Effects of multi-storied plantation on nitrogen and carbon cycle

We aimed to elucidate effects of the multiple-storied plantation management on nitrogen (N) dynamics based on comparing N mineralization and budgets in multiple-storied stand of Cryptomeria japonica and Thujopsis dolabrata var. hondai with those in simple-storied stand of Cryptomeria japonica. There was no significant difference in mineralized N amounts. On the other hand, N leaching remarkably decreased not only in surface horizon but also in subsurface horizon of multiple-storied stand. This suggested that saplings of Thujopsis dolabrata var. hondai contributed to minimizing N leaching.
