Crop Evapotranspiration
A precise tool.
What is the Crop Evapotranspiration & How does it work?
Crop evapotranspiration (ETc) is a measure of the amount of water that is lost from the soil and plant surfaces through evaporation and transpiration. It is crucial for irrigation management, as it helps farmers determine how much water their crops need.
The Kc coefficient represents the ratio of crop evapotranspiration to reference evapotranspiration (ETo). It varies depending on the growth stage and type of crop. For example, a young corn plant might have a Kc value of 0.6, while a mature corn plant could have a Kc value of 1.2.

ET_c = K_c times ETo
ET_c = Crop evapotranspiration, K_c = Crop coefficient, ETo = Reference evapotranspiration

Frequently Asked Questions
What is crop evapotranspiration?
Crop evapotranspiration (ETc) measures water loss from soil and plant surfaces through evaporation and transpiration, crucial for determining crop water needs.
How does the Kc coefficient affect crop evapotranspiration?
The Kc coefficient represents the ratio of crop evapotranspiration to reference evapotranspiration (ETo) and varies by crop growth stage and type.
Why is crop evapotranspiration important for farmers?
Crop evapotranspiration helps farmers manage irrigation effectively, ensuring crops receive the right amount of water without waste.
What factors influence the Kc value for a specific crop?
The Kc value is influenced by factors such as crop growth stage, type of crop, environmental conditions, and management practices.
How do I calculate reference evapotranspiration (ETo)?
Reference evapotranspiration (ETo) can be calculated using various methods, including the Penman-Monteith equation, which requires data on temperature, humidity, wind speed, and solar radiation.
Can I use this calculator for all types of crops?
The calculator is generally applicable to a wide range of crops, but specific Kc values may need adjustment based on local conditions and crop varieties.
What are the benefits of using a crop evapotranspiration calculator?
Using a crop evapotranspiration calculator helps optimize water use, reduce costs, improve crop yield, and minimize environmental impact through efficient irrigation management.
