The effect of temperature and wetting–drying cycles on soil wettability: Dynamic molecular restructuring processes at the solid–water–air interface

open access: yesEuropean Journal of Soil Science, Volume 72, Issue 5, Page 2180-2198, September 2021., 2021
Abstract The impact of heat treatment and wetting–drying cycles on the wetting properties of sandy forest soils was explored. Topsoil and upper subsoil were sampled at three beech forest sites in northern Germany. The air‐dried soils were treated at 20, 40 and 80°C for 24 h, with materials treated at 20°C serving as reference.
