how can i use bitcoin to improve my plantation farm? Does it mean farmers cannot use bitcoin to improve their peasant or plantation farm?
You can only do is to accept bitcoin as one of your payment in your farm. As bitcoin is just a way for investment, nothing more. Related to your plantation, if you can find clients to accept bitcoin you can do it as well or just convert it to fiat.
Bitcoin or Blockchain can't solve every problem in this world though.
