  • ↵z Trees planted in August 2000; the experiment concluded in January 2001. Means are from 6 replications, standard error in parentheses.

  • ↵y Means in the table followed by the same letter are not significantly different (P < 0.05), LSD = 0.4.

  • Mean foliage P in unamended sand = 2.8 mg g−1.
