Year-long Analysis of the Water Quality of White Horn Brook

Sponsor: Thomas Boving (Geological Sciences)

Water is the foundation for all life on earth and is the most vital resource on this planet. Despite this, oceans and waterways all over the world are being polluted and exploited in ways detrimental to their fundamental hydrologic functions. For instance, excess nitrate levels can lead to eutrophication which gives rise to harmful algae blooms. Low pH can cause the breakdown of CaCO3 exoskeletons of organisms, such mollusks. High temperature variations are major stressors to living things and can cause …

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 …
