Bacterial metabolism rather than necromass dominates input to soil organic carbon

Annette Dathe, Laurel Lynch, Dominic Woolf, Johannes Lehmann

Soil organic carbon (OC) sequestration is presumed to rely to a large extent on microbial transformation of plant residues into microbial necromass. Necromass formation, however, represents only one pathway by which microorganisms contribute to soil organic matter, while OC released through metabolism …

Biochar Permanence—A Policy Commentary

Hans‐Peter Schmidt, Samuel Abiven, Annette Cowie, Bruno Glaser et autres

ABSTRACT The application of biochar to soil is a highly durable nature‐based carbon dioxide removal (CDR) pathway. It provides certifiable climate‐change mitigation, with mean carbon residence times exceeding 1,000 years, and additional co‐benefits for soil health and fertility. Biochar persistence in soil …

Managing for climate and production goals on crop-lands

Shelby C. McClelland, Déborah Bossio, Doria R. Gordon, Johannes Lehmann et autres

The assumption that crop-land natural climate solutions (NCS) have benefits for both climate change mitigation and crop production remains largely untested. Here we model GHG emissions and crop yields from crop-land NCS through the end of the century. We find that favourable …

Greenhouse gas mitigation on croplands: clarifying the debate on knowns, unknowns and risks to move forward with effective management interventions

Emily E. Oldfield, Jocelyn M. Lavallee, Jennifer Blesh, Mark A. Bradford et autres

The opportunity of agricultural management practices to sequester soil organic carbon (SOC) is recognized as an important strategy for mitigating climate change. However, there is low confidence when it comes to understanding the magnitude of the climate benefit we can expect from …

Importance of Terrain and Climate for Predicting Soil Organic Carbon Is Highly Variable across Local to Continental Scales

Tianhong Tan, Giulio Genova, G.B.M. Heuvelink, Johannes Lehmann et autres

Soil organic carbon (SOC) plays a vital role in global carbon cycling and sequestration, underpinning the need for a comprehensive understanding of its distribution and controls. This study explores the importance of various covariates on SOC spatial distribution at both local (up …

Persistence of biochar

Johannes Lehmann, Samuel Abiven, Elias Azzi, Yunying Fang et autres

Biochar persistence depends on both biochar properties and environmental conditions. This chapter discusses the mechanisms by which biochar is mineralized, and how it can be predicted. Mineralization of biochars can be related to either their production conditions or their properties. Pyrolyzing organic …

Biochar, greenhouse gas accounting, and climate change mitigation

Annette Cowie, Elias Azzi, Zhe Weng, Dominic Woolf

Biochar can provide climate change mitigation through carbon dioxide removal and emissions reduction. The most important mitigation process is C sequestration in persistent biochar. Other processes contributing to mitigation include: reduced non-CO 2 greenhouse gas (GHG) emissions from soil; stabilization of soil …

The fate of rice crop residues and context-dependent greenhouse gas emissions: Model-based insights from Eastern India

The fate of rice crop residues and context-dependent greenhouse gas emissions: Model-based insights from Eastern India

Emily Urban Cordeiro, Laura Arenas-Calle, Dominic Woolf, Sonam Sherpa et autres

Crop residue burning is a common practice in many parts of the world that causes air pollution and greenhouse gas (GHG) emissions. Regenerative practices that return residues to the soil offer a ‘no burn’ pathway for addressing air pollution while building soil …
