Postulated change in the scale- and intersperse-dependent yield gap. Data evaluated by [4] on the organic-conventional yield gap focused on plot- to farm-scale comparisons, disregarding possible benefits from conventionally managed surrounding areas. For specific crops and conditions, the yield gap may approach zero, but it is 20% on average. With implementation of organic farming as the major farming system at larger scales, the dispersion of organic farms (green) in a conventional (brown) matrix is reversed to the opposite situation (square grids). Nutrient spillover and possible pest regulation effects get smaller, presumably making organic farming yields prone to hitherto undetected yield drops and higher variability.
