Dung Installations as Dangerous Point Sources Burdening the Groundwater of Ljubljansko Polje

Abstract

On Ljubljansko polje, we registered 155 farmers with barns, mostly with the separate collec-tion of dung with litter and dung-water. We surveyed 307 dung installations, of which 151 were dunghills and 156 dung-pits. The traditional method of storing cattle manure in dunghills on top of dung-pits dom-inates. Some 231 of the dung installations are properly arranged, and almost two thirds have a suitable capacity.
