简介

My research focuses on development of fertilizers and soil fertility management approaches that optimize plant and human nutrition while protecting environmental quality. Nitrogen fertilizer is estimated to contribute about two-thirds of greenhouse gas emissions attributed to crop production. But without fertilizers, crop yields would be halved, a loss that humanity cannot afford. Therefore, we are working towards development of fertilizers that can be produced locally, moving towards a truly local agriculture and avoidance of fossil fuel usage during shipping. We are currently focused on two types of farming systems: organic, diversified vegetable farms in Colorado and smallholder farms in Ethiopia.
