Appendix A. Model output demonstrating that crop production system was not a significant predictor of denitrification potential in the Logården samples and including this term did not affect other terms in the model.

Table A1. Coefficients for the model including a term indicating the crop production system at each sampling location. Farming system was not a significant predictor of PDA, while standardized effect sizes are similar to the modelAaveraged estimates in Fig. 1.
