Yes! Check this out!
Other players have decided to go for grain-producing plots only. This is because Grain is the basic resource that every land worker would need to consume (at least right now) in order to function. Workers in the Grain plot consume a portion of what they harvest so this is more of a set-and-forget approach. Just claim at least once a week right before the worksite hits max capacity.
Others would prefer to go the self-sufficiency route meaning they have grain plots, and they have others. All the grain the workers need can be self-produced. For example, 1 Grain Plot and 1 Stone Plot. Just make sure that you yield enough grain from your grain plot to feed the workers in your Stone plots.
Feel free to ask more questions! ;)
