Physical properties controlling water repellency in synthesized granular solids verfasst von Y. Saulick, S. D. N. Lourenço, B. A. Baudet, S. K. Woche, J. Bachmann Abstract The wettability of granular solids such as soil is known to depend primarily on two factors: their inherent chemistry and their physical properties, such as their particle size, particle shape and surface roughness.

Effect of soil drying on mucilage exudation and its water repellency A new method to collect mucilage verfasst von Mutez A. Ahmed, Maire Holz, Susanne K. Woche, Jörg Bachmann, Andrea Carminati Abstract Despite the importance of mucilage for soil plant relations, little is known about the effect of soil drying on mucilage exudation.

Capturing water repellency cessation time by means of characteristic time method verfasst von Nasrollah Sepehrnia, Jörg Bachmann Abstract Persistence of water repellency is a significant physical key factor that governs water infiltration into unsaturated soil. We investigated water and ethanol infiltration using the characteristic time method CTM , repellency index RI , and the contact angle CA behavior for a compre...

Occurrence and spatial pattern of water repellency in a beech forest subsoil verfasst von Jörg Bachmann, Jiem Krueger, Marc O. Goebel, Stefanie Heinze Abstract Most recent studies on soil water repellency WR were limited to the humous topsoil or to shallow subsoil layers slightly below the main root zone to approximately 0.5 m depth.

Isothermal and nonisothermal evaporation from four sandy soils of different water repellency verfasst von J. Bachmann, R. Horton, R. R. Van Der Ploeg Abstract Soil water evaporation is an important component of the surface energy balance.

Occurrence and spatial pattern of water repellency in a beech forest subsoil verfasst von Jörg Bachmann, Jiem Krueger, Marc O. Goebel, Stefanie Heinze Abstract Most recent studies on soil water repellency WR were limited to the humous topsoil or to shallow subsoil layers slightly below the main root zone to approximately 0.5 m depth.

Effect of vegetation and its succession on water repellency in sandy soils verfasst von Lubomir Lichner, Vincent J.M.N.L. Felde, Burkhard Büdel, Martin Leue, Horst H. Gerke, Ruth H. Ellerbrock, Jozef Koll r, Marek Rodn , Peter urda, N ndor Fodor, Ren ta S ndor Abstract Vegetation and its succession can change the parameters of soil water repellency SWR due to the change in amount and composition of soil organic matter.

Applicability of ethanol for measuring intrinsic hydraulic properties of sand with various water repellency levels verfasst von A. Lamparter, J. Bachmann, M. Deurer, S. K. Woche Abstract Many soils worldwide show water repellency to some degree. Soil water repellency SWR is known to alter hydraulic processes. Particularly in water repellent soils a decreased water infiltration rate can be observed.

Water repellency enhances the deposition of negatively charged hydrophilic colloids in a water saturated sand matrix verfasst von Marc O. Goebel, Susanne K.

The effect of temperature induced soil water repellency on transient capillary pressure water content relations during capillary rise verfasst von A. Reszkowska, J. Bachmann, A. Lamparter, E.

Transport, retention, and release of Escherichia coli and Rhodococcus erythropolis through dry natural soils as affected by water repellency verfasst von Nasrollah Sepehrnia, Jörg Bachmann, Mohammad Ali Hajabbasi, Fereidoun Rezanezhad, Lubomir Lichner, Paul D. Hallett, Mark Coyne Abstract Microbial transport in soil affects pathogen retention, colonization, and innoculant delivery in bioremediating agricultural soils.

An efficient method for the collection of root mucilage from different plant species A case study on the effect of mucilage on soil water repellency verfasst von Ina Maria Zickenrott, Susanne K. Woche, Jörg Bachmann, Mutez A. Ahmed, Doris Vetterlein Abstract Root mucilage may play a prominent role in understanding root water uptake and, thus, there is revived interest in studying the function of root mucilage.
