New classes for soil texture categories

[celineaubert]

USDA uses its triangle technique to determine soil texture http://www.nrcs.usda.gov/Internet/FSE_MEDIA/nrcs142p2_050242.jpg

• USDA triangle technique soil texture catagories: sand, loamy sand, sandy loam, sandy clay loam, sandy clay, loam, clay loam, clay, silty clay, silty clay loam

FAO has 2 techniques to determine soil texture, and these techniques have there own soil texture scale.

• FAO Ball and ribbon method soil texture categories: sand , loamy sand , sandy loam, loam, heavy loam , light clay, clay
• FAO ball throwing technique soil texture categories: loamy sand , sandy loam , medium texture (loam, sandy clay loam, silty clay loam), clay loam, clay

Would it be possible to create a new class for each of this soil texture and tag them with the technique they belong to?
