Des scientifiques découvrent une gigantesque réserve mondiale de carbone dans le sol
Le carbone du sol fait généralement référence à la composante organique, appelée carbone organique du sol (COS). Cependant, il existe également un composant inorganique, appelé carbone inorganique du sol (SIC), qui est souvent composé de substances comme le carbonate de calcium. Le SIC s’accumule généralement dans les régions arides et moins fertiles, ce qui laisse penser que ce n’est pas important.

Caribbean startups are turning excess seaweed into an agroecology solution
* Sargassum, a type of brown macroalgae, has been inundating beaches across the Caribbean since 2011. It comes from the Sargasso Sea in the Atlantic Ocean.
* The seaweed has harmed Caribbean economies and human health, making it a national emergency in some island-nations.
* Over the past decade, entrepreneurs and scientists have found ways to turn sargassum into nutrient-rich biofertilizers, biostimulants and other organic products to boost agricultural yields while cutting back on chemicals.
* But there are hurdles to scaling the industry, including sargassum’s inconsistent arrival, heavy metal content and fast decomposition rates.

Forests - Forest types - Afforestation - Carbon sequestration - Study
1 April 2024
Careful selection of forest types in afforestation can increase carbon sequestration by 25% without compromising sustainability - Tomoko Hasegawa, Shinichiro Fujimori, Akihiko Ito & Kiyoshi Takahashi
Afforestation is a major carbon dioxide removal technology but can negatively affect food and land systems. Here, we used an integrated assessment model to quantitatively demonstrate how the selection of forest type to use in afforestation could increase global carbon sequestration without compromising global food and land sustainability. Our findings indicate that if a carbon-intensive forest type is selected, afforestation would increase carbon sequestration by 25% compared to the level assuming the native forest type. At the same time, if implemented inappropriately at a large scale, afforestation would worsen the economy, food, and land systems due to decreased land efficiency in carbon removal compared to bioenergy with carbon capture and storage, leading to increased land expansion for carbon removal, higher food prices, and increased risk of hunger. These results suggest the need to implement carbon-intensive forest types with complementary measures to reduce the adverse impacts on food and land sustainability.

* Despite billions of US dollars put toward rescue efforts, citrus production numbers are the lowest they have been since the Great Depression.
* Scientists from Argentina are now testing the agroecological method of push-pull pest management using an organic plant-hormone solution to lure pests away from citrus crops and toward “trap crops” instead.
* Proponents hope push-pull management, first developed in East Africa, could be part of the solution and lessen dependence on pesticides.

Soil - Fungal community composition - Forest carbon storage - European continent - Study
16 March 2024
Fungal community composition predicts forest carbon storage at a continental scale - Mark A. Anthony and all
Forest soils harbor hyper-diverse microbial communities which fundamentally regulate carbon and nutrient cycling across the globe. Directly testing hypotheses on how microbiome diversity is linked to forest carbon storage has been difficult, due to a lack of paired data on microbiome diversity and in situ observations of forest carbon accumulation and storage. Here, we investigated the relationship between soil microbiomes and forest carbon across 238 forest inventory plots spanning 15 European countries. We show that the composition and diversity of fungal, but not bacterial, species is tightly coupled to both forest biotic conditions and a seven-fold variation in tree growth rates and biomass carbon stocks when controlling for the effects of dominant tree type, climate, and other environmental factors. This linkage is particularly strong for symbiotic endophytic and ectomycorrhizal fungi known to directly facilitate tree growth. Since tree growth rates in this system are closely and positively correlated with belowground soil carbon stocks, we conclude that fungal composition is a strong predictor of overall forest carbon storage across the European continent.
