Dunno what it was full of, but plants seemed to thrive on its application - (:-) OK if you don't grow vegetables. Well it used to be collected from Hong Kong and taken to the New Territories as Night Soil, used to improve the fertility of the soil for veg growing, the produce was then sold in Hong Kong and so the cycle was started again. They still use human sewage sludge in the UK for agricultural fertiliser - after it's been through the usual treatment processes. They call it "biosolids" and try not to use the word sewage too much in descriptions these days to make it sound more up to the minute and respectable as a fertiliser. Field grown crops we all eat have often been grown with the useful aid of human poop, whether we know it or not. Got to use the stuff somewhere or we'd all be up to our knees in it by now! -- Sue |
