Urban cultivation in allotments maintains soil qualities adversely affected by conventional agriculture

Urban Farm DB summary

This study compared soil quality indicators (soil organic carbon storage, total nitrogen, C:N ratio, and bulk density) in urban allotments, surrounding agricultural land, and other urban greenspaces in a typical UK city. Allotment soils showed 32% higher soil organic carbon concentrations and 36% higher C:N ratios than pastures and arable fields, and 25% higher total nitrogen and 10% lower bulk density than arable soils. The study reported no significant difference in soil organic carbon concentration between allotments and urban non-domestic greenspaces, but it was higher in domestic gardens beneath woody vegetation.
