Why would you? Barbed Field has nothing to do with producing mana -- it's merely an Aura enchantment that gives an activated ability to whichever land you choose to enchant.

For example, if you enchant a Forest with Barbed Field, it will have two separate activated abilities:

- "T: Add G to your mana pool."
- "T: This land deals 1 damage to target creature or player."

Since both of these activated abilities require tapping as a cost, you can only ever activate one of these abilities at a time. If you wanted to activate both, you would have to find a way to untap the land first, as you would be unable to tap it for the cost of the other ability without untapping it first.
