An instrument for measuring the water that percolates through a certain depth of soil.
Device for measuring leaching losses from a column or block of soil. The simplest lysimeters may be devices for sampling a portion of the water leaching through a natural sediment or soil (e.g. suction lysimeter), whereas more elaborate lysimeters may involve the confinement of an entire segment of soil from which all leachate is collected (e.g. monolithic lysimeter).

a device for collecting water from the pore spaces of soils and for determining the soluble constituents removed in the drainage
An instrument for measuring the rate of percolation of rain through a soil.
An instrument for measuring the amount of water lost by evapotranspiration. It is a container of soil set on a balance or provided with some other means of measuring water content.
container of soil to measure the water movement, gains, or losses through that block of soil, usually undisturbed or in situ.
An instrument used to measure the quantity or rate of downward water movement through a block of soil, usually undisturbed, or to collect such percolated water for analysis of its quality.
A device for measuring the percolation and drainage of water through soils.
Apparatus installed in the soil for measuring percolation and leaching.

This container is then supported by a very sensitive weighing mechanism capable of detecting weight changes of less than 1 pound. Lysimeters are used in drainage and crop growth research to measure water usage, crop growth and movement of water and chemical through a soil profile.
A lysimeter is a measuring device which can be used to measure the amount of actual evapotranspiration which is released from an area of woodland. By recording the amount of precipitation that an area receives and the amount lost through the soil, the amount of water lost to evapotranspiration can be calculated.
