Hello

Because in SWRC fit I need to add soil texture type. I have a question that what soil texture classification system is used, usda, WRB or others. Maybe it is shown somewhere but I am sorry for not finding that.

Thank you

The sample data of SWRC Fit are from UNSODA database, as written in the page of SWRC Fit. UNSODA database uses USDA classification system. SWRC Fit does not use the information of soil texture for determining the model parameters. If you make your own analysis of your SWRC data, you can use any classification system that you like and describe it in your result.
