             abstract = "The productivity of rainforests growing on highly weathered 
                         tropical soils is expected to be limited by phosphorus 
                         availability(1). Yet, controlled fertilization experiments have 
                         been unable to demonstrate a dominant role for phosphorus in 
                         controlling tropical forest net primary productivity. Recent 
                         syntheses have demonstrated that responses to nitrogen addition 
                         are as large as to phosphorus(2), and adaptations to low 
                         phosphorus availability appear to enable net primary productivity 
                         to be maintained across major soil phosphorus gradients'. Thus, 
                         the extent to which phosphorus availability limits tropical forest 
                         productivity is highly uncertain. The majority of the Amazonia, 
                         however, is characterized by soils that are more depleted in 
                         phosphorus than those in which most tropical fertilization 
                         experiments have taken place(2). Thus, we established a 
                         phosphorus, nitrogen and base cation addition experiment in an old 
                         growth Amazon rainforest, with a low soil phosphorus content that 
                         is representative of approximately 60% of the Amazon basin. Here 
                         we show that net primary productivity increased exclusively with 
                         phosphorus addition. After 2 years, strong responses were observed 
                         in fine root (+29%) and canopy productivity (+19%), but not stem 
                         growth. The direct evidence of phosphorus limitation of net 
                         primary productivity suggests that phosphorus availability may 
                         restrict Amazon forest responses to CO2 fertilization(4), with 
                         major implications for future carbon sequestration and forest 
                         resilience to climate change.",
