Practice objective / multiple choice question 12 from the 2018 Waec Model Questions Vol1 Geography examination.
A soil sample contains 45% sand, 35% silt and 20% clay by weight. The field capacity (FC) can be estimated by FC = 0.2 S + 0.3 C + 0.1 Si (where S, C and Si are the percentages of sand, clay and silt respectively). The wilting point (WP) is given by WP = 0.1 S + 0.2 C + 0.05 Si. Calculate the available water holding capacity (AWHC = FC - WP) in percent and state whether the soil is suitable for a crop that requires a minimum AWHC of 12%.
