Water content in soil is the ratio of water mass to the dry mass of soil expressed as a percentage, which is key for understanding soil's capacity to support plant life.
The water (or moisture) content of soil refers to the ratio of mass of water to dry mass of soil expressed as a percentage. It is a crucial parameter that determines how well soil can support plant growth, its texture, and its water holding capacity between field capacity and the permanent wilting point.
Different types of soils, such as sandy or clay soils, differ in their water content due to the size of their particles and pore spaces. Too much or too little water impacts plant health, with water potential energy being an important determinant of soil wetness and plant water uptake over simple water content measurements.
