Urban Farm DB summary
The PROSTOCK project aimed to spatially assess the potential of recycling organic waste (exogenous organic matter, EOM) to improve soil organic carbon stocks (SCS) in peri-urban agricultural areas. It also evaluated the impacts of EOM use on greenhouse gas emissions and nitrate leaching. The Versailles Plain and Alluets Plateau (221 km²) were chosen as the study region, with field and lab measurements collected from over 250 point locations. The project advanced the use of imaging data for estimating topsoil organic carbon content (SOC) from soil reflectance spectra, but found that medium spatial resolution multispectral satellite images do not discriminate changes in SOC resulting from EOM applications.
