Contamination & food safetyHealthOrganic cycleApplying recovered nutrients and pruning waste to enrich and regenerate agricultural soils in urban agriculture: Effects on emissions and yield of spinach and sweet potato
2026Guido Evangelista, Juan David Arosemena, Gaia Stringari, Joan Romanyà, Xavier Gabarrell, Francesco Orsini, Gara Villalba · Agriculture Ecosystems & Environment · Global
This study evaluated the application of 150 t ha-1 of ramial chipped wood (RCW) to degraded peri-urban agricultural soils, comparing its effects on yield, soil health, and greenhouse gas emissions for spinach and sweet potato. Spinach grown with RCW showed the lowest productivity (1.16 – 0.32 kg m-2) among treatments, while sweet potato achieved the highest yield (1.72 – 1.99 kg m-2). High RCW doses initially led to higher CO2 emissions but significantly reduced N2O emissions for spinach (from 0.36 kg ha-1 to 0.07 kg ha-1) and enhanced soil organic carbon and nitrogen stocks for sweet potato, indicating agronomic and environmental trade-offs.

2025Piaopiao Ke, Beñat Olascoaga, Pasi Kolari, Outi Tahvonen, Sami Haapanala, Tom Kokkonen, Leena Järvi, Markku Kulmala, Anna Lintunen · Urban forestry & urban greening · Finland
A year-round eddy covariance and soil chamber measurement in an urban allotment garden in southern Finland showed it functioned as a net CO₂ source (0.69 kg m⁻² yr⁻¹) despite 77% vegetation cover. High respiratory emissions (4.7 kg m⁻² yr⁻¹) exceeded photosynthetic uptake (4.0 kg m⁻² yr⁻¹), likely due to elevated soil organic carbon (13.4 ± 8.7%) and high soil C:N ratio from management amendments. These findings challenge assumptions about urban gardens as inherent carbon sinks and suggest carbon-smart management practices are needed.
