Explain core irrigation concepts: soil?water?plant relationships, evapotranspiration (ET), application rate, distribution uniformity, and system efficiency. Interpret basic hydraulic parameters (flow, pressure, friction loss) and apply them to pipe sizing and station layout. Identify and specify key system components: pumps, filters, valves, emitters, drippers, sprinklers, sensors, and communication wiring.

Automation & Controllers

Describe the architecture of automated irrigation systems (field wiring, decoders, communication buses, sensors, fertigation units). Program
