2021Chammi P. Attanayake, Ganga M. Hettiarachchi, Mónica Palomo, Gary M. Pierzynski, Blanca Calderón · ACS Agricultural Science & Technology · United States
The effect of limestone and composted manure on lead (Pb) in vegetables and Pb bioaccessibility was assessed in a contaminated urban garden (total Pb ~200 mg kg⁻¹). Amendments did not affect Pb in vegetables or Pb bioaccessibility. Peeling reduced Pb concentration in radish by half, and removing surface dust reduced Pb in leafy vegetables by 40-50%. Daily Pb intake from consuming lettuce and carrot/beetroot from this garden was approximately 1.5 times higher than the interim reference level proposed by the U.S. Food and Drug Administration.

CommunityCompostFood educationFrom urban waste to urban farmers: Can we close the agriculture loop within the city bounds?
2021Rafael Carvalho Machado, Sieglinde Kindl Da Cunha · Waste Management & Research The Journal for a Sustainable Circular Economy · Brazil (Curitiba)
This study investigated Curitiba, Brazil's Urban Agriculture Program (UAP) and its decentralized composting strategy, which aimed to close the agricultural loop within city bounds. Despite training 24 urban farmer communities in composting techniques, the program was unable to achieve this goal. The research, based on secondary data review, interviews, and participatory observation, identified cultural barriers and conflicts among actor roles within the UAP that hindered the adoption of composting practices.
Governance failureCompostCommunityOrganic cyclePolicyQuantifying nutrient recovery efficiency and loss from compost-based urban agriculture
2020Shrestha P., Small G.E., Kay A. · PLOS ONE, 15(4):e0230996 · United States
A study measuring and quantifying nutrient recovery efficiency and loss from compost application in urban gardens. It shows compost often supplies phosphorus far in excess of crop demand, and surplus P can be lost to waterways. The work argues that closing the food-waste-to-compost loop in urban agriculture must be designed for sustainable nutrient management, not just diversion.

2019Gaston E. Small, Paliza Shrestha, Geneviève S. Metson, Katherine Polsky, Ivan Jimenez, Adam D. Kay · Environmental Research Communications · United States
Survey data from 142 gardeners and urban farmers in the Twin Cities Metropolitan Area, USA, characterized phosphorus (P) and nitrogen (N) inputs and harvest, and measured soil P concentrations at a subset of sites. Median application rates were 300 kg P/ha and 1400 kg N/ha, with low nutrient use efficiencies (2.5% for P, 5.0% for N). Garden soils had a median Bray P value of 80 ppm, far exceeding recommended levels, indicating a buildup and potential loss of P and N. Urban gardens, though only 0.1% of land area, constitute one of the largest inputs of P to the watershed.

2019Sally Brown, Ned Beecher · Compost Science & Utilization · United States
This study modeled the carbon benefits and costs of biosolids compost use in King County, Washington. Soil carbon sequestration was highest for use on disturbed soils, such as new housing developments, neglected urban soils, or highway right-of-ways (–1.1 Mg CO2eq per Mg compost), and lowest for use in well-tended yards or other highly maintained landscapes (–0.036 Mg CO2eq per Mg compost). Compost use for tree growth, calculated over a 30-year period, added above-ground sequestration benefits ranging from –1.53 Mg CO2eq per Mg compost for a mature tree grown on a healthy soil to –4.58 Mg CO2eq per Mg compost for a newly planted tree grown on a disturbed site. Assuming a 20 km haul distance, transport costs ranged from 0.005 Mg CO2eq per Mg compost for delivery in a 5 Mg truck to 0.09 Mg CO2eq per Mg compost for pick up in a personal vehicle.

2017Rosalie M. Sharp, Daniel J. Brabander · GeoHealth · United States (Boston)
This study assessed lead (Pb) bioaccessibility, transport, and exposure pathways in urban gardens in Roxbury and Dorchester, MA, in partnership with The Food Project, which brings local farmers into the research. Compost had lower total Pb, lower gastric Pb solubility, and less fine-particle resuspension than soils, with a mean bioaccessible Pb of 265 mg/kg—nearly an order of magnitude lower than soils. Across all matrices, grain sizes under 37 μm held a disproportionate share of bioaccessible Pb, whose isotopic composition pointed to leaded gasoline and leaded paint.
CompostHealthCommunityBiogeochemical characterization of municipal compost to support urban agriculture and limit childhood lead exposure from resuspended urban soils
2017Maia G. Fitzstevens, Rosalie M. Sharp, Daniel J. Brabander · Elementa: Science of the Anthropocene · United States (Boston)
To support urban agriculture and limit childhood lead exposure from resuspended urban soils, this study measured bulk and bioaccessible lead in five types of compost used in Boston urban gardens. Different feedstocks showed unique geochemical fingerprints; bulk lead in compost was a fraction of that in urban soils, yet the bioaccessible fraction exceeded the IEUBK model's default parameters. Based on the observed bioaccessibility, 170 mg/kg total lead in compost yields the same bioaccessible lead as the model predicts for the 400 mg/kg EPA soil benchmark, so risk assessments should treat compost as an urban matrix.

2016Brown S.L., Chaney R.L., Hettiarachchi G.M. · Journal of Environmental Quality, 45(1):26-36 · United States
A review examining the risk that urban soil lead poses to urban agriculture. It concludes that adding compost, organic matter and phosphorus improves soil properties and reduces both the bioavailability of soil lead and fugitive dust, so urban agriculture is unlikely to raise children's blood lead. The findings support the safety of compost-centred soil management in urban gardens.

Food educationCommunityCompostAn Integrated Environmental Analysis Framework for Multi-Functional Urban Food Production Utilizing Nutrient Recycling from Organic Waste Streams
2016William Kort · UWM Digital Commons (University of Wisconsin–Milwaukee) · United States
This study developed a framework for life cycle environmental assessment of urban organic waste utilization in urban agriculture, specifically fruit and vegetable production. Results suggest that a full "urban nutrient cycle" offers significant environmental benefits, including meeting up to 70% of vegetable and 17% of fruit consumption needs in Northern and Eastern U.S. cities, with potential water savings of 10-17% of annual domestic use. Optimizing resource recovery through source separation leads to 1-2% lower wastewater generation and up to 44% greater phosphorus recovery, while overall energy and emissions benefits are 1-2% of a city's annual totals.
