Neco Model Questions Vol1 2017 Geography Question 38
Practice objective / multiple choice question 38 from the 2017 Neco Model Questions Vol1 Geography examination.
Three soil samples have the following texture percentages (sand %, silt %, clay %). - Soil A: 40 % sand, 40 % silt, 20 % clay. - Soil B: 30 % sand, 50 % silt, 20 % clay. - Soil C: 20 % sand, 30 % silt, 50 % clay. A simplified field‑capacity (FC) model estimates FC (in mm) as \(FC = 0.2\times S + 0.1\times Si + 0.05\times C\), where \(S, Si, C\) are the sand, silt and clay percentages respectively. Which soil has the highest estimated field capacity and is therefore most suitable for agriculture?
