摘要：

Although conifers usually seem able to obtain sufficient nitrogen for establishment, it was shown that 36 year‐old Corsican pine on infertile sands responded to application of ammonium sulphate at rates greater than 84 kg N/ha by greatly increased height growth and diameter growth. After canopy closure, increasing amounts of nitrogen became immobilised in the litter, so that nitrogen deficiency arose less from increased demand for nitrogen by the tree than from a decrease in the available supplies.
