A soil percolation test is a test to determine the rate of water seepage through a given soil. It is used to measure the permeability of soils. The test is performed by filling a metal cylinder with soil to a specific height and then pouring water into the top until the soil is saturated. The time it takes for all of the water to drain from the cylinder is recorded. The lower the time, the better the permeability of the soil.

A percolation test is a soil test that is used to determine the rate at which water will seep through a given soil. This information can be used to help determine the best way to irrigate or drain a particular area of land. The test is performed by digging a hole in the ground and then filling it with water. The time it takes for the water to seep from the hole is then measured.
