Additionally, congratulations go to two members of our group who placed in the graduate student oral presentation contests:


Soil surfactants and critical soil moisture content

By Ryan Schwab

Water-repellent soils are one of the challenges faced by golf course superintendents. This phenomenon can cause localized dry spots (Figure 1), which are areas of wilted turfgrass struggling from a rootzone with poor water infiltration, poor water retention, and non-uniform flow of water among other important soil characteristics. The potential or severity of soil water repellency may increase once the soil dries down to a specific level.
