The effects of briquette ashes on the growth of vegetable (cabbage, lettuce, spinach and radish) and their fresh weight under the culture of the soil mixed with the briquette ashes, and on the chemical properties of the soil were investigated. The growth rate of these palnts and chemical properteis of the soil has shown some influence due to different concentration of briquette ashes added to the soil. The increase of growth in cabbage and lettuce was remarkably found by the plot treated with 1/50 concentration of briquette ashes. The fresh weight of vegetable plants was increased with high concentration of briquette ashes, but if the concentration of briquette ashes was too high, it was rather depressed. Chemical properties in the soil after cultivation of the plants were more depressed than before cultivation. In contrast the available nitrogen content in the soil after cultivation was more increased than before cultivation of the plants. The reduction of available nitrogen and nitrate nitrogen was associated with the increasing intensity of briquette ashes, but available phosphorus content was increased with high concentration of briquette ashes, though its content was not so high as the results obtained by Han(8). The values of total exchangeable base and pH in the soils treated with briquette ashes were increased with a high degree of the concentration of ashes. The value of pH was not significant, and pH value of lime plots was higher than that of briquette ashes. The average value of the water content did not show any difference, and the difference of the content of organic matter in the soil in which different vegetable grew into the plots reached to the significance of a 5% level.
