This you would unlock after completing a series of quests
Each cow you have can produce an amount of manure everyday at reset you can set it up just like truffles that’s in the game already.
The fiction of the manure would be to cut down grow times down like sunflowers and rice ect.
The cow would have to reach level 10 before it can start producing this item and higher the level the more it can produce at reset
If people were like to stock up on this item they can
Another thing you could add to this is (compost sight) and the manure that gets stored here turns in the the Fertilizer for the plants
