dc.descriptionSoils of the humid tropics are known to be poor in nutrients and agricultural activities over a long period of time is only possible with the use of fertilizers. Because of the high amount of rainfall nutrient leaching losses are a major concern for nutrient management in the central Amazon (CAHN et al., 1993) and in general in humid tropical agro-ecosystems. Mixed cropping systems of trees with different root activity patterns may be able to use applied nutrients more efficiently and reduce unproductive losses through nutrient leaching (SCHROTH et al., 2000). The extent of nutrient competition and complementarity of nutrientuptake in multi-strata agroforestry systems is not entirely clear. Therefore, we studied the uptake of 15N-Iabelled fertilizer applied to four different tree crops in a mixed cropping system of the central Amazon.
