Some results are as follows:
Pinus taeda plantation:
Age: 18 years
Spacing: 3 x 2 m
Mean annual volume increment: 15,5 m3 /ha.
Rotation of thinning: 3- 5yearsare suitable. Intensity: slight.
Alnus subcordata plantation:
Age: 9 years
Spacing: 2.5 x 2.5 , 3 x 3m
Mean annual volume increment: 18- 20 m3 / ha
Rotalion of thinning: 4 - 5years
Suitable thinning intensity: slight
