Evapotranspiration
The sum of evaporation from the soil surface and transpiration from plants into the atmosphere.

Evapotranspiration is a fundamental metric used to estimate the water requirements of crops. By quantifying how much water is lost to the atmosphere, producers can determine the precise amount of irrigation needed to ensure healthy plant development.
Applying this data helps in managing irrigation schedules efficiently, which prevents water stress during critical growth stages. Using sensors or weather-based models allows for a more tailored approach to water management, significantly improving water use efficiency.
A common mistake is failing to adjust calculations based on the specific crop growth stage, as water demand varies significantly from seedling to harvest. Overlooking local weather patterns, such as wind speed and humidity, often results in inefficient water application.
