Celebrating Soil: A collection of the latest research

This post is from Journal of Ecology Executive Editor Richard Bardgett.

The UN FAO report on the “State of Knowledge on Soil Biodiversity: Status, Challenges, and Potentialities” was released today, the day before World Soil Day. The report represents a truly global effort by soil scientists and ecologists worldwide and presents the best available knowledge on soil biota, their functions, and the services they provide. It is hoped that the report will contribute to raising awareness of the importance of soil biodiversity as a critical component of the natural system.

Belowground (soil) ecology and its importance for plant population and community dynamics, and ecosystem functioning, is now a major theme in the Journal of Ecology. To celebrate the launch of the “State of Knowledge on Soil Biodiversity” report and World Soil Day 2020, we have put together a selection of papers published in the Journal of Ecology over the last year that have such a focus on belowground ecology.

The papers cover a wide range of topics and collectively contribute to our growing understanding of the functional importance of belowground ecology, including root-associated and decomposer organisms, for plant community dynamics and the functioning of terrestrial ecosystems. In the spirit of World Soil Day, and the “State of Knowledge on Soil Biodiversity” report, these papers also contribute to raising awareness of the importance of living soils as a critical component of terrestrial ecosystems.

We hope that you enjoy these papers and, as ever, welcome submissions of your best papers with a focus on plant-soil interactions to Journal of Ecology.
