Neco 2021 Agricultural Science Question 23
Practice objective / multiple choice question 23 from the 2021 Neco Agricultural Science examination.
A teak plantation covers \(120\) ha. The average annual volume growth is \(8\) m³ per ha. The forest currently has a standing volume of \(10,000\) m³. The manager intends to harvest the same amount of timber each year for ten years, but the harvest in any year must not exceed \(10\%\) of the standing volume at the start of that year. After ten years the standing volume must be at least \(9,000\) m³. (i) Determine the maximum constant annual harvest volume (in m³) that satisfies both conditions. (ii) Assuming each cubic metre of teak stores \(0.9\) tonnes of CO₂, calculate the total amount of carbon sequestered in the standing volume after ten years.
