Radar diagrams of the average well colour development (AWCD) values for the eight main groups of the Biolog carbon compounds in the 0–20 cm (a) and 20–40 cm (b) soil layer of managed (continuous line) and abandoned orchard (dashed line). The means (𝑛=9) with the asterisk are significantly different between the two systems at 𝑃<0.01.
