Notas: 	Título em inglês: Leaching of plant nutrients from vineyard soils.	
Conteúdo: 	Leaching of plant nutrient particulary of nitrate from vineyard, arable, and forest soils of the middle-mosel have been investigated over a two-year period. Nitrate concentration in the leachate of vineyards amounted to an average of 326 mg NO3/l and was  about 10 to 20 times higher than the nitrate concentration in the leachate of arable and forestsoils. According to the hydro-dynamic model assumptions on groundwater flow in the slates of the rhenish massif, the data obtained for the groundwater recharge (158-180 mm/year as gained in spring) and leaching of nitrate (144 kg N/HA/year) must be considered as minimum values. Hydrodinamic model assumption suggest nitrate leaching rate of about 200 kgN/ha. Main raisons for the high leaching of nutrients are heavyfertilizer application and high mineralization rates in the vineyard soils favoured by relatively high soil temperature and a high soil permeability.
