摘　　要：Dear Editor, Phosphorus (P) deficiency is the most limiting factor in tropical agriculture since most soils in this region are predominantly acids with high-energy P-binding compounds. Therefore, up to 90% of the P applied becomes fixed in soils, which raises environmental concerns and production costs (Syers et al., 2008). Thus, developing strategies to imptove P use efficiency (PUE) is essential to mitigate environmental problems and improve profits. These strategies should consider the soil-root-rhizosphere system because it is the most biochemical active site where nutrient uptake occurs (Hinsinger, 2011).
