Variations of amino sugar concentrations in different soils. Pearson correlation with clay contents (a) and aridity index (b) in the Mongolian (n = 38) and non-Mongolian grassland soils (n = 38). SOC, soil organic carbon. Error bars represent s.e.m. for three site replicates in the Mongolian grasslands. Data for non-Mongolian soils are derived from the literature14,20,24,25, which uses a different clay measurement method from the Mongolian soils
