Figure 3

Mean relative difference (%) of marketable yields from 2003 to 2018 between alternative tillage and fertilisation treatments, with CT-SL set to 100%. Lines are drawn to facilitate readability. Biodynamic preparations were pooled. Crops include WW - winter wheat, SF – sunflower, SP – spelt, GC – grass-clover and SM – silage maize. SF* – yield loss in 2010. Significant differences between tillage (T) and fertilisation (F) treatments as well as interactions are indicated in capital letters (p < 0.05, (p) <0.1). Absolute yields and detailed ANOVA analysis are shown in Table S2 in the Supplement.
