OBJECTIVE FORESTRY

Detailed explanation-1: -The rotation time of a forest stand is normally at least 100 years, as opposed to mere three years (on average) on a short rotation site. In agriculture, less than one year elapses between sowing and harvest.

Detailed explanation-2: -The biological rotation age represents the time of highest biological productivity and is reached when the average annual increase is equal to the current annual growth. The biological rotation age coincides with the age at which trees reached the maximum average basal area increment (Assmann, 1970).
