Data from: Field-scale experiments reveal persistent yield gaps in low-input and organic cropping systems

Alexandra N. Kravchenko, Sieglinde S. Snapp & G. Philip Robertson
Knowledge of production-system performance is largely based on observations at the experimental plot scale. Although yield gaps between plot-scale and field-scale research are widely acknowledged, their extent and persistence have not been experimentally examined in a systematic manner. At a site in southwest Michigan, we conducted a 6-y experiment to test the accuracy with which plot-scale crop-yield results can inform field-scale conclusions. We compared conventional versus alternative, that is, reduced-input and biologically based–organic, management practices...
