The study, conducted in the forests of Yunnan Province, demonstrated how altitude-driven environmental changes shape the genetic potential for phosphorus mineralization in the soil. At the same time, soil pH acts as a constant filter, limiting the microbial community capable of performing this vital function across different landscapes.

Elevation, pH, and calcium are key factors in the phosphorus cycle

,
A Chinese study has identified the key factors influencing the distribution of available phosphorus in tropical and subtropical forests, by modelling the genetic potential for phosphorus mineralization in soil
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
In Southeast Asia, deforestation and land conversion have released more carbon and greenhouse gases than any other activity over the past two decades. Photo: Pok Rie Pexels free to usePok Rie Pexels free to use

Deforestation has made Southeast Asia a net source of carbon

,
In the first two decades of the century, according to a Japanese study, the forests in the area released more carbon than they stored. Fires, peatland degradation, and fossil fuels are making things worse
The construction of new roads is a particularly significant sign of deforestation. However, many of them are difficult to identify.

A map of future roads helps fight deforestation

,
A team of Australian researchers managed to develop a deforestation risk index based on the probability that an area may be affected by new road construction
In China, vegetation restoration has reduced soil erosion from nearly 17.7 tons per hectare to less than 14 between 1990 and 2020. Image: PickPik Royalty-Free photoPickPik Royalty-Free photo

Vegetation restoration has curbed soil erosion in China (at least so far)

,
According to research, soil regeneration in China has significantly reduced land erosion over the last 30 years. More extreme rainfall in the future, however, will raise the risks
In wetlands, diversity improves both nitrogen retention and removal processes, but has a more pronounced effect on the latter. Photo: shankar s. Attribution 2.0 Generic CC BY 2.0 DeedPhoto: shankar s. Attribution 2.0 Generic CC BY 2.0 Deed

Plant biodiversity promotes nitrogen removal in wetlands

,
Greater plant diversity is positively correlated with the process of transforming nitrites and nitrates into nitrogen gas released into the atmosphere, according to a Chinese study. This discovery could contribute to planning the restoration of wetlands
Over four decades, the planet's soil has become greener overall. But it has also become drier. Photo: Jialiang Gao Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 DeedJialiang Gao Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 Deed

Greener but less wet: a Chinese study reveals the global soil paradox

,
Research: in forty years, two-thirds of vegetated areas have become greener, but half of those also experienced considerable soil drying. Crucial factor: increased evapotranspiration

A Chinese study has quantified 20 years of carbon sequestration in wetlands

,
Research by the Chinese Academy of Sciences reveals that wetlands sequestered an average of one billion tons of carbon per year in the first two decades of the century. Seventy percent of this capture takes place in tropical areas
Understanding how rice maintains productivity with the support of the microbiome under conditions of nutritional deficiency can help develop new strategies in precision agriculture.

Root bacteria help reduce the environmental impact of rice cultivation

,
A Japanese study has identified some bacteria in rice roots that are responsible for nitrogen fixation and can spread in soil without fertilizers or pesticides. This helps the plant adapt and grow

Extreme heat waves are becoming longer and more frequent

,
A study on abnormal heat phenomena, involving researchers from the United States and Chile, reveals an acceleration of the trend on a global scale. Tropical regions are the most affected
