Design of the experiment:

  • Randomized block design, originally with 12 treatments and four blocks.
  • Plots are 50 x 50 m.
  • In 2003, a fifth block of mature forest was added to serve as a reference.
  • In 2004, four transects in abandoned pasture were added, also for reference.

Study plot elevation, soil type, and location according to La Selva grid system
