Makes crop fields with no icons overhead and no workers needed, which cover the ground with two different shades of green grass depending on which one you use. You can choose to plant on the land as long as you check manually for workers and so forth, since there are no icons. Imagine it as someone planting tomatoes in their lawn. Minimum size is 2x2.
Version 1.1 has a minimum size of 1x1.
