Mixed plantations might contribute to sustainable land use because of complementary nutrient use. Our objective was to assess the nutrient economy of five native tree species and their response to different neighbor trees in an experimental plantation in Panama. In our study, H. crepitans was the least nutrient efficient tree species. H. crepitans produced less biomass in mixtures than in monocultures while Cedrela odorata - the most nutrient efficient species - produced more biomass independent of stem growth rates because they acquired more nutrients in mixtures than in monocultures.Three-species mixtures had increased mean Ca concentrations in branches and stems and increased N, P, K, Ca, and Mg storage in aboveground biomass compared to monocultures suggesting complementary resource uptake. Our results highlight the need to properly consider species-specific nutrient requirements and species interactions when designing tree mixtures for afforestation.
