Professor Emeritus, Plant Nutrition and Soil Fertility

Program Areas

  • Teaching

    My teaching program focuses on teaching basic and applied concepts and practices for sustainable agricultural and urban land management. I teach courses on campus and via the web. My main course is “Sustainable Agricultural and Urban Land Management” taught each Fall. The teaching programs support student teaching goals of the department and College.

  • Research

    Departmental Research Areas:

    • Management of Nutrients, Pesticides, and Wastes

    Research focus:
    My research program has focused on optimizing nutrient management for farm profitability and environmental sustainability. The program is built around the general area of nutrient best management practices. Projects covered include soil test calibration, determining fertilizer requirements and nutrient management practices for various crops, and measuring environmental impact of nutrient management programs. The research program trains graduate students and contributes to the general scientific knowledge base through publications in scientific journals.

  • Extension

    My Extension education program has been built around my research program and focuses on training county extension agents in the newest technologies and practices of nutrient best management practices. We conduct on-farm demonstration programs with farmers and county agents. I make educational presentations at many farmer workshops and conferences. I write extension factsheets containing information on nutrient best management practices.
