Abstract:
For accurate and reliable measurements of different components of crop hydrologic cycle the lysimeters should be constructed, installed and operated properly. The installation of lysimeters must meet several design requirements for the data to be representative of field conditions. Some design requirements on lysimeters depth, water control, drainage, area, wall, filling of soil, soil moisture, soil heat flux and comparability of plant cover are discussed which may be helpful in a proper installation of lysimeters.
