Potential evapotranspiration

This is the maximum amount of water that would evaporate from soil and transpire from plant surfaces if water supply were not limited.

This metric is essential for calculating crop water requirements and scheduling irrigation systems efficiently. By comparing potential evapotranspiration with actual precipitation, farmers can determine the precise amount of irrigation needed to prevent crop water stress.

Proper application helps in maximizing yields while minimizing water waste. A common mistake is relying on historical averages rather than real-time meteorological data like wind speed, humidity, and solar radiation, which significantly affect the actual evaporation rate.
