Stem injection of (15)N-labeled ammonium sulfate was used to determine effects of pruning on canopy nitrogen dynamics in open-grown Pinus radiata D. Don in New Zealand. Trees were planted in July 1990 and the isotope introduced in December 1994. Tree crowns were divided into three zones: base section, from which branches of pruned trees were removed; mid section, between the pruned zone and the height of the trees at the start of the year in which they were pruned; and top section, which grew… CONTINUE READING
