“…The experimental catchment is characterised by locally typical land use; 45% arable land, 37% forests (spruce production type predominantly), 13% meadows and pastures, 3.5% other surface (usually idled areas or wetlands), 1% orchards and gardens, and less than 1% of built up areas and water ponds. The upper and middle parts of the catchment slopes (especially flat hill tops) are usually ploughed except for the sites, mainly afforested, where the soils are too shallow or infertile (Doležal & Kvítek 2004). The study area consists of several subcatchments with vari- Table 2 for details.…”

“…The idle nitrate is washed out from freshly drained and ploughed soils in large amounts (Janeček 1981;Švihla 1992). So the tile drainage water, having ploughed districts as source areas and with high nitrate content, is now discharged directly into streams and frequently makes their water quality unacceptable even for a long time (Kvítek & Doležal 2003;Doležal & Kvítek 2004;Lexa et al 2006). A not negligible share on surface water nitrate concentration may represent point pollution sources as well as atmospheric deposition of S and N (Novotny & Olem 1994;Thornton & Dise 1998).…”

The ecological status of many surface waters in the Czech Republic is poor, mainly due to still relatively high discharges of N substances especially from agriculture. High nitrate values in the streams situated particulary in basins of drinking water reservoirs invoke the neccesity for the precise detection of diffuse pollution areas to enable the setting of the appropriate land management strategies or relevant measures. We introduce a simple method for estimating the changes of nitrate concentrations in surface waters regarding the land use modification. Stream and drainage water nitrate concentrations in prevailingly agricultural catchments of three different scales located in the Crystalline complex of the Czech massif were included in this study. Water quality samples were collected through the years 1992–2006 at monthly and bi-monthly intervals. For the catchment land use analysis, the satellite images LANDSAT 7 (CORINE Land Cover) and digitised cadastre maps of the land register were processed using ESRI ArcMap GIS; both sources corrected by field survey. We demonstrate on three different basin – scale studies a strong relation between the arable land ratio within a catchment and the coherent stream water nitrate concentration. The results acquired from all the evaluated catchments showed that every 10% decrease of ploughed land proportion in a catchment lowers the nitrate concentration C90 value (90% probability of non-exceedance) in average by 6.38 mg/l.

“…Related to C2, porosity of UC and C1 was increased by 4.5 and 3.0%, respectively, in relation to increasing SOM (by 7.0 and 6.6%, respectively), bringing about an increase of P n of UC by 31.3% and a decline of ρ d of UC and C1 by 9.5 and 6.0%, respectively. This process is particularly important and necessary in recharge areas of underground water resources, where there are usually soils with higher infiltration capacity, lighter with respect to granularity, a shallower soil profile, and lower production capacity (Doležal & Kvítek 2004). Relatively low growth of above ground phytomass may be expected and therefore a single annual cutting regime, combined with occasional non-cutting, is a suitable type of management without causing excessive risk of accumulation of standing dead material.…”

Changes of selected soil physical properties (porosity P, soil organic matter SOM, bulk density ρ d , particle density ρ z , characteristics of water retention capacity -maximum capillary water capacity θ CMC , and non-capillary porosity P n ) of permanent grassland (wet, non-fertilized, thistle meadows ass. Angelico-Cirsietum palustris, crystalline complex area, Czech Republic) in the top soil layer (3-10 cm) managed under three regimes (uncut UC; cut once a year C1; cut twice a year C2) were monitored for one undrained and two drained sites. There were no significant differences in selected soil physical properties among the test plots at the beginning of the study. As the intensity of utilisation decreased, the values of P, SOM, and P n increased and ρ d , ρ z and θ CMC decreased. Within 5-10 years of the beginning of the study, average values were: P at UC = 70, C1 = 69, C2 = 67%; SOM at UC = 10.7, C1 = 10.6, C2 = 10.0%; ρ d at UC = 0.76, C1 = 0.79, C2 = 0.84 g/cm 3 ; ρ z at UC = 2.53, C1 = 2.55, C2 = 2.56 g/cm 3 ; θ CMC at UC = 50, C1 = 53, C2 = 51%; P n at UC = 21, C1 and C2 = 16%. Moderate negative dependence of both ρ z and ρ d on SOM and of ρ d on P n and a moderate positive dependence of P on SOM was observed. θ CMC changes did not show links to other soil physical properties. The greatest looseness of the top soil layer, expressed by a decrease in ρ d , occurred with the UC regime in direct correlation with SOM, P n and P.
