This study was conducted to investigate the effect of woody chared materials on the injuries and growth of plant, and chemical properties of soil in the continuous cropping field of red pepper. The field for the experiment was selected among districts, where have been taking place seriously injuries by continuous cropping of red pepper for above 20 years. The growth of red pepper was promoted and the growing period was prolonged about 2 weeks longer than that of control, and yield was increased with the increment of charcoal application amount. The occurrance rate of phytopthora blight disease was 9% lower at charcoal 500 kg/l0a application treatment than at control in the experiment of application amount of the first year, but was not significantly different between sizes of charcoal. The mix of charcoal and pyroligeous liquor had no effect on the growth of red pepper. In applicated soil of charcoal, pH was increased, EC was decreased, and Ca and Mg content was low somewhat. In all, charcoal granule was most effective type. The B/F value of soil was higher at the charcoal powder treatment on July 18 than other treatment, but was no difference between treatments in anytime else.
