Question

How did the cotton gin make upland farming profitable?

Answer 1

Upland farmers, however, had little choice, and their widespread use of Whitney's design greatly expanded southern cotton production. ... While the cotton gin reduced the amount of labor required to remove the seeds from the plant, it did not reduce the number of slaves needed to grow and pick the cotton.

Answer 2

Since cotton was so hard to clean, the invention of the cotton gin made life easier for farmers since they would not have to clean the cotton manually and this way they had more time to concentrate on planting cotton crops thus increasing the production of land.

EXPLANATION:

Moreover, farmers also had slaves to assist them, and they made some of the slaves to use the cotton gin and some others assisting farmers collect the cotton. Cotton growing and production became so lucrative for farmers that it had raised the demand for both land and slaves.
