Mycorrhizal fungi and soil factors influence toxic element uptake in urban grown produce
2023Logan Bowdish, Adalie Duran, Justin Richardson, Eric Vukicevich · Urban Agriculture & Regional Food Systems · United States
In an urban community farm, this study evaluated how crop identity, harvested tissue, and soil factors—including arbuscular mycorrhizal (AM) fungi—affect crop uptake of lead and arsenic. Lead uptake increased with lower soil pH and lower soil phosphorus, greater AM fungal colonization was associated with greater lead uptake, while more fungal storage vesicles related to less arsenic uptake into leaves.

CSA & TeikeiEconomicsHealthWelfareSchool Gardens and the Urban Child
2023Angela Oulton, Susan Jagger · · North America
A discourse analysis of historical school garden texts in North America reveals that school gardens have not been welcoming or accessible to all children, despite persuasive research on the positive effects of nature-based learning. Historically, school gardens were used to serve adult agendas, including containing urban children, assimilating marginalized groups, and creating laborers, thereby reinforcing patriarchal, colonial, white supremacist, and eugenic aspirations. This study explores how these discourses culturally constructed childhoods and influenced children.
