Range of horizontal transport and residence time of nitrate in a mature karst vadose zone

Popis výsledku v původním jazyce

Nitrate concentrations in drips in Amaterska, Spolecnak, and Holstejnska caves situated below a 25 to 120 m thick vadose zone in the Moravian Karst, Central Europe were studied during several periods from 1992. Each cave runs below a land-use boundary between fertilized lands and forest, which enabled study of the range of horizontal components of nitrate transport in the vadose zone. Parts of the fertilized land were turned into grassland in 1998 and 2003, and the cave drips were sampled both prior andafter the changes in land use. The mean residence time of nitrate is <10 years in the 25-30 m thick vadose zone, but >16 years in the 105-120 m thick vadose zone. The maximum range of horizontal nitrate transport (H-max) is 18 m in the 105-120 m thick vadose zone. H-max was normalized by the vadose zone's thickness (T). In the Moravian Karst the H-max/T ratio is <0.2. A low H-max/T between 0.1 and 0.6 was observed in the Czech and Slovenian karst areas, unaffected by glaciations, and wi
