The last meeting of the PlantSoil group of the Spanish Society of Terrestrial Ecology on plant-soil interactions was held in Antequera (Málaga). In there, we presented the URAGAN project on the reduction of human health risk associated with the use of organic amendments of animal origin in agriculture, and the preliminary results obtained in the the microcosm experiment on the dissemination of antibiotic resistance as a consequence of fertilizing with amendments in different composting stages.
