Glossar:Cover of storage facilities for manure/de

roofs of concrete, wood or corrugated metal, usually supported on poles at the periphery of the store
plastic, wood or concrete covers, usually supported by the walls of the store
tents, designed to float on slurry, normally of reinforced plastic sheet attached to the rim of an above ground circular store and supported by a central pole
floating sheets, normally made of reinforced plastic sheet, sometimes incorporating floats of e.g. polystyrene used for both above ground circular store and lagoons. The sheet may either be attached to the rim of the store and large enough to account for the rise and fall in the level of slurry in the store or float freely on the surface, sometimes supported by floats or sliding up and down vertical poles at the inner wall of an above ground store
natural surface crusts which forms when a quite solid upper layer of material is developed due to no stirring
semi-natural surface crusts, obtained by adding material such as straw, clay, or other material to the storage
