Potential capacity and kinetic nitrat nitrogen migration of grey forest soil and fertilizer during time and its soil profile in Transbaikalia forest steppe

The potential capacity and kinetic of migration speed of soil source of nitrogen, nitrogen fertilizer and additional nitrogen interaction during vegetation season in grey soil profile was estimation for the first time. It was resulted for ecological soil conditions in Transbaikalia on the basis of microfield experements with labelled nitrogen -15 and components modelling.
