.... Total REE concentrations (ΣREE) recorded moderate seasonal variation, ranging from 31.0 mg kg −1 to 88.2 mg kg −1 , with an average of 53.5 mg kg −1 , similar to the ΣREE of local topsoil. The values of ΣREE were negatively correlated with the corresponding dust deposition fluxes, which may be due...

... surface N 2 O flux is dependent on the soil’s D p / D o , and WFPS alone does not suffice to discriminate between N 2 O emission sources. Consequently, the soil surface N 2 O flux may be comprised of N 2 O originating from deeper soil layers transported upward and/or from production in the topsoil...
