Neco Model Questions Vol1 2022 Geography Question 43
Practice objective / multiple choice question 43 from the 2022 Neco Model Questions Vol1 Geography examination.
A soil sample has a bulk density of \(1.3\ \text{g cm}^{-3}\) and a depth of \(15\ \text{cm}\) over an area of one hectare. Its buffer capacity is \(0.5\ \text{meq H}^{+}\ \text{kg}^{-1}\) per pH unit. The current pH is \(5.2\) and the desired pH is \(6.5\). Assuming calcium carbonate (\(\text{CaCO}_{3}\)) neutralises two moles of acidity per mole, calculate the amount of CaCO\(_3\) (in kilograms) required per hectare to raise the pH to the target level.
