Question

of the 3 types of irrigation methods, which one is the most efficient?
digging trenches
drip
sprinklers
splash

Explanation:

Drip irrigation delivers water directly to plant roots, minimizing evaporation and runoff, making it the most efficient among common methods. Digging trenches is less efficient as it can lead to water loss. Sprinklers can waste water through evaporation and wind - drift. "Splash" is not a standard irrigation method.
