"Villagers gather Coin faster."—In-game description
Earth Gift Ceremony is a technology in The WarChiefs that can be researched by Native American civilizations at the Plantation once Earth Ceremony is researched. Once researched, it allows Villagers to gather coin 20% faster. Excessive Tribute is the further upgrade of this technology.
Earth Gift Ceremony makes it important for Native American players to build a Plantation somewhat early, even if they're still gathering coin from mines.
