Neco Model Questions Vol1 2024 Geography Question 9
Practice objective / multiple choice question 9 from the 2024 Neco Model Questions Vol1 Geography examination.
A soil profile has sand \(40\%\), silt \(35\%\) and clay \(25\%\) by weight, with a bulk density of \(1.4\) g cm\(^{-3}\). Its field capacity is \(0.30\) cm\(^3\) cm\(^{-3}\) and wilting point is \(0.15\) cm\(^3\) cm\(^{-3}\). Assuming a root‑zone depth of \(30\) cm, calculate the soil's available water holding capacity (AWC) in millimetres. A crop requires \(5\) mm of water per day for \(10\) days. Is the soil's AWC sufficient to meet the crop's water demand without irrigation? Show your work.
