Effects of long-term fertilization and cropping regimes on total nitrogen and organic nitrogen forms in a Mollisol of Northeast China

Effects of long-term fertilization and cropping regimes on total nitrogen and organic nitrogen forms in a Mollisol of Northeast China

A 22-year (1990-2012) field experiment was conducted to assess the effects of different fertilization and cropping regimes on the quantitative changes of total N and organic N forms in the topsoil (0-20 cm) and subsoil(20-40 cm) of a Mollisol in Northeast China.
