A lysimeter is a measuring device which can be used to measure the actual evapotranspiration which is released by plants. 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.

What is lysimeter experiment?

Lysimeter experiments were conducted to determine the ability of different soils to reduce levels of biochemical oxygen demand (BOD) and concentrations of molybdate reactive phosphorus (MRP) and ammonium-N (NH4(+)-N) in dirty water and the impact of applications on nitrate leaching.

How is a lysimeter installed?

Due to the shallow nature of the lysimeter design, the units were installed by hand. A 15-cm diameter hole was dug using the hand auger and post hole digger. A larger 34-cm hole was then dug around the borehole to a depth of 36-cm.
