Conteúdo: | Investigation of the root activity of different tree species (cupuacu, peach palm, Brazil nut, urucum, vismia) in an agroforestry system compared to a fallow vegetation. The results showed important indications for the suitability of peach palm and Brazil nut for the recycling of leached nutrients. In the highly permeable Ferralsols at the experimental site, a deeper root activity may also reduce nutrient leaching into the subsoil. It's observed higher amounts of nitrate in the subsoil under cupuacu than under any of the other trees species. This may indicate an advantage of deeper rooted trees for the reduction of leaching of fertilized nutrientes.
