重量％の範囲が好ましい。Since the by-product of the titanium oxide by the sulfuric acid method usually contains water in the range of 30 to 60% by weight, if it is used without removing it, it is not necessary to use a wetting agent during molding. If the water content is out of the above range, the desired effect cannot be obtained, and if the water content is more than 60% by weight, a fluidized state is formed and molding becomes extremely difficult. Therefore, adjustment is performed by operations such as drying and dehydration. Further, since the by-product exhibits neutral to weakly alkaline, when the by-product is applied to a plant suitable for acidic soil, the pH of the by-product is adjusted to a weakly acidic region by using sulfuric acid, hydrochloric acid or the like, preferably at pH 5. Adjust to a range of 0.0 to 7.0 and then form into granular soil. Alternatively, a solid acidic substance such as iron sulfate or magnesium sulfate may be added in the step of forming the granular soil or after the forming.
The amount of solid acidic substance contained in the granular soil is 0.1 to 5
A weight% range is preferred.
