Description:	In this study we were mesuring mineral and total soil N to a depth of 8 m in secondary forest and under two primary forest species in three replicates, in Manaus-AM (Brasil). The results show low amounts of nitrate underneath the secondary forest to a depth of 2 m, whereas the nitrate contents under the two primary forest sites were high at 1 m - 2 m depth. Below 2 m depth, it was reversed and the mineral soil N was higher under the secondary forest than the primary forest. The N mineralization showed the same trend indicating that a large portion of the N is leached in its organic form.
