Heavy metals in soil promote antibiotic resistance in bacteria

,
Bacteria isolated in contaminated soils appear to be more antibiotic resistant, says a study from New Zealand. A phenomenon that is still unclear and worrisome because of the risks to human health

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

Excess nitrogen also impacts soil invertebrates and insects

,
A Dutch meta-analysis of 126 studies conducted worldwide illustrates the consequences of nitrogen accumulation for soil microfauna. Effects vary across species. Climate factor

Can seed carriers help regenerate the soil?

,
Created by researchers at Carnegie Mellon University, seed delivery devices pave the way for soil regeneration. But some observers are skeptical

From India to Australia: the bauxite paradox

,
In India, the mining of bauxite, a rock needed for aluminum production, takes land away from agriculture, producing permanent soil damage. But this same resource, paradoxically, may carry with it a solution
The application of statistical models in combination with spectroscopy makes it possible to assess the concentration of different elements in the soil. Photo: Marco Verch Attribution 2.0 Generic (CC BY 2.0)Marco Verch Attribution 2.0 Generic (CC BY 2.0)

Spectroscopy offers new opportunities for soil analysis

,
A research from the University of Katowice opens new perspectives in the field of soil analysis. Through spectroscopy, researchers were able to determine the presence and concentration of key elements in soil

Soil moisture is a key factor in predicting droughts and floods

,
According to a study from U.S., variation in soil moisture is the crucial factor in understanding extreme phenomena such as droughts and floods and Overcoming uncertainty related to climate change
NRM analyzes of thousands of soil samples taken from UK farmland have shown deficiencies in magnesium, phosphorus and potassium. PHOTO: Steven Weeks on Unsplash

UK, two thirds of soils show nutrient deficit

,
An analysis by the independent laboratory NRM: as a result of the degradation, wheat crops show 10% less nitrogen and 25% less phosphorus. Thousands of soil samples extracted from UK farmland
In Canadian forests, increased tree species diversity produces growth in soil carbon and nitrogen.

Variety of trees promotes carbon and nitrogen sequestration

,
An increase in the number of tree species stimulates greater carbon and nitrogen sequestration, Canadian research explains. But biodiversity is in decline. Promoting it means mitigating climate change and reducing land degradation
