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.
Table 3. The standard deviations (sd) and coefficient of variations (cv) of four cross validations by using multiple regression equations (8) and (9)
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%)
