Warning this is NOT a stack! This is 30 Fertilizer. Perfect for one Large Crop Plot! Storing Fertilizer can be difficult since it does not stack at all. However, with their low weight, storing lots of Fertilizer in a dino can prove to be the most efficient way of storing them. Every creature can hold a maximum of 300 stacks of items. This means something as simple as a Dodo or a Kairuku will be able to hold 300 Fertilizer and still have plenty of carry weight left over.
