Antifreeze salt impacts groundwater year-round

Used in winter to melt ice from roads, salt seeps deep into groundwater until it reaches surface waters. A University of Delaware study illustrates some of the dynamics that affect the phenomenon

Climate and drought are the perfect recipe for disruption (not just) in California

During extended drought periods, soil loses its ability to absorb water, writes The New York Times. When rain occurs, landslide risk increases. A combination of phenomena that climate change makes increasingly frequent
The spread of droughts is linked to rising temperatures. In 2022, the number of times negative monthly precipitation records were broken was the third highest since 1979.

The water cycle has changed. And it favors floods and droughts

Extreme rainfall concentrated in short periods is becoming more frequent just like months characterized by exceptionally low rainfall, scientists from the Global Water Monitor Consortium explain. Growth in duration and severity of heat waves causes "flash droughts" especially in Europe and China

Soil microbes are a valuable resource. Including in case of earthquake

Nitrogen gas emitted by microbes helps stabilize soil by preventing building collapse during seismic events, US research shows. Encouraging this process means avoiding concrete injections while reducing damage to the environment

US potatoes survive pests thanks to lobster shell

Ground shells from lobsters can feed communities of beneficial microbes, creating a line of defense against soil pests. Researchers from University of Maine researchers offer a potential circular solution to safeguard the state's major crop. Which would also avoid tons of waste
In Bangladesh, most soils contain less than 1.5 percent organic matter. This is below the minimum required threshold of 2.5 percent.

Land degradation and food crisis hit Bangladesh

Poor farming practices and dependence on fertilizer have damaged soils in Bangladesh. Nutrient deficiency remains a problem. Use of organic alternatives for soil grows

Soil damage impacts underground wildlife longer

According to a British study, in soil subject to human impact the restoration is slower organisms living underground than in surface. New perspectives in research are needed to protect biodiversity

Herbivores are a surprising ally of climate and soil

Far from being destructive, herbivores contribute to climate change mitigation, according to a new research. Their ability to prevent wildfires and return carbon and seeds to the soil is crucial

Charcoal and poverty fuel deforestation in Tanzania

Deforestation is a result of the national and international economic scenarios, British newspaper The Guardian writes. Environmental policies are ineffective. And the problem affects many African countries

Missing invertebrates: the UK has already lost a third of its earthworms

The biodiversity crisis is also affecting invertebrates. In the United Kingdom, says a study by the British Trust for Ornithology (BTO), the abundance of earthworms in the soil declined by 33 to 41 percent. Poor agricultural practices are a crucial determinant
