Towards a global-scale soil climate mitigation strategy

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Oct. 27, 2020

Abstract Sustainable soil carbon sequestration practices need to be rapidly scaled up and implemented contribute climate change mitigation. We highlight that the major potential for is in cropland soils, especially those with large yield gaps and/or historic organic losses. The implementation of measures requires a diverse set options, each adapted local conditions management opportunities, accounting site-specific trade-offs. propose establishment information system containing localised on group, degradation status, crop gap, associated carbon-sequestration potentials, as well provision incentives policies translate options into region- soil-specific practices.

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.

Deconstructing the microbial necromass continuum to inform soil carbon sequestration

Functional Ecology, Journal Year: 2022, Volume and Issue: 36(6), P. 1396 - 1410

Published: Feb. 3, 2022

Abstract Microbial necromass is a large, dynamic and persistent component of soil organic carbon, the dominant terrestrial carbon pool. Quantification stocks its susceptibility to global change becoming standard practice in research. However, typical proxies used for do not reveal nature flows transformations within that ultimately determine persistence. In this review, we define deconstruct four stages continuum: production, recycling, stabilization destabilization. Current understanding dynamics described each continuum stage. We highlight recent advances, methodological limitations knowledge gaps which need be addressed pool sizes transformations. discuss controls on process rates aspects microscale structure including biofilms food web interactions. The relative importance stage then compared contrasting ecosystems climate drivers. From perspective continuum, draw three conclusions inform future First, persistence are more clearly defined when viewed through lens continuum; second, destabilization least understood with recycling also poorly evidenced outside few ecosystems; third, response unresolved most ecosystems. Future mechanistic research focused role biotic abiotic determining organo–mineral organo–organo interactions can different scenarios.

Plant–soil synchrony in nutrient cycles: Learning from ecosystems to design sustainable agrosystems

Global Change Biology, Journal Year: 2023, Volume and Issue: 30(1)

Abstract Redesigning agrosystems to include more ecological regulations can help feed a growing human population, preserve soils for future productivity, limit dependency on synthetic fertilizers, and reduce agriculture contribution global changes such as eutrophication warming. However, guidelines redesigning cropping systems from natural make them sustainable remain limited. Synthetizing the knowledge biogeochemical cycles in ecosystems, we outline four that synchronize supply of soluble nutrients by soil biota with fluctuating nutrient demand plants. This synchrony limits deficiencies excesses nutrients, which usually penalize both production regulating services retention carbon storage.

Earthworms as catalysts in the formation and stabilization of soil microbial necromass

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(16), P. 4775 - 4782

Published: May 11, 2022

Microbial necromass is a central component of soil organic matter (SOM), whose management may be essential in mitigating atmospheric CO2 concentrations and climate change. Current consensus regards the magnitude microbial production to heavily dependent on carbon use efficiency microorganisms, which strongly influenced by quality inputs these organisms feed on. However, recent concepts neglect agents relevant many soils: earthworms. We argue that activity earthworms accelerates formation stabilized aggregates organo-mineral associations reduces relevance pre-existing this process. Earthworms achieve through creation transient hotspots (casts) characterized elevated contents bioavailable substrate efficient build-up quick turnover biomass, thus converting SOM not mineralized process into state more resistant against external disturbances, such as Promoting abundance may, therefore, considered strategies aim accelerate wide locations commonly formation.
