1. Introduction Soil hydrophobicity, a property of soils that repel water, is commonly seen in the upper soil layers. Soil hydrophobicity can either naturally exist— typically due to the type of vegetation—or occur after wildfires [1,2,3]. Wildfires can cause soil hydrophobicity via changing the surface chemistry of soil particles caused by particles coated with condensates of volatilized, naturally occurring organic hydrophobic compounds during a high-heat event [1,2].
