Re: Meaning of "within"

You have raised some valid questions. I did my dissertation on creating an expert system program for Soil Taxonomy way back in 1997. I called the people in charge of the Keys at that time, and their response was the same as I stated earlier. I suspect that when you find inconsistencies as you pointed out with paralthic and lithic depth criteria that it is an oversight left from some of the older versions and when the Keys were not in digital format. The staff at USDA-NRCS Standards should weigh in on this, but I believe that there are also a few instances where there are inconsistent wordings that are simply oversights that need to be corrected. In other cases, they can specify for you what the accurate depth limit should be.
