Gce Model Questions Vol1 2019 Agricultural Science Question 31
Practice objective / multiple choice question 31 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A forest stand of a fast‑growing species follows the logistic growth model \( V(t)=\frac{K}{1+ae^{-bt}} \) where \(K=2000\) m³ ha⁻¹. At planting (\(t=0\)) the stand volume is 200 m³ ha⁻¹ and after 10 years it is measured at 800 m³ ha⁻¹. The stand is harvested every 5 years, each harvest removing a constant volume \(H\) (m³ ha⁻¹). To ensure the stand never falls below 300 m³ ha⁻¹, what is the greatest integer value of \(H\) that can be harvested each time over a 20‑year period?
