Research
My research program focuses on soil fertility and plant nutrition in for both annual and perennial crop plants grown in irrigated systems.
- Monitoring technologies for predicting nitrogen need non destructively
- Development of site specific nutrient management strategies in potato, grape and cranberry
- Nutrient management in juice and wine grape
- Natural and induced changes in nutrient chemical dynamics in cranberry systems
