Neco Model Questions Vol1 2023 Agricultural Science Question 2
Practice objective / multiple choice question 2 from the 2023 Neco Model Questions Vol1 Agricultural Science examination.
A soil test shows that a hectare of land contains 45 kg of nitrogen (N), 20 kg of phosphorus as P₂O₅ and 30 kg of potassium as K₂O. For a maize crop the target nutrient levels are 120 kg N, 60 kg P₂O₅ and 80 kg K₂O per hectare. Fertiliser A contains 30 % N, 20 % P₂O₅ and 10 % K₂O, while fertiliser B contains 15 % N, 30 % P₂O₅ and 20 % K₂O. Determine the least total amount (in kg) of fertilisers A and B that must be applied per hectare to meet or exceed each nutrient target. Then calculate the total cost if fertiliser A costs ₦12,000 per tonne and fertiliser B costs ₦10,000 per tonne. Give the cost rounded to the nearest hundred naira.
