Physical soil attributes in areas under forest/pasture conversion in northern Rondonia, Brazil

Alan Ferreira Leite de Lima et al.

Summary: Overgrazing and poorly productive soils are the main causes of physical degradation in pasture areas. This study evaluated the impacts of converting forests to pastures in northern Rondonia, Brazil, on the physical attributes of the soil. The findings showed that the conversion led to a decrease in soil aggregates and compaction, a reduction in porosity, and a decrease in the accumulation of organic carbon in the soil. Additionally, the study found greater spatial variability of physical attributes in the environment with mombaca grass, which may be attributed to higher grazing and trampling intensity.

Aboveground Biomass, Carbon Sequestration, and Yield of Pyrus pyrifolia under the Management of Organic Residues in the Subtropical Ecosystem of Southern Brazil

Lucas Jonatan Rodrigues da Silva et al.

Summary: Organic residues management, such as compost and mulching, can significantly influence plant traits, soil properties, and carbon cycling. In a 16-year subtropical P. pyrifolia field, the application of compost was found to promote plant growth, biomass, yield, and above- and belowground carbon density. Meanwhile, mulching treatment improved soil organic carbon stock. These findings highlight the importance of organic residue practices in enhancing plant production and carbon sequestration.

Drivers and trends of global soil microbial carbon over two decades

Guillaume Patoine et al.

Summary: Soil microorganisms play a crucial role in maintaining soil functions and services, but our understanding of their spatial-temporal dynamics is still limited. This study analyzes the temporal trends in soil microbial biomass carbon and identifies the main drivers of change, revealing the areas sensitive to environmental factors. The research finds that global soil microbial biomass carbon has decreased by approximately 3.4% over the past 20 years, with increasing temperatures being the main driver of decline in the northern regions.

Carbon Dynamics in Humic Fractions of Soil Organic Matter Under Different Vegetation Cover in Southern Tocantins

Josue Luiz Marinho Junior et al.

Summary: A study in the Cerrado region of Tocantins, Brazil revealed that the Eucalyptus sp. area had higher levels of total carbon in soil humic fraction compared to other areas. The stocks of fulvic acid, humic acid, and humin in Eucalyptus sp. area were significantly higher than in native forest, pasture, and agriculture areas. Soil from the Eucalyptus sp. area showed great potential to increase carbon storage in soil humic fractions.
