Carbon and nitrogen in the ground waters of the Tellerman forest (European southern forest steppe)

摘要

Under the upland forests growing on the Dnieper loamy soils at 150-160 m above sea level, sandy aquifers are found at similar to 120 and similar to 140 m above sea level. The general mineralization of groundwaters (GWs) and the concentration of SO (4) (-2) increase upon approaching the foundation of fluvial glacial sediments. The concentration of C supplied to the local GWs is 10-12 mg L-1 per year(-1). The concentration of C(CO (3) (-2) ; HCO (3) (-1) ; NO (3) (-1) ; NO (2) (-1) ) in the DSW is consistent with the C balance of upper biogeocenoses and the rate of groundwater migration. The concentrations of N(nh (4) (+1) ) are unrelated to the filtration of biogeocenosis moisture. They are identical both under sodic grassy glades and highly productive tree stands. The main part of N-containing ions in situ is synthesized and destroyed by anaerobic microorganisms living in the GW.
