The kanji 増 is a phono-semantic compound (形声文字 - keisei moji). The left side is a component from 土 (tsuchi), meaning "earth". The right side is 曾 (sō, meaning "once"). This originally depicted a rice field that had become larger, hence representing an increase. The phonetic component 曾 contributes to the sound of the character. Over time, the meaning shifted to a general sense of increase or addition, extending beyond just the growth of agricultural products.
