Soil microbes will release 40 percent more CO2 by 2100

,
Climate change is increasing the respiration of soil microbes and related CO2 emissions. A phenomenon, says a Swiss study, set to accelerate between now and the end of the century

Chinese study unravels the mysteries of biocrusts

,
Researchers have shown how surface biocrusts protect subsoil microorganisms by increasing their diversity and stability which benefit the soil
"Terra preta" ('black soil' in English) is found although in small amounts in the Amazon and is part of the macro category of so-called black soils, known for their fertility.

The secret to Amazon regeneration lies in black soil

,
According to Brazilian research, the valuable black soil found in parts of the Amazon retains unique characteristics that promote the rapid recovery of deforested land

Subsoil carbon is particularly vulnerable to climate change

,
International study shows how, at one meter depth, soil gives up more than one-third of its pyrogenic carbon after experiencing a 4°C temperature rise in less than five years
Biochar is especially useful in limiting the effects of soil salinization. A phenomenon which is prevalent in Bangladesh where about one-third of agricultural land is in coastal areas.

Biochar provides relief for saline soils in Bangladesh

,
Biochar promotes tomato crop yields in salt-affected soils, a research conducted in Bangladesh has found. Effects on carbon sequestration are also positive

UK, two thirds of soils show nutrient deficit

,
An analysis by the independent laboratory NRM: as a result of the degradation, wheat crops show 10% less nitrogen and 25% less phosphorus. Thousands of soil samples extracted from UK farmland
In Canadian forests, increased tree species diversity produces growth in soil carbon and nitrogen.

Variety of trees promotes carbon and nitrogen sequestration

,
An increase in the number of tree species stimulates greater carbon and nitrogen sequestration, Canadian research explains. But biodiversity is in decline. Promoting it means mitigating climate change and reducing land degradation
