Neco 2022 Agricultural Science Question 16
Practice objective / multiple choice question 16 from the 2022 Neco Agricultural Science examination.
A forest stand covers 100 ha and initially has 80 trees per hectare. Each tree has an average DBH of 30 cm and an average height of 15 m. Tree volume (in m³) can be estimated by \( V = 0.0001 \times DBH^{2} \times H \). The DBH of each tree increases by 0.5 cm each year. Every 5 years a harvest removes a constant proportion \(p\) of the standing volume. Assuming the height remains constant, what is the greatest whole‑number percentage of the standing volume that can be harvested every 5 years so that after 20 years the total standing volume is not less than the initial volume? Give your answer as a percent rounded to the nearest whole number.
