The quantity of material that can be held in a shovel at one time.
He filled the wheelbarrow with a shovelful of dirt.
Shovelful is formed from "shovel" (from Old English *sceofol*, meaning a tool for digging or lifting) and "-ful" (meaning full of). The word "shovelful" refers to the amount that a shovel can hold, or being full of what a shovel can carry.
Think of a shovel being 'full of' something — that's what shovelful means.
