Abstract
Physicochemical properties of liquid fertilizer samples of resource organization, which are domestically produced and distributed, are analyzed. Major contents of the research results are as follows. 1. The ratio of complete decomposition for liquid fertilizer is 49% at Public Resource Center and 33% at Liquid Fertilizer Supply Center. The combined ratio of both half-decomposed and un-decomposed liquid fertilizers is over 50% at both centers. 2. The ratio of complete decomposed liquid fertilizer, 67%, is the highest in Gangwon and Gyeonggi-do area. The ratio of un-decomposed liquid fertilizer is high in Chungbuk and Chungnam area. The sum of ratios of the half- and un-decomposed is over 60% in the areas except Gyeonnggi-do and Gangwon-do. 3. As a result of regional comparison of the physicochemical properties of liquid fertilizers, concentration variation in most of the items are large, and the degree of uniformity is found to be considerably low. In particular, concentration variation in T-N and $NH_4$-N is the most noticeable. 4. The items that physicochemically correlated to the degree of decomposition of liquid fertilizer are appeared to be T-N, $NH_4$-N, $NO_3$-N, EC, $SCOD_{Mn}$, and ORP. 5. The physicochemical average values of the liquid fertilizer estimated as "complete decomposed" are appeared to be T-N 829 mg/L,$NH_4$-N 517 mg/L, $NO_3$-N 151 mg/L, $SCOD_{Mn}$ 1,205 mg/L, EC 10.32 mS/cm, ORP -117.12 mV.
