Suggest me Compressor or submersible?

Dear Farmnest Members,
We have bore well of about 1060 feet depth and water is at 600 feet (400 feet water is there).
Please advise whether to go for a submersible motor or fix a compressor motor with increased hp. please suggest the hp for the motor you suggest.
From this water how many acres i can plant vegetables.
*Free Electricity available.

Thanks
Karthi
