Abstract
Abstract An apparatus and method are described which facilitates the filling of mushroom beds with compost and the covering of a composted and spawned mushroom bed with casing soil. A hopper means adapted to be affixed temporarily to one end of a mushroom bed is provided with means for delivering compost and casing soil from the hopper onto a flexible sheet which in turn is adapted to be pulled lengthwise of the mushroom bed. As the sheet is pulled away from the hopper a retroverted portion of the sheet continuously deposits the compost into the bed or the casing soil on the top of the compost uniformly covering the bed. The sheet is pulled by a winch operated cable, and the winch and hopper are mounted outboard of the mushroom bed so as to be suitable for use with a frame containing a plurality of vertically arranged beds.
