Article Synopsis
  • Ecosystems act as both sources and sinks for atmospheric carbon (C), and their carbon use efficiency (CUE) is crucial for mitigating climate change.
  • Increased nitrogen (N) availability from human activities may lead to phosphorus (P) limitations in terrestrial ecosystems, affecting how plants and microorganisms utilize carbon.
  • In a Mediterranean tree-grass ecosystem study, it was found that wetter conditions and N fertilization improved CUE, but seasonal changes and potential longer dry summers could decrease CUE in the future.

Background: Achieving a net zero greenhouse gas United States (US) economy is likely to require both deep sectoral mitigation and additional carbon dioxide removals to offset hard-to-abate emissions. Enhancing the terrestrial carbon sink, through practices such as the adoption of no-till and cover cropping agricultural management, could provide a portion of these required offsets. Changing domestic agricultural practices to optimize carbon content, however, might reduce or shift US agricultural commodity outputs and exports, with potential implications on respective global markets and land use patterns.

Plant-soil feedbacks are an important aspect of invasive species success. One type of feedback is alteration of soil nutrient cycling. Cheatgrass invasion in the western USA is associated with increases in plant-available nitrogen (N), but the mechanism for this has not been elucidated.
