of different organic amendments on soil properties

European soil erosion rates are 1.4 higher than soil formation rates. One of the main drivers of soil erosion is the decline of organic matter. Ironically in some EU countries, two-thirds of the amount of organic residues are landfilled or burned. The biowaste could be used to replenish carbon losses and reclaim degraded soils. Different technologies are used to produce organic amendments (OAs) such as: composting, anaerobic digestion, and fermentation. However, it is not known to what extent OA chemistry is influenced by these technologies and what effects the OAs of different origin have on soil properties. This knowledge could increase C replenishment effectivity and efficiency of OA application. This internship is focused on characterizing and comparing different technologies (composting, fermentation, anaerobic digestion) in soil physicochemical properties.
