Modeling the Potential Productivity of Urban Agriculture and Its Impacts on Soil Quality Through Experimental Research on Scale-Appropriate Systems

Urban Farm DB summary

This long-term replicated trial in Rhode Island evaluated the yield performance and soil quality impacts of four small-scale food production systems over three summer growing seasons. While total marketable food yields (2.22 to 2.96 kg m-2) were modest compared to biointensive agriculture (4.64 kg m-2), individual crop yields often exceeded regional and national averages without soil quality loss. The study addresses a lack of experimental research on urban agriculture and provides a framework for normative research, offering more reliable yield estimates for modeling urban production potential.
