Professor - Nelson’s lab studies the transformation of Organic Underutilized Resources (OURs) for into valuable agronomic inputs and other products using a Circular Bionutrient Economy (CBE) framework.  One major research area involves co-composting nitrogen-rich urine with carbon-rich agricultural residues, to create horticultural media while simultaneously reducing organic pollutants in urban and aquatic environments.  The team also works on nutrient recovery from urine to produce fertilizers.
