A Soil Suction Lysimeter is a device used to measure the water content and soil suction (or matric potential) in the soil. It helps farmers and land managers use water resources more effectively. This is used in studies related to soil hydrology, groundwater recharge, and ecosystem dynamics. They can be made of materials like plastic or metal, designed to allow water movement but prevent soil loss. The primary purpose of a Soil Suction Lysimeter is to evaluate how water moves through the soil profile, particularly in relation to plant roots.
