Description:	The soils in the central Amazon are highly weathered and have low nutrient contents. Therefore, fertilization is essential for fruit tree production. Nitrogen may additionally be supplied by biological N fixation of a legume cover crop, which is often planted in tropical fruit tree plantations. However, the effectiveness of the atmospheric N from the legume for tree N nutrition, and the combined effects of fertilization and cover cropping on the soil N dynamics and nutrient uptake by the fruit tree has rarely been assessed in tropical cropping systems with perennial plants. Therefore, we studied the soil and plant N dynamics as affected by fertilization and intercropping with a legume.
