Nitrogen leaching after clear-cutting was studied with a process-based ecosystem model. Previous nitrogen fertilization did not increase nitrogen leaching. The model estimates indicated increased nitrogen leaching due to disc trenching. Water drainage and vegetation nitrogen uptake controlled nitrogen leaching.
