In the version of this article originally published, there was some incorrect values in the abstract, and equation 9 which has now been corrected in the online version.
Abstract:
In abstract the below sentence has been changed from:
where si, fs, and cs are the percentage of silt, fine sand, and coarse sand respectively; ISSS and FAO/
USDA is the fractionation system; and its RMSE was 3.1%. For the case that only the total sand content (s)
is available instead of fine sand and coarse sand, the following equation was obtained:
siFAO/USDA = 0.314siISSS + 1.533sISSS − 20.903 (RMSE = 3.7%)
to
