Neco 2020 Agricultural Science Question 2
Practice objective / multiple choice question 2 from the 2020 Neco Agricultural Science examination.
A forest area of \(200\) ha is planted with species X at a spacing of \(3\) m \(\times\) \(3\) m. The volume growth of each tree is given by \(V = 0.05 t^{2}\) (m\(^3\)) where \(t\) is the age in years. The forest is managed on a \(30\)-year rotation.\n\n(a) Calculate the total timber volume (in m\(^3\)) that can be harvested at the end of the rotation.\n(b) Determine the average annual allowable cut (AAC) in m\(^3\) ha\(^{-1}\) yr\(^{-1}\).\n(c) If a \(10\)% loss occurs due to pests, what is the adjusted AAC?
