Letter from the Editor-In-Chief
Welcome to the first issue of volume nine of the Spanish Journal of Soil Science, which contains articles on fertility and soil quality in places as diverse as Mexico, Indonesia, Argentina and Nigeria.
These interesting articles deal with these issues from different points of view, from soil biology and ecology (interactions between symbiotic organisms, functional genomic groups), to the adaptation of fertilization practices to water-saturated environments and sustainability of management practices including fertilization.
As always, on behalf of the editorial team, we thank the authors for sending the manuscripts, the guest editors for their rigor in the selection and review of manuscripts, the referees for the quality of their reviews, and the team Universia for its professionalism.
