| Abstract: | Pot experiments were conducted on paddy soil, and the effects of slag application on soil pH, silicon forms, and silicon content in plant were studied. The results showed that, comparing with the control, the pH value, the soil active silicon, available silicon content in soil and silicon content in plant were increased. On the contrary, soil water-soluble silicon and amorphous silica content in soil were decreased than that of the control. These effects were evident with the increase of the amount of slag application and the decrease of the particle size except the treatments of different particle size of slag in water-soluble silicon content. |
