Study carried out on a highly weathered and aggregated Xanthic Ferralsol with a low cation exchange capacity on the gerra firme near Manaus-AM (Brasil) to investigate the nitrogen dynamics and the fate of applied nitrogen fertilizer in the soil-plnat system of a mixed cropping system consisting of Bactris gasipaes Kunth. (peachpalm, arecaceae), Theobroma grandiflorum (Willd. ex Spreng.) K. Schu. (cupuacu, Sterculiaceae), Bertholletia excelsa Humb. & Bpnpl. (Brazil nut, Lecythidaceae) and Bixa orellana L. (annato, Bixaceae). Annato, cupuacu and peachpalm seemed to take up more than 90% of the incorporated nitrogen fertilizer under their oyn canopy. However, Brazil nut took up more than 70% of the fertilized nitrogen from the fertilized areas under the canopies of the neighboring trees (peachpalm: 40%, annato: 36%, cupuacu: 6%). Furthermore, peachpalm and Brazil nut were better able than the other two trees in reducing nutrient leaching due to their deep root system. They took up nitrogen from the subsoil nitrogen pool, which was found under all investigated species as a result of leached fertilizer. |
