Neco Model Questions Vol1 2022 Agricultural Science Question 37
Practice objective / multiple choice question 37 from the 2022 Neco Model Questions Vol1 Agricultural Science examination.
In a managed forest, each hectare initially contains 200 mature trees. The volume (in m³) of a tree of age \(t\) years is given by \(V(t)=0.02t^{2}\). Trees are harvested when they reach 30 years. The manager wishes to supply 1 200 m³ of timber to the market each year. However, 15 % of the harvested timber must be retained for seedling production and cannot be sold. Assuming the forest area is 100 ha and that the same rotation is repeated continuously, calculate the minimum number of hectares that must be harvested each year to meet the market demand. Express your answer to the nearest whole hectare.
