Unlocking complex soil systems as carbon sinks: multi-pool management as the key

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: June 15, 2023

Much research focuses on increasing carbon storage in mineral-associated organic matter (MAOM), which may persist for centuries to millennia. However, MAOM-targeted management is insufficient because the formation pathways of persistent soil are diverse and vary with environmental conditions. Effective must also consider particulate (POM). In many soils, there potential enlarging POM pools, can over long time scales, be a direct precursor MAOM. We present framework context-dependent strategies that recognizes soils as complex systems conditions constrain MAOM formation.

Root Exudates Mediate the Processes of Soil Organic Carbon Input and Efflux

Plants, Journal Year: 2023, Volume and Issue: 12(3), P. 630 - 630

Published: Jan. 31, 2023

Root exudates, as an important form of material input from plants to the soil, regulate carbon and efflux plant rhizosphere soil play role in maintaining nutrient balance whole ecosystem. exudates are notoriously difficult collect due their underlying characteristics (e.g., low concentration fast turnover rate) associated methodological challenges accurately measuring root native soils. As a result, up until now, it has been quantify organic most studies. In recent years, contribution ecological effects have paid more attention. However, mechanism mediated by rarely analyzed comprehensively. this review, main processes influencing factors demonstrated. Soil minerals microbes key roles processes. The allocation is influenced relationship between functional traits. Compared with quantity response exudate quality environmental changes affects function more. future, different availability will be quantified, which helpful understand sequestration.

Mineral-mediated stability of organic carbon in soil and relevant interaction mechanisms

Eco-Environment & Health, Journal Year: 2024, Volume and Issue: 3(1), P. 59 - 76

Published: Jan. 3, 2024

Soil, the largest terrestrial carbon reservoir, is central to climate change and relevant feedback environmental health. Minerals are essential components that contribute over 60% of soil storage. However, how interactions between minerals organic shape transformation stability remains poorly understood. Herein, we critically review primary mechanisms, including sorption, redox reaction, co-precipitation, dissolution, polymerization, catalytic reaction. These interactions, highly complex with combination multiple processes, greatly affect through following processes: (1) formation or deconstruction mineral-organic association; (2) oxidative minerals; (3) polymerization (4) varying association according mineral transformation. Several pieces evidence related turnover during interaction in real eco-environment then demonstrated. We also highlight current research gaps outline priorities, which may map future directions for a deeper mechanisms-based understanding storage capacity considering its minerals.

Soil organic carbon loss decreases biodiversity but stimulates multitrophic interactions that promote belowground metabolism

Abstract Soil organic carbon (SOC) plays an essential role in mediating community structure and metabolic activities of belowground biota. Unraveling the evolution communities their feedback mechanisms on SOC dynamics helps embed ecology soil microbiome into cycling, which serves to improve biodiversity conservation management strategy under global change. Here, croplands with a gradient were used understand how metabolisms decomposition linked diversity, composition, co‐occurrence networks encompassing archaea, bacteria, fungi, protists, invertebrates. As decreased, diversity prokaryotes eukaryotes also but network complexity showed contrasting patterns: increased due intensified niche overlap, while that decreased possibly because greater dispersal limitation owing breakdown macroaggregates. Despite decrease stocks, capacity was enhanced as indicated by enzyme activity enzymatic stoichiometric imbalance. This could, turn, expedite loss through respiration, particularly slow‐cycling pool. The dominantly driven multitrophic negative (competitive predator–prey) associations, fostered stability metacommunity. Interestingly, abiotic conditions including pH, aeration, nutrient exhibited less significant role. Overall, this study reveals need for C resources across levels maintain functionality declining results loss.
