Hello,
I am a student researching the precontact cultivation of tobacco by Indian tribes in western North America. I am trying to find a map of the 12 basic soil classes (clay, loam, silt loam, etc) but am having trouble. This would allow me to note where nicotiana species have proliferated despite regions being outside of their “natural” range. I am accounting for other geospacial factors as well, but this would be extremely helpful. Any assistance would be greatly appreciated 🙂
