TL;DR: In this article, the Wilhelmy plate method (WPM) and modified capillary rise method (MCRM) were tested on 24 soils and the results showed that both WPM and MCRM are reliable for determining contact angles and particle surface energy over a wide range of porous material wettabilities.

TL;DR: In this article, a modified sessile drop method was proposed for measuring the initial contact angle of powdered or granular material, which is made by placing a layer of uniform soil particles onto adhesive tape, adding droplets of deionized water, and reading off the contact angle at the three-phase boundary line with a goniometerfitted microscope immediately after placing the drops on the soil sample.

TL;DR: In this article, the authors studied the significance of soil wettability with respect to both SOM mineralisation and aggregate stability in a loess-derived Gleyic Luvisol, either used as cropland or as grassland.

TL;DR: In this paper, the authors investigated the dynamics of contact angle due to variation of the water potential and found that the contact angle increased as water potential increased to a specific level, and then decreased again when water potential reached a certain level.

TL;DR: In this article, the authors investigated contact angles and wetting properties as a function of depth for a wide range of agricultural and forest soils in Germany, and concluded that a coarse texture favours, in combination with other factors (mainly pH), hydrophobic SOM.
