Practice objective / multiple choice question 25 from the 2023 Waec Model Questions Vol1 Geography examination.
A field has a soil depth of 0.6 m and a bulk density of 1.4 g cm⁻³. The field capacity water content by weight is 0.30 and the wilting point is 0.15. A crop requires 5 mm of water per day for 20 days. The field receives a uniform rainfall of 30 mm during this period. Assuming the soil is initially at field capacity and that 10 % of any irrigation water applied is lost by percolation, calculate the total volume of water (in cubic metres) that must be supplied by irrigation for a 1‑hectare field. Round your answer to the nearest whole cubic metre.
