"Instead of the usual cement floor found in commercial piggeries, the pigpens are excavated one meter deep then filled with a mixture of sawdust, clean soil and a little salt. To be more specific, for every 10 sacks of sawdust, 5 sacks of soil and one kilo of salt are mixed together. The mixture serves as the bedding that absorbs the manure as well as the urine of the animals."
I read this one, and just want to have a clarification, is that really one meter deep?
