Question

Which soil among the following would you expect to have the highest percolation rate?

• A. Loamy
• B. Clayey
• C. Sandy
• D. Black

Answer 1

The correct option is C

Sandy

Percolation is the movement of water through soil, and the percolation rate is the speed at which that movement occurs.

1. Sand particles are quite large so, there are large spaces between them. Water passes easily through these spaces between the soil particles. Hence, percolation rate is highest for sandy soils.
2. Clayey soils have the lowest particle size so, there are less spaces between them. Hence, clayey soil has lowest percolation rate.
3. Loamy soils have particle size in between those of sandy and clayey soils. So, it has spaces between those of sandy and clayey soil. Hence, it has percolation rate between those of sandy and clayey soil.
