      Dr. Smith is a soil biochemist in the Land Management and Water Conservation Research Unit at Pullman, Washington.   His area of research is the development of novel techniques and new principles which apply to nutrient cycling and plant nutrient management to minimize nutrient losses, and to develop nutrient budgets for conservation tillage systems for the production of small grain and legume crops in the Pacific Northwest.   His research emphasizes the development of methodology and theory for tracing major nutrients into plants from crop residues, soil, and fertilizer sources as affected by soil properties and management practices.   The goal of his research is to identify crop and soil management systems which significantly increase nutrient use efficiency by crops while minimizing the negative impacts of nutrients on soil quality, air and water resources and environmental quality.   Dr. Smith’s research includes carbon and nitrogen cycling, nitrogen transformations in subsurface soils, soil quality analysis, trace gas production from terrestrial ecosystems, shrub-steppe ecosystems, groundwater chemistry and hydrology, microbial energetics and the use of radioactive and stable isotopes in plant and soil studies.
