Soil moisture content is the quantity of water contained per
unit (volume or weight) of soil at any given time and is
often expressed as a percentage of the dry soil. It is also
common to indicate the moisture content in terms of mm of
water per meter of soil (mm/m). A relationship between these
two measurement terms can be established, but requires
information on the bulk density of the soil.
2M 2.8.112 Soil moisture potential Soil moisture potential refers to the potential energy of soil water with respect to free water. Although the total soil moisture potential has three components, i.e. the gravitational, osmotic and capillary or matric potential, it is often referred to the last one only, especially with regard to its relative importance.
