Waec Model Questions Vol1 2023 Agricultural Science Question 33
Practice objective / multiple choice question 33 from the 2023 Waec Model Questions Vol1 Agricultural Science examination.
A forest stand of a fast‑growing species follows the volume‑age relationship V(t) = 0.8 t² (m³ ha⁻¹), where t is the age in years (0 ≤ t ≤ 30). The stand is harvested at a uniform rotation age H, after which the area is immediately replanted. The net revenue per hectare from a harvest is 200 ₦ per m³ of timber minus a fixed replanting cost of 5 000 ₦. A discount rate of 8 % per annum applies. Using the Faustmann formula, determine the rotation age H (in whole years) that maximizes the land expectation value (LEV).
