It is due largely to the salt in the soil during desertification. It is emitted by large amounts of industrial waste from domestic thermal power plants. Among them, Bottom Ash has a salt blocking effect. Bottom ash is a byproduct of a thermal power plant that collects discontinuous residue attached to the chimney wall and drops it to the floor by gravity. In the study of the Korean Society of Soil and Fertilizers, the effects of improving the growth of plants were tested using these BAs. As a result, normal growth was shown only in the BA treatment sphere. So we found that BA was effective in blocking the flow of water from the lower levels.
