Gce Model Questions Vol1 2022 Agricultural Science Question 48
Practice objective / multiple choice question 48 from the 2022 Gce Model Questions Vol1 Agricultural Science examination.
Soil tests on a 2 ha field show available nutrients: nitrogen 40 kg ha⁻¹, phosphorus 12 kg ha⁻¹ (as P), potassium 30 kg ha⁻¹ (as K). For optimal maize yield the target levels are 120 kg ha⁻¹ N, 60 kg ha⁻¹ P₂O₅, and 80 kg ha⁻¹ K₂O. Fertiliser sources are: urea (46 % N), single superphosphate (20 % P₂O₅), and muriate of potash (60 % K₂O). (i) Calculate the amount of each fertiliser (kg ha⁻¹) required to meet the targets exactly. (ii) If the costs are ₦30 kg⁻¹ for urea, ₦25 kg⁻¹ for SSP and ₦20 kg⁻¹ for MOP, compute the total fertiliser cost per hectare (nearest naira).
