In the U.S., turfgrass, including domestic lawns, covers more than 160 thousand square kilometers and host an important biodiversity. Photo: rawpixel free public domain CC0 imagerawpixel free public domain CC0 image

Less intensive management of lawns promotes soil biodiversity

,
A study shows how less intensive management of lawns, especially of those surrounding homes, allows to support many below-ground species that contribute to the balance of the ecosystem
Unlike traditional manure, frass is low in pathogens and rich in key elements such as nitrogen, phosphorus and carbon. Photo: Forest & Kim Starr Attribution 3.0 United States CC BY 3.0 US DeedForest & Kim Starr Attribution 3.0 United States CC BY 3.0 US Deed

Insect waste can be a viable alternative to traditional fertilizers

, ,
A study from U.S. has highlighted the soil benefits of applying frass, the mix of insect waste products that can be turned in a resource in a circular economy model
Tree crops such as olives, coffee, fruit trees, and cocoa currently cover more than 183 million hectares worldwide and contribute to the protection of global biodiversity. Photo: Maxence Attribution 2.0 Generic CC BY 2.0 DeedMaxence Attribution 2.0 Generic CC BY 2.0 Deed

Perennial woody crops help preserve biodiversity

, ,
Some plants, such as coffee, cocoa and fruit trees support wide biodiversity. But science and agricultural policies, researchers write, tend to underestimate their potential
Scientists have discovered light receptors that help plants conserve energy as they grow. In this way, even when casually covered with soil, the seedling can elongate further until it emerges from the soil again.

With the help of light we can improve plant growth

,
An American study provides new information on how plants detect light and grow. The finding could help make more resilient crops

The Planet’s fastest water cycle runs through plants

,
It takes only five days for a drop of water stored in a cultivated plant to complete its outward journey to the atmosphere, a study explains. Land use alters the speed of the process
Rapid degradation of organic soils is increasingly affecting the Montérégie, one of the main agricultural regions in Canada. Photo: Axel Drainville Attribution-NonCommercial 2.0 Generic CC BY-NC 2.0 DeedAxel Drainville Attribution-NonCommercial 2.0 Generic CC BY-NC 2.0 Deed

In Canada, scientists are studying natural solutions against soil degradation

,
Researchers at Laval University in Quebec are exploring new methods against soil deterioration in Montérégie, a key agricultural region in Canada. Under investigation are straw, shavings and polyphenols
PFAS are found in many products such as firefighting foams, paints, pesticides, coatings, and food packaging.

Cleaning up Europe from PFAS would cost 2 trillion over 20 years

,
The estimate is included in an investigation coordinated by the French newspaper Le Monde into the spread of PFAS in the Continent. Producers' lobby under attack
In the future, the large northern forests of Canada, Alaska, and Siberia may become denser with trees and more vulnerable to wildfires. Photo: Jasper Hunter Pexels free to usePhoto: Jasper Hunter Pexels free to use

More homogeneity and fires are coming for boreal forests

,
Secondo uno studio della Wageningen University le foreste dell'emisfero settentrionale saranno sempre più simili tra loro a causa dei cambiamenti climatici. In questo modo aumenterà anche il rischio di incendi boschivi

Crop diversification supports nitrogen sequestration (but not carbon)

,
Diversifying rotations does not promote carbon storage but increases nitrogen availability with positive impact on soil and climate, a Iowa University study has found

Efficient use of nitrogen is needed to protect environment and health, says FAO

,
Nitrogen, the UN agency remarks, is an essential element but also a contaminant. Its intake to the soil is likely to quadruple by the end of the 21st century
