A dark future sprouting from sealed soil

Every year in Europe, soils covering an area larger than the city of Berlin are lost to urban sprawl and transport infrastructure. This unsustainable trend threatens the availability of fertile soils and groundwater reservoirs for future generations. A new report made public today by the European Commission recommends a three-tiered approach focused on limiting the progression of soil sealing, mit ...[Read More]

Soils at Imaggeo: fall into litter

Antonio Jordán University of Seville, Spain Description Wet forest soil surface after a rainfall simulation experiment in Los Alcornocales Natural Park, southern Spain. When pores are saturated with water, rainfall does not infiltrate, but a dense litter layer may inhibit runoff for some time. About Imaggeo Imaggeo is the EGU’s online open access geosciences image repository. All geoscientists (an ...[Read More]

Monday paper: Modelling microbial exchanges between forms of soil nitrogen in contrasting ecosystems

Pansu, M., Machado, D., Bottner, P., and Sarmiento, L.: Modelling microbial exchanges between forms of soil nitrogen in contrasting ecosystems, Biogeosciences, 11, 915-927, doi:10.5194/bg-11-915-2014, 2014. The questions It is well known that N and C combine to form organic molecules due to biological processes, although they come together from different pathways. C is extracted from carbon dioxid ...[Read More]

Lightening the clay (II)

  According to the previous post, tetrahedral and octahedral sheets combine to form layers, and we can find two main types of clay structures: structure 1:1 (one tetrahedron sheet and one octahedral sheet) and 2:1 (two tetrahedral sheets and one octahedral sheet). The basic structure of clays is this: Substitutions between cations may occur in the tetrahedral and octahedral sheets, resulting ...[Read More]

Lightening the clay (I)

“The more any indivisible exceeds, the heavier it is”. Democritus (c. 460 – c. 370 BC). What is clay? Clays are particles. Very, very small mineral particles. You cannot see them, you cannot handle them… but unity makes strength. Clays are one of the major mineral components of the soil, whose chemical and physical properties depend on them. The study of soil clay minerals allows a gen ...[Read More]

Turning science into fun games for citizens

By Lindsey Higgins, PhD student at Stockholm University and the Bolin Centre for Climate Research *** In the Wednesday morning debate “Is global economic growth compatible with a habitable climate?” issues of sustainability in a consumptive world were tackled. The four panellists agreed that the goal set by the COP21 meeting in Paris of limiting temperature rise to 1.5°C is unrealistic. Historical ...[Read More]

Paz-Ferreiro, J., Lu, H., Fu, S., Méndez, A., and Gascó, G.: Use of phytoremediation and biochar to remediate heavy metal polluted soils: a review, Solid Earth, 5, 65-75, doi:10.5194/se-5-65-2014, 2014. Soil heavy metal pollution Due to increased extraction and use by various industries, heavy metals come easily to the environment in various ways. Unlike organic substances, heavy metals can not be ...[Read More]
