Namashkar,
The document will not help to get a farmer status for you. You cannot achieve farmer status in Gujarat. The only way is through family, which is not true in your case.
You may look into other states.
Gujarat is the most strict regarding farming status.
Dear Colleagues,
I am looking to buy ~ 20 acres of agricultural land in or around ahemdabad.
Interested sellers/consultants you may contact me at my email
Regards
Viren
