The British pint is about 20% larger than the American pint since the two systems are not compatible. Almost all other countries have standardized on the metric system, so the size of what may be called a pint varies depending on local custom.
It is usually measured by the depth (in mm) of the water layer that can enter the soil in one hour. An infiltration rate of 15 mm/hour means that a water layer of 15 mm on the soil surface, will take one hour to infiltrate. In dry soil, water infiltrates rapidly.
[The moisture content of the soil will affect the rate of infiltration; therefore, twoinfiltration tests are usually performed (if soil is dry). The first inch of water wets thesoil, and the second inch gives a better estimate of the infiltration rate of the soil.irm Soil With the 6-inch diameter ring in place, use your finger to gently firm the soil surface only around the inside edges of the ring to prevent extra seepage. Minimize disturbance to therest of the soil surface inside the ring.
