Is charcoal needed...

...in a planted tank filtration system?

I know the purpose of charcoal is to remove impurities, but what about fertilizers? Does it reduce fertilizer effectiveness as well?

If you want to grow plants, you want to avoid activated charcoal, because these impurities that it removes are often necessary for plant growth.

None of my tanks use charcoal, weather it be discus breeding tanks, planted, or salt water.

Activated charcoal will remove the chelated metals (micronutrients) from the water column, but will leave the macronutrients alone.

As such, you will want to avoid using activated charcoal.

Finally, many people on these forums use Purigen as an alternative to activated charcoal, as it is supposed to leave the nutrients alone.
