Description


The Armfield FEL6 lysimeter consists of three 300mm diameter containers in which a variety of crop types can be grown in any soil type. Each container can then in turn be placed on a hydraulically mounted plate, which is used to monitor system weight changes arising from evapotranspiration, precipitation and drainage. Despite its simplicity, the apparatus has a high degree of sensitivity and may be used for student project work as well as for demonstration purposes.



Experimental Content


  • Study of the evapotranspiration measurement by use of a lysimeter
  • Study of a lysimeter operation
  • Determine lysimeter sensitivity to gains and losses in weight at different manometer angles and to relate this to gains or losses in water
  • Demonstrate the components of the soil-plant-water system using the lysimeter
  • Measuring the variations of water loss or gain from the soil and plant due to evapotranspiration, precipitation and drainage processes
  • Demonstrate the principles of relationships between reference crop evapotranspiration, maximum and actual evapotranspiration
  • Determination of the plants water usage
  • Determine changes in diurnal evapotranspiration as measured by the lysimeter
