Abstract: Thailand, as the country faced the rapid growing of economy and energy consumption, highly demand on fossil fuel combustion both on energy sector and transportation sector lead to their massive amount of sulfur dioxide emission and deposition which therefore effect prior on the soil and its ecosystem before indirect impact to fauna and flora. This paper deal with the impact of this important substance which influence on soil chemical and the soil microorganism in some specific sensitive ecosystem like forest soil in the northern part of Thailand. With the average growth rate of 5.4 percent per year of energy consumption, the sulfur dioxide emission in estimate to be 2,956 kiloton in 2020 whichis nearly three-fold increase over the 30-Year period. The major sulfur deposition from 1990 was concentrate in Mae Moh area, the central of northern region where main power plants were located. The tropical forest surrounding the area, although no visual significant was abserved but the study of its soil properties and microorganism change shown the impact when receive critical amount of sulfur dioxide. As the soil contained high aluminum and iron, the experiment illustrated that aluminum was leached to the acid rain leachate although there was no significant change of pH in the soil. Simulated acid rain caused the reduction of bacteria actinomyces and ammonifying bacteria in the upper part of the soil"
