An infiltrometer is a device used to measure the rate of water infiltration into soil. Tillage is an important factor that affects water infiltration into soil.
Our infiltrometer has a single ring. The ring is driven into the soil and then water is supplied to achieve a constant head. Water is held at a constant depth through use of a water reservoir and a float valve inside the infiltrometer. Infiltration is determined by measuring the quantity of water that infiltrates into the soil during a two hour period and/or when infiltration reaches a steady state.
