The secret to Amazon regeneration lies in black soil

,
According to Brazilian research, the valuable black soil found in parts of the Amazon retains unique characteristics that promote the rapid recovery of deforested land

Subsoil carbon is particularly vulnerable to climate change

,
International study shows how, at one meter depth, soil gives up more than one-third of its pyrogenic carbon after experiencing a 4°C temperature rise in less than five years

Microbes give new hope for soil remediation in Alaska

,
Alaska, which has always struggled with cases of oil contamination, may find new solutions in phytoremediation. According to researchers at the University of Fairbanks, grasses and fertilizers shape microbial communities responsible for disposing of toxic substances

Based on soil sounds, ecoacoustics helps us protect forests

,
A study highlights the potential of ecoacoustics: by listening to ecosystem sounds, it is possible to monitor and restore forest soil health. And better assess the effectiveness of interventions
The Avcılar neighborhood in Istanbul stands on land particularly prone to liquefaction, a widespread phenomenon in several urban areas of Turkey. Photo: Maderibeyza Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)Maderibeyza Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)

Soil liquefaction is still a big issue in Turkey

,
There is more than just the force of nature behind the widespread building collapses experienced during earthquakes in Turkey. Poor construction practices and bad choices in fact foster soil fragility

Landowner amnesty has hampered land restoration in the Amazon

,
Since 2012, more than 50 percent of deforestation in the Amazon has occurred in "protected" areas in private hands, a U.S. study has found. Amnesty that excluded managers from restoration obligation was crucial

Mediterranean forests face desertification risk

,
In the past, forests around the Mediterranean Sea partly turned into steppes within a few decades as precipitation rates changed. Today, a German research explains, this scenario could happen again

Habitat diversity helps insects address climate change

,
Insects adapt to global warming with different energy management, a German research has found. Microhabitat diversity, which is crucial, is declining due to land-use changes
Per- and polyfluoroalkyl substances are typically found in fluorinated pesticides that contain one or more fluorine atoms in their molecular structure and are considered particularly effective in combating plant pests.

Worrying data in the U.S. on PFAS contamination in soil

,
In New Hampshire, the presence of fluorine-based substances was detected in all soil samples taken by researchers. These products, known as PFASs and contained in pesticides, are typically difficult to dispose of
