Title: Formation of non-wettable soils...involves heat transfer mechanism

Author: Debano, Leonardo F.

Date: 1966

Station ID: RN-PSW-132

Description: After a wiIdfire, some brushland soils in southern California have been found to include a non-wettable layer. This formation may be the result of hydrophobic material volatilizing and later condensing. In burning experiments, hydrophobic substances from ceanothus litter and non-wettable soil were moved downward into an underlying wettable sand by temperature gradients. The wettable sand acquired a marked resistance to wetting after the burning treatment.
