Particulate organic matter as a functional soil component for persistent soil organic carbon

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: July 5, 2021

Abstract The largest terrestrial organic carbon pool, in soils, is regulated by an intricate connection between plant inputs, microbial activity, and the soil matrix. This manifested how microorganisms, key players transforming plant-derived into carbon, are controlled physical arrangement of inorganic particles. Here we conduct incubation isotopically labelled litter to study effects structure on fate litter-derived matter. While activity fungal growth enhanced coarser-textured soil, show that occlusion matter aggregates formation organo-mineral associations occur concurrently fresh surfaces regardless structure. These two mechanisms—the most prominent processes contributing persistence matter—occur directly at plant–soil interfaces, where constitute a nucleus build-up persistence. We extend notion litter, i.e., particulate matter, from solely easily available labile substrate, functional component which determined.

Microplastic effects on carbon cycling processes in soils

PLoS Biology, Journal Year: 2021, Volume and Issue: 19(3), P. e3001130 - e3001130

Published: March 30, 2021

Microplastics (MPs), plastic particles <5 mm, are found in environments, including terrestrial ecosystems, planetwide. Most research so far has focused on ecotoxicology, examining effects performance of soil biota controlled settings. As pivots to a more ecosystem and global change perspective, questions about soil-borne biogeochemical cycles become important. MPs can affect the carbon cycle numerous ways, for example, by being themselves influencing microbial processes, plant growth, or litter decomposition. Great uncertainty surrounds nano-sized particles, an expected by-product further fragmentation MPs. A major concerted effort is required understand pervasive functioning soils ecosystems; importantly, such needs capture immense diversity these terms chemistry, aging, size, shape.

Microbial carbon use efficiency promotes global soil carbon storage

Biochar in agriculture – A systematic review of 26 global meta‐analyses

GCB Bioenergy, Journal Year: 2021, Volume and Issue: 13(11), P. 1708 - 1730

Published: Sept. 1, 2021

Abstract Biochar is obtained by pyrolyzing biomass and is, definition, applied in a way that avoids its rapid oxidation to CO 2 . Its use agriculture includes animal feeding, manure treatment (e.g. as additive for bedding, composting, storage or anaerobic digestion), fertilizer component direct soil application. Because the feedstock carbon photosynthetically fixed from atmosphere, producing applying biochar essentially dioxide removal (CDR) technology, which has high‐technology readiness level. However, swift implementation of pyrogenic capture (PyCCS), needs deliver co‐benefits, example, improving crop yields ecosystem services and/or climate change resilience ameliorating key properties. Agronomic research rapidly evolving field moving less than 100 publications 2010 more 15,000 end 2020. Here, we summarize 26 rigorously selected meta‐analyses published since 2016 investigated multitude properties agronomic performance parameters impacted application, effects on yield, root biomass, water efficiency, microbial activity, organic greenhouse gas emissions. All show compelling evidence overall beneficial effect all parameters. One remaining challenges standardization basic analysis, still lacking many studies. Incomplete characterization increases uncertainty because adverse individual studies included might be related low‐quality biochars, would not qualify certification subsequent high content contaminants, salinity, incomplete pyrolysis, etc.). In summary, our systematic review suggests potential combine CDR with significant environmental co‐benefits.

Contrasting pathways of carbon sequestration in paddy and upland soils

Global Change Biology, Journal Year: 2021, Volume and Issue: 27(11), P. 2478 - 2490

Published: March 13, 2021

Paddy soils make up the largest anthropogenic wetlands on earth, and are characterized by a prominent potential for organic carbon (C) sequestration. By quantifying plant- microbial-derived C in across four climate zones, we identified that accrual is achieved via contrasting pathways paddy upland soils. Paddies 39%-127% more efficient soil (SOC) sequestration than their adjacent counterparts, with greater differences warmer cooler climates. Upland replenished C, whereas enriched proportion of plant-derived because retarded microbial decomposition under anaerobic conditions induced flooding paddies. Under both land-use types, maximal contribution plant residues to SOC at intermediate mean annual temperature (15-20°C), neutral (pH~7.3), low clay/sand ratio. contrast, high (~24°C), pH (~5), large ratio favorable strengthening necromass. The necromass waterlogged paddies climates likely due fast anabolism from bacteria, fungi unlikely be involved as they aerobic. In scenario conversion upland, total 504 Tg may lost CO

A critical review of mineral–microbe interaction and co-evolution: mechanisms and applications

National Science Review, Journal Year: 2022, Volume and Issue: 9(10)

Published: July 4, 2022

Mineral–microbe interactions play important roles in environmental change, biogeochemical cycling of elements and formation ore deposits. Minerals provide both beneficial (physical chemical protection, nutrients, energy) detrimental (toxic substances oxidative pressure) effects to microbes, resulting mineral-specific microbial colonization. Microbes impact dissolution, transformation precipitation minerals through their activity, either genetically controlled or metabolism-induced biomineralization. Through these interactions, microbes co-evolve Earth history. typically occur at microscopic scale but the effect is often manifested global scale. Despite advances achieved decades research, major questions remain. Four areas are identified for future research: integrating mineral ecology, establishing biosignatures, linking laboratory mechanistic investigation field observation, manipulating mineral–microbe benefit humankind.
