Wechselseitige Effekte von Regenwürmern und Klimawandel auf die Dynamik und Speicherung von organischem Kohlenstoff im Boden
Zusammenfassung der Projektergebnisse
Our results confirm that earthworms foster the formation of microbial-derived, mineral-associated organic matter. We document this, for the first time, visually and on the micro level. Surprising to us was that these effects were hardly affected by land use or simulated future climates, perhaps, indicating that the effects of earthworms on mineral-associated organic matter are consistent under various environmental conditions. We further found potentially strong effects of other soil faunal groups on the formation of particulate and mineral-associated organic matter. However, knowledge on this, both mechanistically and quantitatively, is virtually absent. We thus aim to expand our research beyond earthworms and quantitatively investigate the mechanisms by which individual faunal taxa (such as springtails or nematodes) and more complex faunal communities affect soil organic matter stabilization. We encourage cross-disciplinary studies on this nexus on various scales that employ physical fractionation, isotopic, and other molecular methods to close the major remaining research gaps to eventually apply the gained knowledge for improving modelling of soil carbon dynamics and carbon-focused soil management strategies.
