Water content refers to the amount of water present in a substance, which can be expressed as a percentage of the total weight or volume. It is an important factor in various fields, including agriculture, food science, and environmental studies. For example, the water content in soil affects plant growth, while the water content in food influences its texture and shelf life. Measuring water content can be done using different methods, such as drying samples in an oven or using specialized instruments like moisture meters. Understanding water content helps in making informed decisions about irrigation, food preservation, and material storage.
