What does a lysimeter measure?
Think about the water cycle and its components.
Name one research center in India that uses lysimeters.
Consider major agricultural research institutions.
What do lysimeters primarily measure?
They track water evaporation and plant transpiration.
True or False: Lysimeters can be used on a large scale for general crop irrigation.
Consider the practicality of using this tool.
A researcher established a lysimeter to study cotton crops. The weight before watering was 100 kg, and after a week, it is measured at 90 kg. What is the total water loss in this case?
Use the change in weight to calculate water loss.
Consider a scenario where a crop coefficient for wheat is established at 0.8. If the reference evapotranspiration (ET₀) is 50 mm, how much water should be applied to match the crop's needs?
Multiply the crop coefficient by the reference ET.
