I have 70% Extension and 30% research statewide responsibilities for soil nutrient management and plant mineral nutrition. The goal of my research and extension program at Clemson is to improve the sustainability of South Carolina’s Agroecosystems in terms of profitability, environmental stewardship, and social acceptance. Specifically, I focus on developing nutrient management practices and precision agriculture technologies for major crops in order to maximize economic returns and reduce the potential of nutrient losses to the environment, particularly nitrogen and phosphorus. In my extension activities, I seek to provide relevant, unbiased, and timely research-based information that is transformed into usable knowledge to benefit my clientele. In addition to my research and extension responsibilities, I also advise graduate students and supervise undergraduate students, research scholars, temporary workers, and technical support staff.

 Research Interests

My goal is to develop a nationally recognized externally funded applied research program, which includes the development of technologies capable of enhancing current nutrient management strategies resulting in increased yields and nutrient use efficiency.

Objectives of my research program are:
1) Verifying and updating fertilizer recommendations for various crops in South Carolina.
2) Assess the impact of including cover crops in South Carolina cropping systems on nutrient management and soil health.
3) Identify a set of biological soil health tests that are easy to use and stable over time in determining nutrient recycling using pre-plant soil sampling;

 Extension and Outreach

My extension program provides current soil fertility management information to county extension agents, crop consultants, producers, fertilizer dealers, environmentalists, and researchers.

Objectives of my extension program are:
1) Demonstrate the agronomic and economic benefits of using best fertilizer management practices through on-farm trials and facilitate the grower adoption of these practices.
2) Provide local information to clientele about the use of cover crops and their management practices so to diversify SC cropping systems through on-farm demonstrations;
3) Provide need-based training to extension teams through workshops, field days, email alerts, extension articles, and media reports regarding various soil and crop management challenges and issues and how to address them.
