A most intriguing land

There is a land where a thing turns to nothing
Where money is then discovered
Where a place becomes unknown
Where farming turns into a spectacle
Where the flora is actually worlds
Where a pipe can be mounted into battle
And where many becomes all

Where is this land?

The land is

NOWHERE

Reasoning:

Every line gives two definitions of two words. The second word is the first one plus one letter.

There is a land where a thing turns to nothing

one -> None (credits to @Tom)

Where money is then discovered

fund -> fOund

Where a place becomes unknown

here -> Where (a stretch, maybe...)

Where farming turns into a spectacle

sow -> sHow

Where the flora is actually worlds

plants -> planEts

Where a pipe can be mounted into battle

hose -> hoRse

And where many becomes all

very -> Every
