Fertilizer
In short: Fertilizer makes crops grow faster, and it never expires. Keep it in your Bag to use, or export it to your wallet and sell it to farmers on OpenSea.
Everything in Yield Fields is subject to change, including these numbers and mechanics. We'll give players ample notice before any change.
What Fertilizer does
Each Fertilizer cuts 25% of a crop's total grow time
Use up to 2 per crop, for 50%
Use one with less than a quarter of the time left and the crop ripens at once
It's used up when applied
It never expires
Only Fert Decks make it, so every farmer who wants faster harvests gets it from deed holders.
Trading it
Claim Fertilizer from your Fert Deck. It goes to your Bag.
Export it from your Bag. This mints it to your wallet as an onchain item.
Trade it on OpenSea, like any other item.
Import it back into your Bag when you want to use it in the game. Importing does not lift an exporter slowdown (see Keeping supply healthy).
Export is live as soon as staking opens. Items in your wallet can't be used in the game until you import them.
Daily export limit
Each wallet can export a limited amount of Fertilizer every 24 hours.
The limit grows with the Fert Decks you run. It is half of what your Fert Decks make in a day, counting every Fert Deck you've had running in the last 7 days. Each Common's Fert Deck adds 1.25 a day and each Mythic's adds 2.25 a day. The limit is rounded down to whole Fertilizer, so a single Common, Rare or Epic can export 1 a day and a single Legendary or Mythic 2.
Fertilizer you import back into your Bag in the last 24 hours adds to your limit.
If the game can't check your limit, export pauses until it can.
Keeping supply healthy
Nothing uses Fertilizer until farming opens, so a network-wide slowdown arrives before then to stop it piling up.
Network rate. Every hour, if the Fertilizer in circulation is above 7 days of the network's output, every Fert Deck slows down. At 10 days in circulation Decks run at 70% speed, and at 14 days or more at 50%, the lowest.
Exporter rate. It starts at 13:00 UTC on 4 November, 24 hours after staking opened. Only exports made from then on count. If a wallet exports more than 25% of its Decks' daily output in any 24 hours, its Decks slow down: 90% speed at 30%, 70% at 40% and 50% at 50% or more. That first 25% is rounded up to whole Fertilizer and never slows your Decks, so a single Common, Rare, Epic or Legendary can always export 1 a day at full speed, and a single Mythic 2. The rate updates every hour. Exports count from the moment you make them, and importing Fertilizer back does not undo them. Your rate recovers on its own once those exports are more than 24 hours old. Fertilizer you keep in your Bag never counts against you.
A Deck runs at the lower of the two rates, so it never goes below half speed. Fertilizer you hold is never taken away.
The circulation number, the target and the current network rate are public, so everyone can see where it stands.
These are launch settings and may change.
