| Dendrocalamus asper, known as giant bamboo or bamboo-bucket, has been used as a substitute for wood and fiber, due mainly to its wide availability, rapid growth rate, short cycle and traditional use as construction material. In general, its cultivation is carried out on phosphorus-deficient soils, using vegetative propagation, mainly from cuttings. Thus, the aim of this study was to evaluate the effect of fertilization with phosphorus doses on the biomass allocation in roots, leaves and stems and on the level and content of P in leaves and roots of bamboo cuttings. The experiment was conducted in a greenhouse, using soil with low P content (2.4 mg dm-3). The treatments consisted of six doses of phosphorus (0, 20, 40, 80, 160 e 320 kg ha-1 of P2O5). The... |

| Soils with high acidity and low exchangeable bases may be responsible for low yields of Pinus taeda in a forest plantation at Jaguariaíva, Paraná State, Brazil. The aim of this study was to evaluate the effect of liming and fertilisation, applied over litter, on two selected areas with Pinus taeda plantations. Soil, litter and pine needles were evaluated for K, Ca and Mg concentrations and soil acidity parameters. Seven treatments were applied: (i) complete (N, P, K, Zn, Cu, B, Mo, and lime); (ii) without N, P, and K; (iii) without Zn, Cu, B, and Mo; (iv) without K; (v) without Zn; (vi) without lime; and (vii) control (without nutrients and lime). Soil samples were collected at five soil depths (0-5, 5-10, 10-20, 20-40 and 40-60 cm) simultaneously with... |
