Changes in net global warming potential (GWP) and greenhouse gas intensity (GHGI) due to no-till (NT) vs. conventional till (CT) with the duration of the experiment using the soil organic C method.

<p>Full accounting data denote calculations of GWP and GHGI by accounting all sources and sinks of CO₂ (N₂O and CH₄ emissions, farm operations, inputs, and soil C sequestration) and Partial accounting data, partial accounting of sources and sinks (N₂O and CH₄ emissions and/or soil C sequestration). All data denotes inclusions of full and partial accounting data.
