Gce Model Questions Vol1 2023 Geography Question 11
Practice objective / multiple choice question 11 from the 2023 Gce Model Questions Vol1 Geography examination.
A farmer applies nitrogen fertilizer at a rate of \(F\) kg ha\(^{-1}\). The crop yield (ton ha\(^{-1}\)) before any adjustments is given by \(Y = 2 + 0.05F - 0.0001F^{2}\). A forecasted rainfall deficit will reduce the yield by \(0.02\) t for each percent of deficit; the expected deficit is 10 %. After the rainfall effect, pest damage reduces the remaining yield by 5 %. Determine the amount of nitrogen fertilizer \(F\) (kg ha\(^{-1}\)) that maximises the final yield after all adjustments.
