Dataset of net soil GHG emissions and yield for conservation tillage scenarios in northern U.S. spring canola systems

It underlies the analyses in the manuscript “Beyond one-size-fits-all: context-dependent conservation practice effects on net soil GHG emissions in northern U.S. spring canola” (submitted to <i>Earth's Future</i>).</p><p dir="ltr">The Excel file provides, for each site, region, and tillage scenario (e.g. conventional tillage, reduced tillage, no-till), annual net soil GHG emissions (area-based, in CO2-equivalent units) and productivity-normalized net soil GHG emission intensity (CO2-equivalents per unit yield), along with associated yield and auxiliary variables needed for the calculations.

Values are derived from process-based model simulations post-processed to match the experimental design described in the manuscript.</p><p dir="ltr">The dataset is intended to support replication of figures and tables related to tillage effects on net soil GHG emission intensity, and to enable reuse in meta-analyses or cross-system comparisons of conservation tillage impacts. Detailed information on model configuration, scenario setup, and unit conversions is provided in the Methods section of the associated manuscript.</p>
