To provide more exact name of this soil it is necessary to find profile description of this soil, as detailed and possible. Than it would be useful to check "Keys to soil Taxonomy" (the newest can be found here: https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/class/?cid=nrcs142p2_053580, however, it would be recommendable to use the keys from the years before the description of this particular soil), but absolutely necessary is to check WRB2014 (here: http://www.fao.org/3/a-i3794e.pdf), going through the key provided there to attribute other qualifiers.
