Which irrigation method is NOT considered one of the three main types used in commercial horticulture?

Explanation:
Fogging irrigation is not considered one of the main irrigation types because it’s primarily used for humidity control and cooling in greenhouses, not for delivering water directly to the root zone. The three main types of irrigation in commercial horticulture are overhead sprinkler systems, which apply water from above; drip (micro) irrigation, which delivers water directly to the root zone through emitters; and subirrigation, which supplies water from below. Fogging can moisten leaves and air, but it’s not a reliable or efficient method for consistent soil moisture management like the other three.
