Abstract The reversibility of induced N saturation was investigated in a 46‐yr‐old pine ( Pinus sylvestris L.) forest in northern Sweden. Ammonium nitrate has been applied annually since 1971 to plots (30 by 30 m) at average dosages of 36 (N1), 72 (N2), and 108 (N3) kg N ha −1 yr −1 , with or withou...
