Visitor visa for Parents, Father has agriculture land and working full time

[brankd]

I am PR here and applying visitor visa for my parents. My father has full time job and file income tax every year. But he does not have any documents in English for agriculture land that he owns. Is it okay if I do not show that he has agriculture land?
If no then what documents he needs to show for agriculture land? He could not able to get J form.
