Seventy percent of agricultural land in Europe contaminated with pesticides

, ,
University of Zurich findings: seven out of ten crop soils in Europe are polluted with pesticides that have a significant impact on the biodiversity of microbial communities. Fungicides are responsible for more than half of the residues detected
Still largely unknown, soil microbiome include more than half of all existing species, including nematodes, plants, fungi, bacteria, archaea, and other microbial species. Photo: Carol M.

US soil microbiome under investigation by researchers

,
A group of researchers led by Johns Hopkins University is exploring the US microbiome by collecting soil samples from urban and rural locations to identify genetic connections between the environment and microorganisms
The study has important implications for climate change, as tropical forests are essential carbon sinks for the planet.

Nitrogen doubles the regeneration speed of tropical forests

,
When provided with adequate nitrogen tropical forests can recover from deforestation twice as fast as they would under normal circumstances, a research led by the University of Leeds has found
The construction of new roads is a particularly significant sign of deforestation. However, many of them are difficult to identify.

A map of future roads helps fight deforestation

,
A team of Australian researchers managed to develop a deforestation risk index based on the probability that an area may be affected by new road construction
The importance of this technique lies in its applicability to cereal crops, which are fundamental to global food security. Photo: Pixabay Creative Commons CC0 1.0 Universal Public Domain Dedication licensePixabay Creative Commons CC0 1.0 Universal Public Domain Dedication license

Researchers have turned cereal plants into pollution sensors

,
US researchers have developed a genetic circuit that activates upon the presence of contaminants in cereal crops by inducing grasses to produce a visible pigment
The surface of ferrihydrite has mixed areas of positive and negative charges, allowing it to attract both negatively charged substances such as phosphates and positively charged substances such as metal ions.

This is how iron minerals promote soil carbon sequestration

,
Iron oxide minerals trap more than a third of the organic carbon in soil. Among them, a study explains, ferrihydrite uses different strategies to capture different compounds
The study, which involved the universities of Aalborg and Vienna, is particularly significant for a country with a strong agricultural tradition such as Denmark. Photo: Jane Tierney Attribution 2.0 Generic CC BY 2.0 DeedJane Tierney Attribution 2.0 Generic CC BY 2.0 Deed

Denmark has mapped national soil microbiome

, ,
The study, which involved the universities of Aalborg and Vienna, holds particular significance for a country with a strong agricultural tradition such as Denmark. The degree of habitat disturbance, the authors explained, affects microbial profiles
The results of the Chinese study revealed divergent trends: soil moisture decreased between 1980 and 2023, but the trend reversed after 2010. Image: U.S. Department of Agriculture (USDA) CC0 1.0 Universal CC0 1.0 DeedU.S. Department of Agriculture (USDA) CC0 1.0 Universal CC0 1.0 Deed

Measuring global soil moisture is more difficult than expected

, ,
A Chinese study has proposed a new double validation method to compare humidity data from nearly a thousand stations. Highlighting and solving typical spatial representativeness errors

Plants use engineering to beat soil compaction

,
An international study reveals the engineering mechanisms that allow roots to penetrate compacted soil. A plant hormone plays a key role. The findings open up new opportunities for crop breeding

Through electrolysis we can neutralize (and enhance) soil contaminants

,
The Federal Institute of Technology in Zurich has developed an electrochemical method for breaking down contaminants, recovering harmless salt and other useful products for the chemical industry. This frees the soil from the presence of stable toxins
