Soil and Plant Tissue Analyses: What You Need to Know
With persistent drought conditions and irrigation use in many vineyard regions in Oregon the questions of soil and vine nutrition continue to be hot topics among growers. Join Dr. Alec Levin of Oregon State University as he moderates an in-depth discussion on vineyard soils and plant nutrition with soil and plant scientists. Soil scientist with Red Hill Soils, Andy Gallagher, will present on vineyard soil testing revealing what your soil is saying to you and how to address it. Joined by USDA research plant physiologist, Dr. Paul Schreiner, who will present an understanding of soil and plant tissue analyses for vine and soil health optimization.
Dr. Alexander (Alec) Levin is a viticulturist at the Southern Oregon Research and Extension Center (SOREC) and assistant professor in the Department of Horticulture at Oregon State University. He also is a core faculty member of the Oregon Wine Research Institute (OWRI), and serves as the chair of the Grape Genetics, Physiology and Management working group in the International Society for Horticultural Science. Dr. Levin completed his Ph.D. in horticulture and agronomy at UC Davis investigating physiological differences in drought responses among several red wine grape cultivars. Since 2016, he has been leading the Southern Oregon viticulture research and extension program at SOREC, located in the heart of the Rogue Valley. Dr. Levin conducts applied viticultural research focused in the fields of grapevine water relations and ecophysiology, and vineyard irrigation management. His ultimate research goals are to develop sustainable vineyard management practices tailored to production goals.
Dr. R. Paul Schreiner is a Research Plant Physiologist at the USDA-ARS, Horticultural Crops Production and Genetics Improvement Research Unit in Corvallis, OR. Paul conducts research on grapevine physiology with a focus on plant nutrition, and the functioning of roots and arbuscular mycorrhizal fungi. He received a BS in Biochemistry from Penn State University in 1985, and a PhD in Plant Physiology from Penn State University in 1992. Paul has worked on mycorrhizal fungi since 1988 and on grapevine physiology since 1999. He has published more than 60 peer-reviewed research papers, and more than 50 other publications.
Andy Gallagher is a Certified Professional Soil Scientist and Soil Classifier with 37 years of experience in soil mapping and soils research. His business Red Hill Soils is based in Corvallis, and has been providing soil mapping and soil management consulting for Oregon Vineyards for the last 25 years. Working with clients in site selection and consulting on a wide range of soil issues are Andy’s specialties. Andy also works with growers of other high value crops including hops, truffles, hazelnuts and organic vegetables His research interests have revolved around soil including winesoils and terroir, soil health and carbon stocks, nutrient management, no-tillage and precision agriculture, earthworms in agricultural ecosystems, watershed management, runoff and erosion. Born and raised in the Midwest, Andy got his soils education at the University of Wisconsin. He holds an MS in soil science from the UW-Madison and a BS from the UW-Stevens Point. Andy has field experience with geology and soils in ten states from the Midwest, the Southeast Coastal Plain and Piedmont and the Pacific Northwest.
