Laboratory, greenhouse, and micro/small-plot, and field studies are conducted in various locations with various cooperators. Stable C and N isotope technology is used to understand basic soil and biological processes. Agronomic and horticultural crops are used, depending on study objectives. Water management includes sprinkler and furrow irrigation. Nutrient management (especially N) techniques include models, GIS, remote sensing, yield monitoring, and quick field tests to increase nutrient use efficiency (NUE). Low/no-till are incorporated into soil and crop rotation management practices. Bioremediation studies are conducted on methods to remove excess contaminant using innocuous C sources. Evaluations are made of practices to enhance microbial mediation, protect the environment, and remediate contaminated soil and groundwater. Plant-microbe interactions will be studied in the field and laboratory using advanced technologies to reduce the effects of pests on crop yield. The applicability of models and decision tools to provide real-time, on-farm management approaches will be evaluated.
