Neco 2023 Agricultural Science Question 46
Practice objective / multiple choice question 46 from the 2023 Neco Agricultural Science examination.
An area of \(10\) ha of fast‑growing timber is planted at a density of \(200\) trees per hectare. Each tree yields \(0.5\) m³ of timber at age \(5\) years and the volume per tree increases by a factor of \(1.2\) every subsequent \(5\)-year period. At age \(15\) years a thinning removes \(30\%\) of the trees, the removed trees are harvested immediately. The remaining trees are left to grow and are finally harvested at age \(30\) years. Calculate the total timber volume (in cubic metres, to two decimal places) that will be harvested from the whole \(10\) ha stand.
