We visited (February 1st, 2018) a Biocomposting Plant in Artajona (Navarra, Spain) where they prepare high quality (even, ecological) composts from different types of residues. We are currently most interested in the use of organic amendments in agriculture. In particular, we are investigating the links between these organic amendments and the possible dissemination of antibiotic resistant bacteria and antibiotic resistant genes. Our aim is to select the best amendments for agricultural purposes, from the point of view of carbon sequestration and improvement of soil fertility and quality, while reducing the risks of ecosystem degradation through the introduction of (emerging) contaminants.
