Lysimeters an overview ScienceDirect Topics

Lysimeters are foremost devices, typically tanks or containers, that define a specific boundary to contain soil water and permit measurement of either the soil- water balance or the volume of water percolating vertically and⧸or its quality. Lysimeters can be broadly defined as percolation lysimeters (sometimes called drainage lysimeters) or weighing lysimeters (Figure 1). Learn More
