Title

Geochemical Analysis of Columbia River Basin Vineyard Soils

Abstract

Soil mineralogy and chemistry are major environmental factors, along with climate and geomorphology, that affect vineyard health, wine production and flavor. My presentation focuses on the mineralogy and chemistry of vineyard soils in the Columbia River Basin. The vineyards in this region are in a unique geologic setting, with iron-rich basaltic bedrock overtopped by silica-rich sediments. The chemistry of local vineyard soils, which are developed within these silica-rich sediments, shows elevated iron levels similar to those in basalt, but the mineralogical data does not show abundant iron-bearing minerals. A better understanding of how soil chemistry and mineralogy are connected will help grape growers better target specific soils for desired properties such as iron content, a key nutrient for plants.
