Abstract: A number of trace elements, such as zinc, iron, copper and manganese are essential nutrients. Other trace elements, such as cadmium, can be detrimental to crops, animals and soil microorganisms. Trace element availability to crops and soil organisms will be affected by soil characteristics, crop management, environmental conditions, fertilization and other agronomic practices. The overall objectives of this study are to determine the long- and short-term impacts of fertilization and agronomic management practices on trace element dynamics in crops and soils. This will help us develop practices to enhance crop quality by increasing crop content of essential nutrients while minimizing crop uptake of Cd. We also aim to evaluate microbial bioindicators of Cd contamination and assess the influence of long-term application of Cd in phosphate fertilizer on soil microbial activity. These studies would improve our understanding of the controls of metal transfer from soil to edible plant parts, of interactions of soil microbial activity with trace element accumulation in crops, and of use of soil microorganisms as indicators of trace element stress. Information could also be used for predictive modeling of Cd accumulation as affected by soil and climate characteristics, Cd addition and P fertilization.
