Oklahoma State University.
Responsibilities: Planning, budgeting, design and implementation of applied and basic field and laboratory research in soil fertility and plant nutrition. Development of sensor-based technology for variable rate application of N and P fertilizers for crop production. Continuation of 14 long-term N-P-K experiments, development of networking systems for field experiments addressing nutrient use efficiency in wheat, alfalfa, cotton, sorghum, peanuts, soybeans, bluestem, bermudagrass and corn. Advancement of environmentally safe fertilization practices for continuous production systems, evaluation of alternative production practices, development of alternative statistical methods for field experimentation, and characterization of N transformations in soils. Teaching graduate level 'soil plant nutrient cycling and environmental quality' and junior-senior level 'topics in precision agriculture', project proposals for outside funding, and supervision of field and laboratory experiments conducted by graduate students.
