Mixed forests are less vulnerable to soil acidification

,
The Chinese study: in larch and broad-leaf forests, nitrogen deposition has no significant impact on soil chemistry. Therefore, in the fight against acidification, the creation of mixed forests could be effective

The impact of wildfires on understorey and biodiversity rises in Australia

,
In areas affected by wildfires, which are increasingly severe and frequent in Australia as in the rest of the planet, there is a decrease in plant diversity
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
