Dr. Fiorellino's integrated research and extension program focuses on supporting the productivity and resilience of agriculture in Maryland through performance of producer-centered and producer-driven research. Producer-centered research projects focus on areas that are important for agricultural productivity, such as adaptive nitrogen management, alternative crops, such as industrial hemp, and long-term phytoremediation of soils with high phosphorus concentrations. To mitigate climate change impacts on Maryland farmers, Dr. Fiorellino is evaluating yield impacts of shifting planting dates of agronomic crops based on changing weather patterns. Dr. Fiorellino's producer-driven research is performed in response to concerns that originate with farmers across the state, such as evaluating novel biological products that claim to provide stored nitrogen and examining current potassium recommendations on corn.
