Question

are they the same?
I possess the land and I possess of the land.

are they the same meaning? or is there any difference nuance?

Answer

''I possess of the land'' is not grammatically correct, ''I possess the land'' is correct.

Answer

The one without "of" is grammatically correct, but "possess" is a strange word here and would only be used in limited situations. Generally, you "own" land.
