The Effects Of Silicon Applications On Wear And Drought Stress Of Cool Season Turfgrass, Mike J. Badzmierowski, W. Michael Sullivan

Senior Honors Projects

The ability of turfgrass to maintain quality and functionality during use and drought stress are fundamental to almost all turfgrass environments. A possible mechanism to increase wear and drought tolerance is through the use of supplemental silicon (Si) application. Until recently, Si has received little attention for its role in crop physiology or performance.

While it is recoverable within the plant it is not recognized as an “essential” plant growth component. Si is the second most abundant element in the Earth’s crust; however the majority of soil-Si is bio-geochemically inert. Plants absorb Si exclusively as monosillicic acid, H₂SiO …
