E.  aDesign concepts and construction costs of eight different manure storages.  c1977  aUsing the unit-quantity method, construction costs were estimated for four liquid manure and four semisolid or soil manure storage designs developed by the Canada Plan Service. For comparison, costs were plotted against storage volumes log-log paper, for two or three limiting sizes of each design. Retangular roofed storages were the most expensive,ranging from 0.95 to 0.75 $/ft3. Earth-hanked storages were least expensive where suitable soil (clay) was available on-site or nearby. Or concrete liquid manure tanks, the aboveground silo was least expensive.The curbed storage slab for stacked solid manure was also relatively cheap, but suitable only for dry or bedded manure. Surface/volume ratios were calculated for the unroofed storages as an aid to selecting...  astorage  aAdubo  aArmazenamento  aSilo  aConstrucao  aConstruction  aManure1 aPHILLIPS, P. A.1 aHORE, F.
