World Soil Day 2020

World Soil Day (WSD) is held annually on 5 December as a means to focus attention on the importance of healthy soil and to advocate for the sustainable management of soil resources for a food-secure future. The date of 5 December for WSD was chosen because it corresponds with the official birthday of H.M. King Bhumibol Adulyadej, the King of Thailand, who officially sanctioned the event

Soil is home to more than 1/4 of our planet's biodiversity. Yet, we only know 1% of this universe. There are more living creatures in a single teaspoon of healthy soil than there are people on Earth. Soil organisms are responsible for many critical ecosystem processes on which humans depend: from supporting plant growth, to storing carbon and being a vast reservoir for pharmaceuticals.

But soil biodiversity is under threat. Half of the topsoil on the planet has been lost in the last 150 years, with a staggering 26.4 billion tons of soil lost each year, a rate that is 10 times faster than soil is being replenished. Soil erosion is also a significant yet largely overlooked contributor to carbon emissions.

In support of this year's theme - 'Keep soil alive, protect soil biodiversity' - Elsevier presents a curated, open access collection of over 60 journal articles to raise awareness of the importance of maintaining healthy soil ecosystems.



Pedobiologia, Volume 66, January 2018, Pages 36-42

Advancing SDG 15, this article explores enzyme and MicroResp diversity as indicators of soil quality.

Pedobiologia, Volume 66, January 2018, Pages 11-17

Advancing SDG 15, this article explores how common phycophagy is among collembolan species inhabiting extreme habitats and a temperate spruce forest. The authors conclude that soil phototrophic microorganisms should be considered an important channel for nutrient cycling in soil communities.

Pedobiologia, Volume 69, July 2018, Pages 1-10

Advancing SDG 15, this article studies the effect of acid-activated biochars on soil microbial enzyme activities (EA) in comparison to several different control treatments without activated biochar.

Pedobiologia, Volume 71, November 2018, Pages 20-30

Advancing SDG 15, this article focuses on the fungal communities of Scots pine aged between 7 and 87 years.

Geoderma, Volumes 167–168, November 2011, Pages 178-187

Plant diversity was shown to influence the N cycle, but plant diversity effects on other nutrients remain unclear. Advancing SDG 15, this article tested whether plant species richness or the presence/absence of particular functional plant groups influences P partitioning among differently extractable pools in soil, P concentrations in soil solution, and exploitation of P resources (i.e. the proportion of total bioavailable P in plants and soil that was stored in aboveground biomass) by the plant community in a 5-year biodiversity experiment in grassland.

Geoderma, Volume 312, 15 February 2018, Pages 6-16

Advancing SDG 15, this article examined three species endemic in New Calendonia to determine if some plant species are more useful for stabilizing soil aggregates and thus reducing erodibility.

Pedobiologia, Volume 69, July 2018, Pages 29-33

Advancing SDG 15, this article explores the carbon budget and the carbon stocks in major compartments of the soil food web.

Pedobiologia, Volume 74, May 2019, Pages 43-53

Advancing SDG 15, this article highlights ecological drivers of soil oribatid assembly at multiple scales.

Geoderma, Volume 323, 1 August 2018, Pages 65-73

Advancing SDG 15, this article explore modifications to water infiltration and surface texture of Haplic Luvisols by two ant species.
