Lysimeter is a device used to measure the amount of water that passes through soil. It consists of a container filled with soil that is placed in the ground or isolated from the surrounding soil. The amount of water entering the container, typically from precipitation or irrigation, is measured. Similarly, the amount of water leaving the container, primarily through drainage and evapotranspiration, is also quantified. By comparing the input and output of water, scientists can determine the water balance of a particular soil profile. Lysimeters are valuable tools in hydrology, soil science, and agriculture for studying water movement, irrigation efficiency, and the impact of different land management practices on water resources. Different types of lysimeters exist, including drainage lysimeters, which collect percolating water, and weighing lysimeters, which measure changes in soil mass due to water content. They are often employed in experimental settings to gather precise data on water flux under controlled conditions.
