This invention provides a silicic fertilizer using a slag produced in a preliminary treatment of a molten pig iron and imparted with a high soluble silica content, and a production method of such a silicic fertilizer. CaO is added and oxygen is blown into a molten pig iron while adjusting a basicity (CaO/SiO ) to 3 or below, and the molten pig iron is subjected to desiliconization and dephosphorization. The resulting slag is collected to produce the silicic fertilizer. This silicic fertilizer has a basicity (CaO/SiO ) of not greater than 3 and contains 15 to 35 mass % of soluble silica.

Silicic fertilizer and production method thereof

A child safety seat can be used as an auxiliary seat in an automobile and a stroller. The child safety seat has front and rear caster arms which are rotatably provided in a seat structure. The front and rear caster arms selectively extend downward from and retract above the lowermost portion of the seat structure. The child safety seat can be attached to the automobile seat when the front and rear caster arms retract.
