The weight of the water contained in an object or material, usually expressed as a percentage of weight


In biology, the term moisture is associated with the presence of liquid, particularly water. The presence of the liquid though is not very great in amount but only up to a certain degree that renders something wet or damp.

Moisture content (or water content) refers to the weight of the water contained in a certain object or material. It is usually expressed as a percentage of weight. For instance, soil moisture pertains to the water content of the soil. Several methods may be used to determine in situ soil water content, e.g. ground penetrating radar, electrical resistivity tomography, neutron probe, time-domain reflectometry, etc.

Moisture content may be expressed as a ratio and may range from zero (0) to the value of the porosity o the material at saturation. Determining water content is applied in different scientific fields. One of them is in agriculture. Water content is an important factor in growing crops. A soil that is too dry leads to the drop in plant transpiration and might lead to a wilting point when the plant would no longer be able to extract water.
