Abstract: A field trail was carried out to evaluate the effect of application of microbial agents (EM) and humic acid potassium (HA-K) on tobacco cv. Yunyan 87 in Ji'an, Jiangxi Province. It was shown that combined application of EM and HA-K could increase microbial population, enzymatic activity, soil nutrient and pH value. The effect of combined application of EM and HA-K was better than that of individual application. Single application of EM or HA-K significantly increased leaf yield and economic benefits, but the effect of combined application of EM and HA-K was better.

Key words: humic acid potassium, microbial agents, soil amelioration, economic benefits
