Fertilizer Plants/Factories: Produces fertilizer which, when built on a planet that has a smidgen to plenty Baobabs and or Space Oats, will increase productivity by allowing the player to use more Tree Cutters and or Harvesters.

A Small planet could support up to 4(TBD) Fertilizer Plants.
A Medium planet could support up to 6(TBD) Fertilizer Plants.
A Large planet could support up to 8(TBD) Fertilizer Plants.
Fertilizer Plant construction and build costs (TBD).

The more plants built on a planet means you can use more Tree Cutters and or Harvesters. (ratio TBD, I suggest a 10-15 to 1 increase... for every Fertilizer Plant built 10-15 additional Tree Cutters and or Harvesters could be added to the base.)
