Farm

A farm increases the nutrients production of a square by +1. Farms cannot be built in rocky squares.

Background
Terraformers devoted much time and energy to converting wilderness to farmland. Native flora had to be eradicated and plowed under, and irrigation systems had to be built. Once Earth-born crops were planted, they required constant attention to protect them from native diseases and marauders. This work was labor-intensive at first. Even after the spread of agricultural robotics, farmers lived out on the land for weeks or months at a time.
