Shifts in controls and abundance of particulate and mineral-associated organic matter fractions among subfield yield stability zones

Increasing soil organic matter (SOM) enhances crop productivity and reduces yield variability. This study, examining nine U.S. farms, found that unstable yield areas had higher particulate organic matter (POM) than stable ones. While mineral-associated organic matter (MAOM) was linked to productivity and soil properties, POM was influenced by decomposition patterns. These findings suggest SOM alone may not ensure yield stability and highlight the role of POM as an indicator of yield stability.

Investigating the effects of climate change and anthropogenic activities on SOC storage and cumulative CO2 emissions in forest soils across altitudinal gradients using the century model

Climate change and grazing impact soil organic carbon (SOC) stocks, increasing with altitude due to cooler temperatures and higher precipitation. Grazing decreased SOC, while manure and liming partially mitigated losses. Because climate change projected SOC losses, particularly at higher elevations, effective forest management is essential to reduce CO2 emissions.

The indoors microbiome and human health

Indoor environments serve as habitat for humans and are replete with various reservoirs and niches for microorganisms. Microorganisms enter indoor spaces with their human and non-human hosts, as well as via exchange with outdoor sources, such as ventilation and plumbing. Once inside, many microorganisms do not survive, especially on dry, barren surfaces. Even reduced, this microbial biomass has critical implications for the health of human occupants. As urbanization escalates, exploring the intersection of the indoor environment with the human microbiome and health is increasingly vital.

Evaluating the near- and long-term role of carbon dioxide removal in meeting global climate objectives

The 6th Intergovernmental Panel on Climate Change (IPCC) Assessment Report lacked sufficient land-sector scenario data to estimate total carbon dioxide removal deployment. Using land-based CO2 removal data from IPCC scenarios, we show afforestation and reforestation are crucial near-term mitigation strategies, contributing around 10% of net GHG reductions from 2020 to 2030. Novel technologies like direct air carbon capture scale by 2050 to balance residual emissions.

Soil organic matter priming: The pH effects

Soil pH significantly influences the priming effects (PE) on soil organic matter (SOM) decomposition. PEs are highest in soils with pH between 5.5 and 7.5, with positive PEs up to 20 times the SOM decomposition at pH around 6.5. Low pH (<4.5) and high pH (>7) result in negative PEs due to suboptimal microbial environments. Short-term pH changes, like soil acidification, affect PE through complexation, oxidation, and enzymatic processes. Long-term pH shifts due to fertilization and land use impact microbial adaptations and PE.

Mycorrhizal fungi modify decomposition: a meta-analysis

Mycorrhizal fungi generally enhance decomposition through the priming effect rather than reduce it via the Gadgil effect. Analyzing 43 studies, mycorrhizal fungi increased substrate decomposition by 6.7%, with variations influenced by substrate C:N ratio and absolute latitude. The type of mycorrhizal fungi did not significantly affect this outcome. These findings suggest a global tendency for mycorrhizal fungi to promote decomposition, potentially impacting soil carbon storage.

Opportunities and challenges for microbiomics in ecosystem restoration

Microbiomics, the study of microbial community structure and dynamics, offers valuable insights into plant-soil-microbe interactions that can enhance ecosystem restoration. Despite its potential, microbiomics can be complex and technology may be inaccessible. Moving beyond basic microbial composition analysis, advanced metaomic tools and non-omic methods like microbial inoculants and biopriming can significantly improve restoration efforts by supporting plant health and community establishment.

Integrated global assessment of the natural forest carbon potential

Forests are crucial carbon sinks, but their C storage capacity is reduced by land use and climate change. This study found a global deficit of 226 Gt in forest carbon storage, primarily in low-impact areas. While forests can't replace emission reductions, conserving, restoring, and sustainably managing diverse forests can significantly help meet climate and biodiversity goals.

The Deep Soil Organic Carbon Response to Global Change

Deep soil organic carbon (SOC) responds differently to global change compared to surface SOC due to weaker biotic controls and stronger mineral influences at depth. This review highlights the need for more research on deep SOC, as current data are limited and often speculative. Incorporating deep soils into studies and models is essential for accurate climate projections and nature-based solutions.
