Once again, you have done well with the changes made so far. A few more minor things:
“Sugar Plantation” is not a proper noun. It was in previous drafts when you mentioned one specific plantation, but it is not now.
In US usage, we would not say “yield the cane.” Do you mean “harvest?” Again, if this is proper Australian usage, please disregard.
I think you mean “banks” and “loan” in your fifth sentence.
In the next sentence, perhaps you should say “the mechanization of the cutting process.” Or you could say “using machines instead of human labor in the cutting process…”
In the next sentence, it would be better to say either “change in technology” or “technological change.”
In the sentence that begins “After a clash arose…” you might want to specify what “trade” you are talking about.
Finally, “desisted” is not used in the best way here. People “desist” when they stop doing something. The trade can’t desist because it’s not the actor. So, maybe just say “when the trade ended…”
