Food-Based Composts Provide More Soil Fertility Benefits Than Cow Manure-Based Composts in Sandy Soils

Abstract: Nutrient concentration and availability vary substantially among composts depending on the materials used and the production process. Composts produced from agricultural operations typically utilize animal wastes such as manures, whereas composts produced in urban areas mainly incorporate food and yard waste. Our objective was to assess how different composts affect nutrient availability and cycling, mostly carbon (C) and nitrogen (N). In a laboratory incubation, we compared three composts derived from cow man… Show more

“…The high release rate of TN in CF compost can be attributed to the low initial C/N ratio. Similar observations on increase in TN due to treatment of food waste compost was reported by Kelly, et al [20] with 11%. They also observed that compost derived from food waste provided more N benefits than cow manurederived composts and have greater nutrient value.…”

“…At 270 days there was still a very high increase rate with 551, 350 and 269% in CF, VW and LP treatments respectively. Kelly et al [20] reported a similar increase of 127% in AP due to treatment of food waste compost in soil. Manirakiza and Seker [21] reported an increase of AP by 48.7mgkg -1 in soil due to application of compost.…”

“…137 Zeolite was added with oil-degrading and multibacterial consortium in a composting experiment and revealed that oil-degrading bacterium degraded the oil-rich postconsumption food waste (PCFW) better than the multifunctional bacterium consortium or without inoculum as well as shortened the decomposition time by 20 days. 138 The compost from FW is nutrient-rich as compared to vermicompost 139 and thus would be a potential material for soil amendment.…”

“…Diverting food waste from landfills to anaerobic digestion and composting could reduce methane emissions and enable the recovery of nutrients and energy in usable forms (USEPA, 2021a,2021b). Both processes produce soil amendments—digestate and compost, respectively—that can be applied to agricultural lands to support soil health and fertility (Cheong et al., 2020; Kelley et al., 2020; Roy, 2017). Anaerobic digestion provides the additional benefit of recovering usable energy from food waste in the form of biogas (F. Xu et al., 2018).…”
