Neco 2024 Agricultural Science Question 47
Practice objective / multiple choice question 47 from the 2024 Neco Agricultural Science examination.
Soil analysis shows an available phosphorus level of \(12\)\,mg\,kg^{-1}. The target level is \(30\)\,mg\,kg^{-1}. A fertilizer of single superphosphate contains \(18\%\) \(P_{2}O_{5}\) by weight. The soil bulk density is \(1.3\)\,g\,cm^{-3} and the plough layer depth is \(15\)\,cm. Assuming 100\% efficiency, calculate the amount of this fertilizer that must be applied per hectare (in kilograms) to raise the phosphorus level to the target.
