The States General of the Soil return to Rimini

,
The date is for November 9th. Objective: to create an opportunity for discussion between the academic and institutional actors, involved in defining best practices in favor of the soil. Two sessions and dozens of experts are scheduled

Invasive plants can remove excess salt at the roadsides

,
Some plants help clear roadsides of salt and pollutants, a research has found. But their contribution is not enough. De-icing applications need to be reduced

Pesticides persist in bee pollen, study says

,
An Irish study shows that pollen from several bee species retains traces of toxic substances from neonicotinoids. And researchers are concerned
The term "permafrost" refers to the type of perennially frozen (but not necessarily ice-covered) soil found in some cold regions. Photo: NPS Climate Change Response CC BY 2.0 DEED https://www.flickr.com/photos/npsclimatechange/27759123542Photo: NPS Climate Change Response CC BY 2.0 DEED

Superficial permafrost could (almost) disappear by 2100

,
By the end of the century, near-surface permafrost may exist only in the highlands of eastern Siberia, the High Arctic and northern Greenland. As was the case 3 million years ago
Characterized by semi-arid biomes, the Caatinga Forest in eastern Brazil is one of the richest areas in the world in terms of biodiversity. Photo: NiaziGamer CC BY-SA 4.0 DEED Attribution-ShareAlike 4.0 InternationalNiaziGamer CC BY-SA 4.0 DEED Attribution-ShareAlike 4.0 International

Climate change puts 40 percent of biodiversity in eastern Brazil at risk

,
In the Catinga forest rising temperatures threaten to destroy nearly half the biodiversity by 2060, a Brazilian study says. Ecosystem services are under threat
The influence exerted on the population composition of microorganisms comes from the ability of earthworms to influence soil structure, pH, nutrient availability and organic matter. Photo: benketaro Attribution 2.0 Generic (CC BY 2.0)benketaro Attribution 2.0 Generic (CC BY 2.0)

Earthworms are changing Canadian forests

,
Invasive species of earthworm affect microbial composition by altering overall soil conditions, Canadian research explains. Influencing nutrient and carbon cycling
In many cities in the United States and Canada, municipal waste incinerators were largely shut down in the 1970s in the face of growing concerns about air pollution. Photo: Fraser, Clayton B.

Waste incineration leaves a heavy legacy in soils

,
Where waste was once burned, higher concentrations of lead are detected in the soil, says research from Duke University. With obvious health consequences

Urbanization promotes increasing emissions from the soil

,
As a result of urbanization, soil nitrous oxide emissions increase 153%, according to a new study. At the same time, the ability to absorb methane is reduced
Under drought conditions, microbes produce more atmospheric compounds than they consume. Photo: Flore de Preneuf / World Bank Attribution-NonCommercial-NoDerivs 2.0 Generic (CC BY-NC-ND 2.0)Flore de Preneuf / World Bank Attribution-NonCommercial-NoDerivs 2.0 Generic (CC BY-NC-ND 2.0)

Here’s how drought stress alters soil function in the rainforest

,
Drought progressively reduces the ability of soil to consume biogenic volatile organic compounds according to a German study. The emission intensifies after soil rewetting

Solar farms may encourage soil erosion in U.S.

,
Virginia Tech researchers will analyze erosion risk in the state's solar installations. In the U.S., the problem is real. But several solutions are available
