SOUL project gets started, five EU countries will test new bio-based products

, ,
The initiative brings together 16 partners for the development and field testing of new-generation products designed to biodegrade in the soil at the end of their life cycle, thus minimizing their environmental impact
Grasslands currently store about one-third of the planet's terrestrial carbon. However, they are subject to different dynamics and the impact of livestock.

Ending grazing reduces stable carbon levels in grasslands

According to British research, undisturbed grasslands accumulate more fast-cycle carbon in the soil than those with grazing livestock. However, they also have lower levels of stable carbon
In Kerala, in southern India, natural forests store an average of 16.61 grams of carbon per kilogram of soil, compared to 11.82 grams in teak plantations.

Natural forests beat artificial regeneration in carbon sequestration

,
In intact forests, soil carbon levels are significantly higher than in areas being restored by tree planting, where higher soil acidity reduces sequestration capacity

Forest soil in Germany has offset carbon losses from trees during drought

,
The discovery comes from the Thünen Institute: between 2018 and 2020, German forest soil stored more carbon than expected, almost entirely offsetting the losses associated with plant mortality
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
Today only 7% of the original surface area of continental peatlands has remained intact, and their climatic boundaries are changing. Photo: SiberianJay Attribution-ShareAlike 4.0 International CC BY-SA 4.0 DeedSiberianJay Attribution-ShareAlike 4.0 International CC BY-SA 4.0 Deed

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
By distinguishing between stable and unstable forms of carbon accumulation, the microbial pump-based assessment system allows for a more reliable evaluation of sustainable soil management practices. Photo: Rain Photography Pexels free to useRain Photography Pexels free to use

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)
