Abstract:In this paper, fly ash discharged from the power plant was used to study the effect of various addition amount applied to clay soil on wheat yield and its after-effect. The result showed that the effect of fly ash on improving clay soil was obvious. Wthin a certain limit, it could be affected directly on the growth, development and yield of wheat, especially when the ad dition amount of fly ash was 25-40 ton per mu.
Keywords:Fly ash Clay soil After-effect
