Permafrost microbes may further accelerate climate change

,
Permafrost microorganisms, explains a study by Colorado State University, are also able to break down polyphenols. A finding that could force an upward correction of CO2 emission previous estimates

In the USA, a predictive model shortens soil test timing

,
Researchers at the University of Arkansas have developed a predictive model of soil structure and organic matter content that halves the overall testing time
In China, the addition of biochar to agricultural soils has generally increased the organic carbon content of soil aggregates.

Here is how biochar promotes the sequestration of organic carbon

,
Biochar promotes the formation of soil aggregates and, with them, carbon sequestration, a research explains. In some Chinese farmland, the presence of the substance has increased by 60 per cent
Water that does not evaporate first passes through the canopies and carries nutrients to the soil through leaves and branches or along the stems. Photo: Stuart Rankin CC BY-NC 2.0 DEED Attribution-NonCommercial 2.0 GenericStuart Rankin CC BY-NC 2.0 DEED Attribution-NonCommercial 2.0 Generic

This is how canopies affect the distribution of soil nutrients

,
Chinese research analyzed nutrient precipitation dynamics by identifying and quantifying soil enrichment mechanisms in relation to climate and vegetation

How organic carbon accumulates in acidified forest soils

,
A study by the Chinese Academy of Sciences reveals how forest soil acidification promotes both mineral protection and plant-derived carbon accumulation
Mountain meadows are one of the largest sinks of soil organic carbon in Central Europe. Photo: crash71100 CC0 1.0 DEED CC0 1.0 Universal Public Domain DedicationPhoto: crash71100 CC0 1.0 DEED CC0 1.0 Universal Public Domain Dedication

Mountain meadows are threatened by climate change

,
Rising temperatures drives the loss of humus in mountain meadows and, with it, the release of CO2 into the atmosphere. This is reported in a study by the Technical University of Munich

Roots and A.I. offer carbon storage solutions

,
According to Alliance of Bioversity International deeper roots boost carbon sequestration while artificial intelligence enables more accurate measurements of carbon storage

Microbes are a key resource for slowing desertification

,
Chinese investigation shows how microbes play a relevant role in countering desertification through their ability to manage essential soil nutrients

Cyanobacteria are amazing biofertilizers for soil

,
According to a U.S. study, cyanobacteria or "blue-green algae" can be used to produce a biofertilizer suitable for iron-poor soils, thus turning into a valuable natural resource for farmers

In peatlands, climate change supports the degradation of organic carbon

,
An experiment shows that in peatlands all organic soil components decompose more rapidly when temperatures are higher
