ABSTRACT:
A device intended for underground installation and microbiological decomposition of animal excrement has a tubular shaft having hinged closure means at its upper extremity and gripping means at its lower extremity which engage a large bucket. Mounted on the outer periphery of the shaft are an outwardly extending flange, spacer means to separate said flange vertically from the upper rim of said large bucket, and retainer means which function to position the shaft coaxially with said large bucket. A small bucket rests mouth upward on the inside bottom of said large bucket. The buckets confine a microbiologically active liquid. Excess quantities of said liquid are permitted to flow over the upper rim of said large bucket and enter an annular space surrounding said bucket from when the liquid dissipates into the earth. A tether means facilitates the lifting of the small bucket through said shaft. Sensor means are provided to conveniently determine the level of inert sediment accumulated within said small bucket.
