Moisture Content: 1.The amount of water lost from soil upon drying to a constant weight, expressed as the weight per unit of dry soil or as the volume of water per unit bulk volume of the soil.
soil moisture content The portion of water in a soil that can be readily absorbed by plant roots. It is the amount of water released between in situ field capacity and the permanent wilting point.
Moisture content
The proportion of water in a sample of biomass, defined as the weight of water as a percentage of the weight of biomass.
The moisture content of a soil at which plants (specifically sunflower plants) wilt and fail to recover their turgidity when placed in a dark, humid atmosphere. The wilting point is commonly estimated by measuring the 15-bar percentage of a soil.
the moisture content of freshly quarried stone, esp. if porous.
quicksilver water
a solution of mercury nitrate used in gilding.
Humidity - The moisture content of air. Relative humidity is the ratio of the amount of water vapor actually present in the air to the greatest amount possible at that temperature (the saturation vapor pressure).
Air mass:a large quantity of air throughout which temperature and moisture content is fairly constant. Air pressure:pressure exerted by the weight of air over a given area of Earth's surface.
The rate of infiltration changes dramatically as soil moisture content changes.
The zone between land surface and the water table within which the moisture content is less than saturation (except in the capillary fringe) and pressure is less than atmospheric. Soil pore space also typically contains air or other gases.
Dehumidification: The process of reducing the moisture content to a regulated work area.
Roughness of terrain, moisture content, solar angle, and angular and spectral distribution of ground- level irradiations are other factors affecting surface albedo. surface water All water naturally open to the atmosphere.
