For soil invertebrates, pollution is a worse threat than climate

,
A meta-analysis of more than 600 studies shows that pollution is the most critical factor for the conservation of soil invertebrate biodiversity

Irrigation of rice fields impacts on metal uptake

,
A University of Delaware study highlights the impact of water supply in determining the concentration of arsenic and cadmium in rice plants. But the mechanism is complex and a solution is yet to be found

US researchers test a sensor to assess nutrient loss

,
A research project at the University of Missouri describes the potential of a new instrument to detect the presence of phosphorous- and nitrogen-based nutrients in the soil. An innovation that would pave the way for a more sustainable use of fertilisers

Amazon, land protection initiatives have reduced deforestation by 83%

,
In the first decade of the century, the Amazon experienced a sharp decline in deforestation, explains an international study. But the economic benefits for the indigenous people have been limited. This is why new initiatives are needed

Forests still offset half of global fossil emissions

,
The world's forests, an American study notes, absorb between 3.5 and 4 billion tonnes of carbon each year. Equivalent to "nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019."

Saline and alkaline soils can also contribute effectively to agriculture

,
Although subject to fertility loss, saline soils represent an important agricultural reserve when treated with appropriate restoration techniques. A recent Chinese study examines them
Practices to reduce the release of nitrogen oxides do not slow down the process of restoring the ozone layer in the stratosphere that has been running for years. Photo: NASA ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 DeedNASA ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 Deed

Nitrogen emission cuts do not impact the ozone layer

,
According to a study by the University of Sheffield, nitrogen oxide release reduction practices do not slow down the process of restoring the ozone layer in the stratosphere
Biosolids are a by-product of the wastewater treatment process and can be used as fertilisers as they are rich in nitrogen and phosphorus. Photo: City of Geneva ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 DeedCity of Geneva ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 Deed

US bio-fertilisers are useful but watch out for contamination

,
Used as fertilisers, biosolids produced by wastewater treatment can be very beneficial for the soil. This is also why, according to a study, it is important to analyse their content to prevent contamination phenomena

Denmark bets on biochar for sustainable agriculture

, ,
Biochar in the spotlight: the Danish plan to cut agricultural emissions includes a huge EUR 1.35 billion investment. Chiaramonti (PoliTo): "This solution embraces economic competitiveness and will guarantee multiple benefits"
