Infiltrometers are used to measure what?

Explanation:
An infiltrometer measures how quickly water enters the soil—the infiltration rate. By tracking how fast water moves from the surface into the ground (often using a ring setup to minimize sideways flow), you get the rate of infiltration per unit area. This helps assess drainage, irrigation effectiveness, and potential runoff. The other options aren’t about water entering soil: water hardness is about minerals in water, sediment size is about particle sizes, and air humidity measures moisture in the air.
