Neco Model Questions Vol1 2025 Agricultural Science Question 7
Practice objective / multiple choice question 7 from the 2025 Neco Model Questions Vol1 Agricultural Science examination.
A forest manager wants to determine the sustainable Annual Allowable Cut (AAC) from a \(100\) ha teak stand. The average tree height is \(20\) m and the average diameter at breast height (DBH) is \(30\) cm. Tree volume (in m\(^3\)) is approximated by \(V = 0.0005\,D^{2}\,H\), where \(D\) is in cm and \(H\) in metres. The stand density is \(500\) trees per ha. Annual volume growth is \(2.5\)% of the standing volume after harvest, and the manager requires that the standing volume after harvest and growth be at least \(80\)% of the initial volume. What is the maximum volume (in m\(^3\)) that can be harvested each year while meeting this condition?
