Urban agriculture is expanding globally and can recycle nutrients from food waste back into the human food system. However, imbalanced compost application can cause nutrient losses and pollution. This dataset is a part of a larger study investigating nutrient dynamics in urban agriculture and quantifying its impact on the Minneapolis-Saint Paul urban ecosystem (NSF #1651361). This study has provided research opportunities for more than 60 undergraduate students and high school interns.
Data archived here are from a 6-year experiment in which replicated garden plots receive annual inputs of different types and amounts of compost, and fluxes of water and nutrients were quantified.
- Quantifying nutrient recovery efficiency and loss from compost-based urban agriculture.
- Investigating potential hydrological ecosystem services in urban gardens through soil amendment experiments and hydrologic models.
