This study was conducted to investigate the effects of organic materials, chitosan, wood vinegar, and EM active solution, on soil microbial and growth in Chinese cabbage. The organic materials were treated with chitosan, wood vinegar, and EM (effective microoganism) active solution, and the treatment concentration was 100 times solution and 1,000 times solution level with foliar application. The results are summarized as follows: Among foliar application of organic materials treatment plot[?], with 1,000 times solution level of chitosan was effective in inhibiting microbial growth in Chinese cabbage compared to other plots and control. The microorganism number in the soil for cultivation of Chinese cabbage increased with organic materials treatment plot as compared with control. Especially, 1,000 times solution level of chitosan showed the most significant effect.
