| Abstract/Contents: | "Utilizing urban vacant land for growing food crops can promote access to healthy food in low income neighborhoods. However, soil health and quality are major concerns for urban agriculture in post-industrial cities. Replacing existing soil with top-soil from a neighboring area is the most common solution applied, during which no attention is given to the health of the soil organisms being transported. Nematodes form an important and diverse component of the soil food web, with presence across multiple trophic levels, offering the most comprehensive insight into the structure and function of food webs. Previous studies showed that due to intensive disturbance, nematode food webs in urban areas had significantly lower structural complexity and lacked higher trophic guilds (predatory and omnivorous species), thus severely limiting the ecosystem services potential of the soil. We tested a new approach to improve the soil food web structure in targeted vacant lots, to restore the full spectrum of ecosystem services provided. We hypothesized that the missing nematode trophic guilds (along with associated soil organisms) in the soil food web can be transplanted/reestablished using small soil cores (9cm dia, 5cm deep) when coupled with specific organic amendments. Field trials of core transplantation into turf grass plots (1.5 m X 1.5 m) resulted in a significant increase in the structure index over a period of 6 weeks. Positive results from this study could eliminate the need for large-scale topsoil replacements in urban gardens and will pave the way for establishment of sustainable and safe urban food production systems." |
