Neco Model Questions Vol1 2019 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2019 Neco Model Questions Vol1 Agricultural Science examination.
A forest of 100 ha is planted with a fast‑growing species whose growth follows the logistic model \(\Delta S = r S\left(1-\frac{S}{K}\right)\) where \(S\) is the standing stock (m³/ha), \(r = 0.1\) yr⁻¹ and the carrying capacity \(K = 200\) m³/ha. The initial standing stock is 120 m³/ha. The manager wants to harvest a constant volume \(H\) each year while keeping the stock from falling below the initial level. Determine the maximum sustainable annual harvest \(H_{max}\) (in m³/ha·yr). If timber sells for ₦2,500 per m³ and the cost of harvesting is ₦300 per m³, calculate the net annual revenue per hectare from this sustainable harvest.
