Mean relative differences (%) between alternative treatments to the standard treatment CT-SL (=100%) in the 0–10 cm soil layer of (a) soil biochemical indicators sampled in 2018 including pH, soil organic carbon (SOC), microbial biomass C and N (Cmic, Nmic), dehydrogenase activity (DHA) and plant available nutrients (P, K) (data pooled across biodynamic preparations, n = 8) and (b) soil biological indicators published in *Kuntz, et al.22 including total earthworm abundance and microbial groups determined by phospholipid fatty acid (PLFA) analysis (n = 4), **Säle, et al.23 including arbuscular mycorrhizal fungi (AMF) spore density (n = 4) and ***Krauss, et al.24 including rRNA data (nitrification and denitrification functional genes) (n = 3). Absolute results and detailed ANOVA analysis for 2a) are shown in Table S1 in the Supplement. Please note the different scales in (a,b).
