Table 3: Statistical parameters of soil organic matter associated with the various microenvironments.
For each position and for each depth, means within a column followed by different letters differ at p = 0.05. BS = bare soil, ERS and ORM = embedded and on-top small rock fragments (RFs), ERM and ORM = embedded and on-top medium RFs; ERL and ORM = embedded and on-top large RFs, CV = coefficient of variation.
