field soil water capacity from laboratory-measured soil
properties. World Congress of Soil Science. 182-185 Published on
DVD. Interpretive Summary: Field capacity (FC), defined as the
amount of water remaining in soil after the soil has been
saturated and then allowed to drain thoroughly, is a very
important soil hydraulic parameter that has multiple uses in
hydrological, meteorological, agronomical, and environmental
predictions and modeling. The customary way to estimate FC is to
utilize laboratory equipment that applies a specific pressure to
the soil and subsequently measure the water content. However,
there is no one standard pressure accepted world wide. As a
consequence, it is difficult to compare published FC values
generated in different countries for similar soil
