Abstract
This study was carried out to develop a more convenient way to analyze soil texture by hydrometer. Standard Hydrometer Method(SM), in which at least 7 times of reading is required for soil texture analysis, was compared with two other methods named as Soil Clay Fraction Procedure(SCFP) and Simplified for Soil Texture Analysis(SSTA), in which 2 or 3 times of hydrometer reading may be enough for soil texture analysis, respectively. There appeared to be very close correlation(nearly 1.0) between clay contents measured by the above three methods. The clay content measured by SCFP were overestimated by 0~2 percent than those by SM. Textural classes of 28 soil samples determined by SSTA were identical to those by SM. But, textural classes determined by SCFP appeared to be different from those by SM in 4 of 28 soil samples. Because the measurements of particle size in SSTA is made near
