Gce Model Questions Vol1 2024 Agricultural Science Question 16
Practice objective / multiple choice question 16 from the 2024 Gce Model Questions Vol1 Agricultural Science examination.
A farmer has 10 ha of land and plans a 3‑year crop sequence: Year 1 maize, Year 2 soybean (a legume), and Year 3 maize again. Maize yields 5 t ha⁻¹ and sells for $200 t⁻¹; it requires 80 kg N ha⁻¹ applied as fertilizer costing $0.5 kg⁻¹. Soybean yields 2.5 t ha⁻¹, sells for $350 t⁻¹ and fixes 30 kg N ha⁻¹, which reduces the nitrogen requirement of the subsequent maize crop. Fixed costs (land, machinery) are $12 000 per season. Should the farmer adopt the rotation or grow maize continuously for the three years, and by how much does the more profitable system increase profit?
