Fulvic Acid is an organic acid, which naturally occurs in Isparta region. In this study, the effects of Fulvic acid addition on silage characteristics were investigated. Silage corn was harvested during dough when it had 30-35% dry matter content. The plants were cut into pieces (5-6 cm in length) and then 5 kg of corn silage were put in plastic jars with 3 parallels for each group. Five different groups were formed; 1) control, 2) 0.25% fulvic acid, 3) 0.50% fulvic acid, 4) 1.00% fulvic acid, and 5) 2.00% fulvic acid groups. The control group's organic matter levels were different than 0.50% and 2.00% fulvic acid groups. The highest values of organic matter were observed in 2.00% fulvic acid groups. Crude protein levels for 2.00% fulvic acid group were different than the others. Control group crude oil values were similar with 1.00% and 2.00% fulvic acid group's values; however, 0.25% and 0.50 % fulvic acid group values were higher than the control group value. When compared to crude fiber and nitrogen- free extract values, control group values were similar to 0.25% and 0.50% fulvic acid groups but different than the 1.00% and 2.00 % fulvic acid groups. Control group crude ash values were similar to 0.25% and 1.00% fulvic acid groups but different than the 0.50% and 2.00 % fulvic acid groups. When compared to Metabolizable energy values, control group values were similar to 0.25% and 0.50% fulvic acid groups but different than the 1.00% and 2.00 % fulvic acid groups. The optimum silage pH and Fleig scores were obtained from the 0.25% fulvic acid group. According to our results, 0.25% level fulvic acid could be recommended as preservatives for silage.
