Question

In field capacity, the soil contains

• A. Capillary and gravitational water
• B. Capillary and runaway water
• C. Hygroscopic and capillary water
• D. Hygroscopic, capillary and bound water

Answer 1

The correct option is D Hygroscopic, capillary and bound water

Field water capacity is defined by the Soil Science Glossary Terms Committee (2008) as the content of water, on a mass or volume basis, remaining in a soil 2 or 3 days after having been wetted with water and after free drainage is negligible. Gravitational water would reach the water table deep down and runaway water flows on the surface, hence not being available in the soil.
