Gce Model Questions Vol1 2025 Agricultural Science Question 27
Practice objective / multiple choice question 27 from the 2025 Gce Model Questions Vol1 Agricultural Science examination.
A soil test shows that the topsoil contains \(0.12\%\) nitrogen (N), \(0.08\%\) phosphorus (P) and \(0.15\%\) potassium (K) by weight. The farmer wants to raise the nitrogen level to \(0.20\%\) while keeping phosphorus and potassium unchanged. The chosen fertilizer is a commercial NPK 20‑10‑10 (percent by weight). Assuming the topsoil mass is \(2{,}000{,}000\) kg per hectare, calculate how many kilograms of this fertilizer should be applied per hectare to meet the nitrogen target.
