“…Vegetable crop yields at North Fremantle Social Farm and Glyde-in Garden Gnomes are likely affected by high soil salinity. The high EC reading of raised beds in Murdoch Community Garden, North Fremantle Social Farm, Earthwise Community and Glyde-in Garden Gnomes may be caused by salts and nutrients present in the compost, with these compounds also released by adding compost to the soil (Carmo et al, 2016;Lück, 2015). Plant residue-derived compost upon decomposition can release acids or acid-forming compounds, which can react with slightly soluble salts existing in the soil and be converted into a more soluble form, increasing soil EC (Sarwar et al, 2008).…”

Community gardens, as common spaces where people gather to grow food, help foster public health, greener urban environments, life‐long learning and vibrant communities. However, despite being promoted as sustainable horticulture and conservation agriculture, their soil health and carbon (C) sequestration potential, with implication for climate change mitigation, remains underexplored. This study assessed soil samples collected from raised beds (gardening area) and adjacent bare ground (control) at six community gardens in the Perth metropolitan area, Australia. These sites covered three soil mapping units (SMUs): calcareous deep sands, coloured sand and pale sands The soil in raised beds exhibited superior characteristics than surrounding urban soil including lower bulk density, higher pH buffering capacity, available nutrients including nitrogen (N), phosphorus (P) and potassium (K), cation exchange capacity (CEC), total C and microbial biomass. Notably, we estimated that raised bed soils accumulated significant levels of C in the top 10 cm layer (0.55 kg/m2 or 5.5 T/ha). Our findings also indicate no significant heavy metal contamination in any of the community garden soils. Although the global area of community gardens is marginally small, these results suggest they hold potential for carbon sequestration, especially in urban and peri‐urban environments. The improved soil health and C storage potential in community garden soil are largely attributed to the regular application of compost produced within the community gardens.
