ET-based Irrigation
ET-based Irrigation (where ET stands for Evapotranspiration) is a smart approach to watering crops and landscapes that uses weather data to determine exactly how much water plants need. Think of it as a scientific way to avoid over or under-watering by measuring how much water evaporates from the soil and is used by plants. It's like having a smart thermostat for watering - instead of guessing when to water, the system uses real weather information to make better decisions. This method is becoming increasingly popular as farms and businesses try to save water and money while keeping plants healthy.

Example Interview Questions
Senior Level Questions
Q: How would you implement an ET-based irrigation system for a large agricultural operation?
Expected Answer: A strong answer should explain the process of assessing the land, selecting appropriate weather stations, setting up monitoring systems, and creating water management schedules. They should mention cost considerations and ROI calculations.
Q: What strategies would you use to optimize water efficiency in different climate zones?
Expected Answer: Should discuss adapting irrigation schedules to local weather patterns, using historical climate data, and implementing fail-safes for extreme weather conditions. Should mention experience with different crops and soil types.
Mid Level Questions
Q: How do you calculate daily ET rates and adjust irrigation accordingly?
Expected Answer: Should be able to explain the basic process of gathering weather data, using ET calculation formulas, and adjusting watering schedules based on results. Should mention practical examples from their experience.
Q: What factors do you consider when programming an ET-based irrigation controller?
Expected Answer: Should discuss soil type, plant type, root depth, slope, and local weather patterns. Should demonstrate understanding of seasonal adjustments and maintenance requirements.
Junior Level Questions
Q: What is evapotranspiration and why is it important for irrigation?
Expected Answer: Should be able to explain in simple terms that ET combines water loss from soil evaporation and plant transpiration, and why this matters for determining watering needs.
Q: What basic components make up an ET-based irrigation system?
Expected Answer: Should identify main parts like weather stations, controllers, sensors, and explain their basic functions in simple terms.
