Gce Model Questions Vol1 2018 Geography Question 31
Practice objective / multiple choice question 31 from the 2018 Gce Model Questions Vol1 Geography examination.
A \(1\)‑ha field has a uniform soil depth of \(0.30\) m, a bulk density of \(1.4\) g cm\(^{-3}\), a field capacity of \(0.35\) cm\(^3\) cm\(^{-3}\) and a wilting point of \(0.15\) cm\(^3\) cm\(^{-3}\). The crop to be grown requires a total water use of \(500\) mm during the season. The seasonal rainfall forecast is \(300\) mm. Assuming the soil water stored between field capacity and wilting point can be fully utilised, calculate the volume of irrigation water (in cubic metres) that must be applied to meet the crop's water requirement.
