Under the strong leaching conditions of the humid tropics, soluble organic nutrient forms may be even more mobile and thus contribute to nutrients losses. We tested this phypothesis in soil under species of agroforestry systems (cupuacu, pupunha, pueraria) of a secondary (Vismia sp) and a of primary forest (bacaba, Eschweilera sp). The results show that dissolved organic matter contained a predominate proportion of nutrients in throughfall stemflow and soil solutions of agroforestry systems and forests of central Amazon. Organic nutrient forms contribute especially to the leaching of N into the subsoil. |
