Fertile volcanic acre

Fields and meadows Obsidian farm

The fertile volcanic field is purely an investment in space paid for in gold, not a route to higher production, so it only makes sense where you're genuinely running out of room.

What it's for

Fertile volcanic acres allow you to grow various crops very space-efficiently.

Produces

Rye

The fertile volcanic field is a smaller version of the volcanic field on the Obsidian farm - it fits into a 6x6 area instead of 8x8 and produces exactly the same crops, rye, saffron, sage, tomatoes and king salmon. The difference is that you pay for the whole building and all its upgrades purely in gold, not in obsidian dollars. It unlocks at level 114, same as the ordinary field. It's a choice for players who are running out of space on the farm and are willing to pay premium currency for the space they save.

When to build it

Only build it when you're short of space on the Obsidian farm and have gold to spare - otherwise an ordinary volcanic field for obsidian dollars is cheaper and just as productive. It pays off most when your farm is almost full and you need to squeeze another source of materials into a smaller spot.

Is it worth upgrading

The production numbers are completely identical to the ordinary field - 23 rye, 45 saffron, 75 sage and 28 tomatoes in the same times, at level 1 just like at the highest level 6. The upgrade price grows from 2000 to 30000 gold and the build time stretches from 15 minutes to 21 hours, but you won't get a single unit more out of the harvest for it. Upgrading it with gold therefore isn't worth it for the yield, only because you need the higher level if you want the farm unlocked further beyond player level 114.

Tip from a veteran player Don't spend gold on higher levels of this field until you really need the space it saves - for the same gold you'll usually get more useful things, and the materials from the field will be the same whether you're at level 1 or 6.

Most common mistake Because the field costs gold, players think it must produce more than the ordinary volcanic field - in reality the yield is identical, the only difference is the smaller footprint.
