Fertile Soil

Fertile Soil is an event quest in Fallout 76.

Quick walkthrough

 * Go into Vault-Tec Agricultural Research Center and use the Agricultural center mainframe terminal to reset the Mr. Farmhands targeting parameters.

Detailed walkthrough
The Main Frame Terminal where you can Reset The Parameters is on the Second Floor in the Agricultural Building In a Main Office. Hint: You can't Use Quest Marker Diamonds to guide you, since they just lead you to the Doors to go Outside into Appalachia and then back inside. You just have to search the Area for the Terminal.
