Authors(s) and Affiliation(s)



In experimental plots, annual losses of organic and inorganic matter in liquids and solids washed away are very low (e. g. Under beets: in 1975, kg/ha: KO: 1,1| CaO: 3,8, MgO: 0,6| NaO: 2,1| N: 0,4| SO: 2,1| PO: 0,4). During rather long periods of agressive rains, or during violent storms, losses are ten to twenty times more important as under ordinary rainfall. Expressed in fertilizer value, their amount approximates only a few hundred Belgian francs. Concerning eutrophication, contents of N and P measured in runoff surface waters exceed largely the maximum level accepted. (N: 7,1 mg/1| PO: 6,5 mg/1).
