In order to clarify the effect of mixed planting in the dynamics of phosporus (P), we assessed the fractions of this element in mixed plantings of Eucalyptus urophylla × E. grandis (Urograndis) and Acacia mangium in a tropical soil clay, analysing changes in the fractions of P and examining the correlation of these changes with the fractions of soil organic matter. Pure stands of Urograndis (E) and A. mangium (A) (0A:100E and 100A:0E) and mixed stands of the two species (50A:50E and 37A:66E) were established. The fractionation of P, the granulometric fractionation of organic matter and the labile carbon (POXC) were determined at soil depths of 0-5 and 5-10 cm. Regarding the availability of P, organic parts contributed 34.6% to 38.1% relative to the total P, with the highest percentages being observed for the moderately labile fraction. Highest levels of labile organic P were observed in the mixed plantations. About soil carbon (C), the highest levels of the more labile C fractions were recorded in plantations in which Acacia was present. Mixed plantations were found to show a greater balance between labile P and C fractions. The C fractions warrant particular attention in future studies, notably those related to the emission of greenhouse gases. |
