Microbes may induce soil water repellency through the production of aliphatic constituents as a response to desiccation

Creator:

Chilcote, Emma T.

Abstract:

Soil water repellency may be influenced by microbes whereby they produce aliphatic constituents (non-wetting materials) that coat the soil particles when they are subjected to desiccation stress.

Preliminary Evidence that the Microbial Community may Produce Aliphatic Constituents and Induce Soil Water Repellency as a Response to Desiccation

Creator:

Chilcote, Emma T.

Abstract:

Soil water repellency is one cause of rill soil erosion and overland flow that results in the loss of fertile topsoil. Previous research suggests that since microbial growth depends on temperature/moisture and follows diurnal and seasonal cycles, a biological mechanism would be able to explain the observed seasonality and climate...
