Summary: Microplastics can impact microbial communities and carbon cycling in agricultural soils. This study investigates the effects of microplastics on the decomposition of soil organic matter and bacterial community succession. The results show that microplastics initially reduce CO2 efflux but subsequently promote it, possibly due to enhanced enzyme activities and shifts in bacterial diversity.

Summary: The study found that high intensity soil heating reduces soil carbon sink strength by affecting microbial anabolism, while lower intensity heating has minimal impact on microbial biomass accumulation and carbon use efficiency. Addition of pyrogenic organic matter (PyOM) to soils resulted in similar microbial biomass accumulation compared to uncharred organic matter, but lower CO2 emissions.

Summary: The conversion of natural forest to artificial vegetation results in decreased soil moisture, microbial carbon and nitrogen, bacteria, fungi, enzymatic activities, organic carbon, total carbon, total nitrogen, NO3-, total phosphorus, available phosphorus, cations, and cation exchange capacity, while increasing soil bulk density, pH, and NH4+. The loss of desirable soil properties is more likely to occur in warmer regions over time due to the greater consumption of soil nutrients and harder soil conditions. Stand age influences soil carbon and nitrogen ratios, as well as ratios of bacteria to fungi following natural forest conversion.

Summary: The study focused on soil quality and fertility after restoration in southwestern Saudi Arabia, showing that sandy loam was the dominant textural class and pH levels varied in different areas. Restoration practices led to changes in SOM and EC levels, with different effects observed in AJ, QRC, and SK sites. Further research is needed to explore the long term effects of restoration activities on land rehabilitation.

Summary: The study examined the impact of 30 years of decadal prescribed burning on carbon and nitrogen in plants, detritus, and soils in coniferous forests in the Sierra Nevada mountains, USA. The results showed that fire reduced forest floor carbon and increased the resistance of remaining mineral soil organic matter to decomposition. Fire also led to lower microbial respiration rates and reduced enzyme activity, suggesting a decrease in decomposition and an increase in soil organic matter that is resistant to decay.

Summary: The study found that forest stand density has different effects on soil carbon and nitrogen contents depending on tree species. It was also found that density increase can affect the decomposability and stability of soil organic matter. The tree species also showed different susceptibility to elevated carbon input. This study highlights the importance of considering stand density and tree species in predicting carbon losses from forest soils.

Summary: The main objective of this study was to determine the role of deadwood in the formation of soil organic matter fractions in mountain forest soils. By comparing the properties of decomposing deadwood and the soils beneath it, conclusions were drawn about the influence of deadwood on soil organic matter fractions and carbon storage in different climate conditions. Heavily decomposed deadwood had a stronger impact on soil organic matter stabilization, while the light fraction of organic matter was more sensitive to deadwood effects. The release of nutrients from decaying wood stimulated enzymatic activity in the influenced soils.

Summary: Biochar-derived dissolved organic matter (BDOM) plays important roles in soil ecosystem by influencing soil properties and providing nutrients to soil microbes. BDOM can either enhance or suppress the growth of certain soil microorganisms depending on its composition and labile organic compound content. This review focuses on the impact of BDOM concentration, feedstock biomass type, and pyrolysis temperature on soil microbial functioning, community structure, and enzymatic activity. Results indicate that feedstock type and pyrolysis temperature affect BDOM characteristics and its interaction with soil microbial communities. Plant-based biochar produced at lower pyrolysis temperatures often contains more aliphatic BDOM, while higher pyrolysis temperatures yield more aromatic BDOM. BDOM from plant biochar has higher specific ultraviolet absorbance (SUVA) and humification index (HIX) compared to manure-based biochar. The SUVA and HIX of BDOM positively correlate with total fatty acid methyl ester content, but negatively correlate with abundances of actinomycetes, arbuscular mycorrhizae, and fungal communities. However, long-term experiments are needed to fully understand the environmental fate of BDOM in biochar-amended soil and its interaction with soil organic matter and microorganisms.

Summary: Soil organic matter contains more carbon than global vegetation and the atmosphere combined. Accessing this carbon source requires the removal of protective layers and the enzymatic or chemical cleavage of plant polysaccharides. Soil-feeding animals have evolved the ability to mineralize recalcitrant soil organic matter through symbiotic associations with gut microbes.

Summary: The application of bamboo leaves and its biochar affected soil CO2 emissions and temperature sensitivity of SOC mineralization. The key factors related to SOC mineralization rate included WSOC, MBC, O-alkyl C, alkyl C contents, as well as beta-glucosidase and dehydrogenase activities. The study highlighted the potential of using pyrogenic organic matter to reduce SOC mineralization and maintain soil carbon stock in subtropical forest ecosystems.

Summary: Agricultural management practices can impact microbial populations and ecoenzymatic activities. This study investigated the effects of biochar and nitrapyrin on ecological stoichiometry and microbial nutrient limitation in a wheat-canola rotation. The results showed that biochar increased microbial biomass carbon, nitrogen, and phosphorus, while nitrapyrin had no effect. Biochar and nitrapyrin had contrasting effects on ecoenzymatic stoichiometry, with biochar decreasing and nitrapyrin increasing the ratio of phosphorus to nitrogen. Overall, biochar from manure compost can be beneficial in alleviating phosphorus limitations and promoting microbial growth in agricultural systems.

Summary: The distribution of soil organic carbon (SOC) in subsoil is more heterogeneous than in topsoils. The rhizosphere soil plays an important role in substrates input into deeper soil layers and contains higher SOC content, microbial biomass, and microbial community diversity. The rhizosphere is a hotspot for microbial activity, especially in the subsoil, and is crucial for carbon turnover in soil.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
