An Analytical Solution of Macrodispersivity for Adsorbing Solute Transport in Unsaturated Soils
An analytical solution of macrodispersivity was derived for the adsorbing solute transport in physically and chemically heterogeneous unsaturated soils under the condition of gravity-dominated flow. The unsaturated hydraulic conductivity and water content were treated as spatial random functions. The chemical adsorption was described by a linear equilibrium isotherm, and the adsorption coeffici...
متن کاملOrganic Residues A Resource for Arable Soils
Odlare, M. 2005. Organic Residues – a Resource for Arable Soils. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-6970-8. An increased recirculation of urban organic residues to arable soils has several environmental benefits, but there is a need for reliable test systems to ensure that soil quality is maintained. In this thesis, soil microbial, chemical and physical properties were included ...

متن کاملHigher diversity of Rhizobium leguminosarum biovar viciae populations in arable soils than in grass soils.
The bacterial genetic diversity after long-term arable cultivation was compared with that under permanent grassland using replicated paired contrasts. Pea-nodulating Rhizobium leguminosarum populations were sampled from pairs of arable and grass sites at four locations in Yorkshire, United Kingdom. Isolates were characterized using both chromosomal (16S-23S ribosomal DNA internal transcribed sp...
متن کاملComparison of Pesticide Transport Processes in Three Tile-Drained Field Soils Using HYDRUS-2D
The purpose of this study was to assess the transport of the herbicide bentazone [3-(1-methylethyl)-1H-2,1,3-benzothiadiazin-4(3H)one 2,2-dioxide] in three contrasting tile-drained cultivated field soils subject to otherwise similar experimental conditions. Observed drain discharge rates and chemical concentrations in the drainage water reflected the different transport processes at the three s...
