Gce Model Questions Vol1 2018 Geography Question 29
Practice objective / multiple choice question 29 from the 2018 Gce Model Questions Vol1 Geography examination.
A farmer intends to grow wheat on \(120\) ha. The expected yield without fertilizer is \(2.8\) t ha⁻¹. Applying nitrogen fertilizer increases yield according to \(\Delta Y = 3\,\ln(N+1)\) where \(N\) is the amount of nitrogen applied in tonnes per hectare. Nitrogen costs £450 per tonne and wheat sells for £170 per tonne. The farmer can adopt a precision‑application technology that reduces the nitrogen required by \(22\%\) but costs a fixed £12 000 for the whole farm. Determine the optimal amount of nitrogen per hectare (to two decimal places) that maximises the farmer's net profit, and state whether the precision technology should be adopted.
