensing device has a dispensing port formed through the tubular body. The dispensing port has a second dimension smaller than the first dimension so that the granular fertilizers could be carried through the port and into the soil when dissolved.

A fertilizer dispensing device comprising:
- a tubular body adapted to be inserted into and buried by soil, said tubular body having a bottom wall with a periphery, and a tubular wall extending from said periphery of said bottom wall in a longitudinal direction and cooperating with said bottom wall to confine a chamber, said tubular body further having an inner wall surface confronting said chamber, and an outer wall surface opposite to said inner wall surface and distal to said chamber;
- granular fertilizers, a smallest one of which has a first dimension;
- an upper tubular end extending from said tubular wall in the longitudinal direction to define an access opening to permit filling of said chamber with said granular fertilizers;
- a closure member disposed to close said access opening;
- and
- a dispensing port formed in said inner wall surface, extending through said outer wall surface, and having a second dimension smaller than the first dimension, whereby said granular fertilizers are retained in said chamber until said granular fertilizers are dissolved so as to be carried through said port and into the soil.
