Gce Model Questions Vol1 2017 Agricultural Science Question 10
Practice objective / multiple choice question 10 from the 2017 Gce Model Questions Vol1 Agricultural Science examination.
A forest of species Z follows the volume growth function \(V(t)=12t-0.1t^{2}\) (m³ ha⁻¹) for ages \(0\le t\le60\) years. Each year the stand loses 2 % of its standing volume due to natural mortality (assumed to act continuously, i.e. the volume after \(t\) years is \(V(t)\times0.98^{t}\)). Timber sells for $150 per m³ and the discount rate is 6 % per annum (discrete). The manager wishes to choose a rotation age that maximises the present value of net timber revenue from a single rotation. Determine the optimal integer rotation age (in years).
