Abstract
This study was carried out to investigate the characteristics of the organic liquid fertilizer and find out optimum fermentation conditions of Effective Microorganisms (EM) including ascidian tunic. During the EM fermentation by adding ascidian tunic, electrical conductivity (EC) was increased, contrast to decrease the pH value, on related to the initial dosage molasses rate. Additionally, the total nitrogen quantity was shown to be increased on EM fermentation and the most effective increasing was recorded up to 220% on more than 15% molasses dosage condition. The phosphorus quantity was to be maximum rate on 21th of EM fermentation, and other contents, such to potassium, calcium, magnesium, sodium, had be shown an increasing patten during the fermentation period. After the EM fermentation, the concentration of hazardous material (Zn, As, Cd, Cu, Cr, Hg, Ni, pb) was measured below than the official criteria for commercial fertilizer. As a effective material in fermentated fertilizer, the 29 kinds free amino acids were detected and their total concentration was measured to 7080.94 mg/L.
