Abstract: 104 tobacco soil samples were collected from Chengguan, Songbai, Taochuang, Yunshan and Xiacengpu to study the the content of effective Mn in soil and its influencing factors, in order to provide theoretical basis for the improvement of Jiangyong tobacco soil and the sustainable development of tobacco industry. The results showed that: the content of effective Mn in Jiangyong tobacco soil was moderate, the average value was 19.56 mg/kg, ranged from 3.80 to 93.80 mg/kg, and the variable coefficient was 93.30%, the proportion of effective Mn in appropriate range was 49.04%. The content of available Mn in soil decreased with the increase of soil pH, organic matter, total phosphorus and total nitrogen content, and organic matter content had the greatest influence on the content of effective Mn.
