Using the filtrate of loess suspension, we cultivated soybean sprouts and investigated its effect on growth and quality in soybean sprouts. In comparison with soybean sprouts cultivated by tap water, the soybean sprouts cultivated by the filtrate of loess suspension at $20^{\circ}C$ showed increases in its weight by 11.4% and length by 14.9%. When cultivated at $25^{\circ}C$, the soybean sprouts by filtrate of loess suspension also showed increases in its weight by 9.9% and length by 11.0%. We compared inorganic element contents and pH level between the filtrate of loess suspension and tap water. Contents of Ca, Mg, K, Na, Zn, Mn, and Cu did not show any difference, while only P was higher in the tap water. pH value did not show much difference either. Consequently, it seemed that inorganic element contents and pH in the filtrate of loess suspension did not give any effect on the growth of the soybean sprouts. And also there was no any significant difference in inorganic element and amino acid contents in two kinds of soybean sprouts. However in a sensory test, the color and overall acceptability of the soybean sprouts cultivated by the filtrate of loess suspension showed better than the soybean sprouts cultivated by the tap water.
