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

This dataset contains site- and region-level summaries of net soil greenhouse gas (GHG) emissions and yield for contrasting tillage practices 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>Global Change Biology</i>).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.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.
