The focus of Bart's research program at NPARL will be to work collaboratively with other NPARL scientists to investigate alternative irrigated cropping strategies and to investigate their impact on weed management, soil quality and conservation, water and nutrient use efficiency, and economic and environmental sustainability.




Prior to joining the USDA-Agricultural Research Service in 2005, Bart was a Soil Scientist at the University of Wyoming Powell Research and Extension Center where his research focused on improving efficiency of N fertilization practices for sugarbeet and dry bean using variable rate technology, improved application timing, and proper N source selection.  While at the University of Wyoming, Bart also investigated the interaction of micronutrient management and weed control practices in sugarbeet.  Before beginning his work in Wyoming Bart worked for two years as a post-doctoral research associate at the University of Nebraska West Central Research and Extension Center.  While there, he conducted research on use of industrial byproducts (sugarbeet processing lime and coal fly ash) for liming agricultural soils, micronutrient management in corn, and variable rate N management.  Bart's graduate work ranged from investigating the iron deficiency stress mechanism of soybean to the effect of different management practices on soil N transformations and N use efficiency.
