Why did plantations requires large labor force?

Plantations required a large labor force primarily due to the labor-intensive nature of cash crop cultivation, such as sugar, tobacco, and cotton, which demanded extensive planting, harvesting, and processing activities. Additionally, the scale of production aimed at maximizing profits necessitated a significant workforce to meet the high demands of both planting and maintaining large tracts of land. This labor-intensive approach often led to the reliance on enslaved individuals or indentured servants to fulfill the labor needs, particularly in the Americas during colonial times.
