Below are some map links that may help you determine where you would like to farm in Maine.
If you become interested in a particular farm, be sure to obtain the soil maps of the area. See Map below
The Department of Agriculture has a Soil Scientist who would be able to come out to a property with you, test the soils for free and give you the data you are needing to determine if the land you are looking to buy/grow on is the right fit for your goals. Contact:
