土 is a pictograph of a lump of earth or a mound on the ground. The horizontal lines represent the ground surface and the vertical line suggests something growing from or placed on it.
The two horizontal lines are layers of soil, and the vertical line is a plant sprouting from the earth. 土 is the ground that supports growth.
