Sealing of soils by liquid cattle manure
Authors: Culley, J. L. B. And P. A. Phillips
Description: Earth-lined in-ground pits have become a popular method of storing liquid live stock wastes due to their relatively low construction costs (Turnbull et al. 1977). To ensure that there is negligible leakage of manure nutrients, the current design recommendation is that these storages be clay-lined (Canada Plan Service 1979). For many farmers this presents no problem but some, situated on sandy or loam soils, might face considerable extra expense to truck in clay material for a liner. Could their own subsoil be as manure tight as clay? A laboratory-scale apparatus was set up to test the sealing rate of three soil types, sand, loam and clay, and to investigate the quality of leach ate from these soil columns. This research is a component of a long-term study to evaluate potential groundwater contamination from earth-lined manure storages under central Canadian conditions.
