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

Climate change puts Europe’s last peatlands at risk

,
Currently, a study has found, only 7% of continental peatlands can be considered intact. But climate pressure is increasing, and in the coming years the situation could worsen
Plants and microorganisms are essential for mobilizing phosphorus in the soil, but their effectiveness is influenced by many factors. Photo: pickpik royalty freepickpik royalty free

Plant and microorganism biodiversity increases the availability of phosphorus in the soil

Uno studio cinese rivela i meccanismi che influenzano la capacità di mobilizzazione del fosforo. La fertilizzazione riduce la presenza di elemento assorbibile, la rigenerazione forestale la fa aumentare
Permafrost, the authors note, covers about 17% of the Earth's surface and stores about one-third of the organic carbon in the world's soil. Photo: Boris Radosavljevic Attribution 2.0 Generic CC BY 2.0 DeedBoris Radosavljevic Attribution 2.0 Generic CC BY 2.0 Deed

Here’s how Arctic soil offsets emissions from alpine permafrost

,
Climate change reduces the absorption of greenhouse gases by alpine permafrost but, at the same time, it stimulates CO2 and methane sequestration in Arctic frozen soil, a Chinese study has found. In the first case, global warming potential increases by 13%. In the second, it decreases by 10%

“The new Bioeconomy Strategy is a step forward for the EU’s economic future”

,
David Newman (European Bioeconomy Bureau): "The document acknowledges past mistakes and seeks to correct them, also to avoid missing the train of opportunities that bioeconomy offers". But some aspects are worrying, starting with the lack of market-pull mechanisms to stimulate industrial innovation

Chinese researchers propose a new indicator to assess soil carbon stability

,
Research conducted by the Beijing Academy of Sciences has defined a new framework for assessing the Microbial Carbon Pump in soil. It distinguishes between stable and non stable organic matter (that is more easily decomposed and released)

States General for soil health: circular bioeconomy and soil regeneration are the main issues of 4th edition

,
On November 6, the Ecomondo exhibition in Rimini (Italy) will host the annual event organized by the Re Soil Foundation in cooperation with the event's Technical Committee and the National Bioeconomy Coordination Board. Main themes are circular bioeconomy, regeneration, European policies, and ongoing projects

Soil, climate, and resilience: Bologna hosts the Agricultural Chemistry Winter School

,
The event, organized by organized by the Italian Society of Agricultural Chemistry (SICA) and the University of Bologna will take place in February. Researchers can submit their contributions by December 12. The discussion will focus on sustainable agronomic strategies for the soil-plant-microbiome system

Human activity causes carbon loss in deserts

,
Some human-induced disturbances cause significant carbon loss in the soil of hyper-arid environments, a Chinese study claims. Among the most impactful activities even some practices considered “sustainable” such as seasonal harvesting and irrigation

Plant roots could store more carbon than previously expected at greater depths

,
An American study reveals the existence of a second layer of roots developed by several plant species—often overlooked—that enables additional carbon sequestration
