Neco 2025 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2025 Neco Agricultural Science examination.
A forest stand follows the logistic growth model \(V(t)=\frac{K}{1 + a e^{-b t}}\) with carrying capacity \(K = 300\) m³ ha⁻¹ and growth rate constant \(b = 0.08\) yr⁻¹. At present (t = 0) the stand volume is 120 m³ ha⁻¹. A manager wishes to harvest a fixed proportion \(p\) of the standing volume every 5 years, immediately after the growth period, while ensuring the post‑harvest volume never falls below 80 m³ ha⁻¹. Find the greatest integer value of \(p\) (as a percent) that can be sustained indefinitely.
