There is little information on DOC fluxes and the relationship between DOC concentration and water flux in agricultural soils. The DOC fluxes and concentrations were measured during 2.5 yr using 30 automatic equilibrium tension plate lysimeters (AETPLs) at 0.4 m and 30 AETPLs at 1.20-m depth in a bare luvisol, previously used as an arable soil. Average annual DOC fluxes of the 30 AETPLS were 4.9 g C m(-2) y(-1) at 0.4 m and 2.4 g C m(-2) y(-1) at 1.2 m depth. The average leachate DOC concentrations were 17 mg C L(-1) (0.4 m) and 9 mg C L(-1) (1.2 m). The DOC concentrations were unrelated to soil moisture content or average temperature and rarely dropped below 9 mg C L(-1) (0.4 m) and 5 mg C L(-1) (1.2 m). The variability in cumulative DOC fluxes among the plates was positively related to leachate volume and not to average DOC concentrations at both depths. This suggests that water fluxes are the main determinants of spatial variability in DOC fluxes. However, the largest DOC concentrations were inversely proportional to the mean water velocity between succeeding sampling periods, suggesting that the maximal net DOC mobilization rate in the topsoil is limited. Elevated DOC concentrations, up to 90 mg C L(-1), were only observed at low water velocities, reducing the risks of DOC-facilitated transport of contaminants to groundwater. The study emphasizes that water flux and velocity are important parameters for DOC fluxes and concentrations. 000057155 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000057155 588__ $$aDataset connected to Web of Science, Pubmed 000057155 650_2 $$2MeSH$$aBromides 000057155 650_2 $$2MeSH$$aCarbon: analysis 000057155 650_2 $$2MeSH$$aSoil: analysis 000057155 650_2 $$2MeSH$$aWater Movements 000057155 650_7 $$00$$2NLM Chemicals$$aBromides 000057155 650_7 $$00$$2NLM Chemicals$$aSoil 000057155 650_7 $$07440-44-0$$2NLM Chemicals$$aCarbon 000057155 650_7 $$2WoSType$$aJ 000057155 7001_ $$0P:(DE-Juel1)129548$$aVanderborght, J.$$b1$$uFZJ 000057155 7001_ $$0P:(DE-Juel1)VDB724$$aKasteel, R.$$b2$$uFZJ 000057155 7001_ $$0P:(DE-Juel1)VDB2346$$aPütz, T.$$b3$$uFZJ 000057155 7001_ $$0P:(DE-HGF)0$$aMerckx, R.$$b4 000057155 7001_ $$0P:(DE-HGF)0$$aFeyen, J.$$b5 000057155 7001_ $$0P:(DE-HGF)0$$aSmolders, E.$$b6 000057155 773__ $$0PERI:(DE-600)2050469-X$$a10.2134/jeq2006.0368$$gVol. 36, p. 597 - 606$$p597 - 606$$q36<597 - 606$$tJournal of environmental quality$$v36$$x0047-2425$$y2007 000057155 8567_ $$uhttp://dx.doi.org/10.2134/jeq2006.0368 000057155 909CO $$ooai:juser.fz-juelich.de:57155$$pVDB 000057155 9131_ $$0G:(DE-Juel1)FUEK407$$bErde und Umwelt$$kP24$$lTerrestrische Umwelt$$vTerrestrische Umwelt$$x0 000057155 9141_ $$y2007 000057155 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000057155 9201_ $$0I:(DE-Juel1)VDB793$$d31.10.2010$$gICG$$kICG-4$$lAgrosphäre$$x1 000057155 970__ $$aVDB:(DE-Juel1)89909 000057155 980__ $$aVDB 000057155 980__ $$aConvertedRecord 000057155 980__ $$ajournal 000057155 980__ $$aI:(DE-Juel1)IBG-3-20101118 000057155 980__ $$aUNRESTRICTED 000057155 981__ $$aI:(DE-Juel1)IBG-3-20101118
