Meta-analysis based on the microbial target variables dataset to asses farming system induced effects on SOC (SOC), total nitrogen (TN) and pH chemistry.
The effect of organic and conventional managed systems on SOC, TN and pH was analysed by a random effects model with a 95% confidence interval (CI) and a Z-distribution. RR>1 indicates enhanced values
