This refers to how quickly water can pass through a material. Different materials have different percolation rates. 3. **Percolation Rate of Soil**: Soil has a high percolation rate. This means that it has many small spaces or pores that allow water to be absorbed quickly. The presence of these pores in the soil enables it to hold water. ...
