Which soil among the following would you expect to have the lowest percolation rate?
Clayey
Larger the particle size, easier it is for water to trickle into soil.
Thus, percolation rate is highest for sandy soils.
Clayey soils have the lowest particle size and hence, the lowest percolation rate.
Loamy soils, as usual, have percolation rates in between those of sandy and clayey soils.
