Waec Model Questions Vol1 2021 Agricultural Science Question 22
Practice objective / multiple choice question 22 from the 2021 Waec Model Questions Vol1 Agricultural Science examination.
A 500‑hectare forest is managed on a 30‑year rotation. The average annual increment (AAI) of timber volume is 2.5 m³ ha⁻¹ yr⁻¹ for the first 20 years and then declines linearly to 1.0 m³ ha⁻¹ yr⁻¹ by the end of year 30. Assuming the initial standing volume is zero and that the same constant volume is harvested each year, what is the maximum sustainable annual harvest (in cubic metres) that will leave the standing stock at zero at the end of the rotation?
