Honorable Forum: I'm looking for references on soil atmosphere or climate (the distinctions between the two terms is a bit foggy to me). My primary interest at the moment is in condensation of free or capillary (available) water on soil particles as a result of temperature change, i.e., the movement or transfer of water vapor from one part of the soil mass to another when gravitational and capillary movement of water has stopped. I am especially curious about changes in humidity within the soil mass during "drought" periods and the role of this phenomenon in plant physiological processes (water uptake of free or capillary water or conductivity of water vapor into plant roots or mycelia), including fungi, as well as effects on soil fauna. Of course, I am also concerned about the ecological/evolutionary effects of this process.
In particular, I am interested in studies of wildland soils as opposed to agricultural soils, but any studies that explain the fundamental processes will be welcome. I will interpolate as necessary if all I can get are agricultural studies. I'll appreciate your comments and suggestions. WT
