The U.K and most of the EU, pumps almost all its sewage sludge (solids from sewage farms) onto farmland. Have you never seen tankers parked in small country lanes attached to tractor driven pumps and miles of pipe?
Sorry, I expressed myself poorly. I meant raw human excrement...taken straight from the night bucket and tipped directly on the fields. I knew about sewage sludge, but that`s treated in several different ways first.
