A field lysimeter or simply lysimeter (from Greek λύσις (loosening) and the suffix -meter) is a container filled with soil, typically of cylindrical shape, which can be used to study the transport of water and material through the soil. This type of lysimeter can be equipped with different measuring probes at different depths (e.g., soil temperature, tensiometer for measuring water tension). The soil contained in the field lysimeter can either be collected as a monolith (i.e., in one piece) or be reconstructed from the different layers present at the sampling site. Most lysimeters contain an opening at the bottom allowing the leachate to be collected and analyzed over time.
