<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Why does sandy soil have a higher percolation rate than clayey soil?

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Sandy soil contains larger pores than clayey soil because sandy soil has coarse particles in greater proportion, while clayey soil has fine particles in greater proportion. Water can pass through larger pores faster, hence sandy soil has a higher percolation rate than clayey soil.
