庚午 in the San Ming Tong Hui (三命通會)
By Wan Minying (Ming dynasty), chapter one, quoted from Chinese Wikisource; translations are ours.
Image, from the list of the sixty pillars
庚午……路旁干土
庚午: dry earth by the roadside.
Why its Na Yin is called 路傍土, from 「论纳音取象」
气当承形，物以路彰，有形可质，有物可彰
Its qi takes on form and things show themselves along the road, with form that can be given substance; the chapter adds that roadside earth is where the hundred grains are sown.
Its Na Yin against the facing one, 壁上土 (庚子 and 辛丑)
壁上路旁，形分聚散，类别死生也
Wall and Roadside: one gathered, one scattered in form; told apart as dead and living.

FAQ
Is 庚午 a good or bad pillar?
Not on its own; that depends on the whole chart, which this site does not read. Structurally, Geng has no root in 午, which clashes with 子 and combines with 未.
What is the Na Yin of Geng Wu?
Roadside Earth (路旁土), which Geng Wu shares with 辛未 Xin Wei; the Na Yin names go in pairs, 30 for the 60 pillars. The San Ming Tong Hui explains how the name was chosen in its 论纳音取象 section, quoted above.
Which years are Geng Wu (庚午) years?
Between 1900 and 2100: 1930, 1990, 2050. Each starts at Lichun, around February 4, not on January 1. Under the Chinese New Year rule the same years are the Year of the Yang Metal Horse.
