COLLAPSIBLE GRANULAR COMPOSITION CONTAINING AMORPHOUS FERTILIZER COMPOSITION, MANUFACTURING METHOD THEREFOR AND FERTILIZER OR SOIL IMPROVEMENT MATERIAL CONTAINING THE COLLAPSIBLE GRANULAR COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a collapsible granular composition containing an amorphous fertilizer composition derived from chicken droppings combustion ash and ferronickel slag, a manufacturing method therefor and a fertilizer or a soil improvement material containing the collapsible granular composition.SOLUTION: There are provided a collapsible granular composition which contains an amorphous fertilizer composition obtained by heating and melting a composition by adding ferronickel slag to chicken droppings combustion ash and further mixing an auxiliary feedstock if needed and then cooling them, contains a phosphorus component dissolved in 2 wt.% citric acid solution of 6 to 16 wt.% in terms of PO, a potassium component dissolved in 2 wt.% citric acid solution of 3 to 10 wt.% in terms of KO, a silicon component dissolved in 0.5 mol/liter hydrochloric acid solution of 20 to 40 wt.% in terms of SiO, a magnesium component dissolved in 2 wt.% citric acid solution of 10 to 30 wt.% in terms of MgO, a calcium component dissolved in 0.5 mol/liter hydrochloric acid solution of 5 to 30 wt.% in terms of CaO and having a value of the MgO/SiOin terms of molar of 0.65 or more and an organic product-containing granulation auxiliary which is at least one kind selected from starches, a Steffen waste water concentrated liquid, an alcohol ferment waste liquid concentrated liquid, lignin sulfonates and blackstrap molasses, a manufacturing method therefor and a fertilizer or a soil improvement material containing the collapsible granular composition.SELECTED DRAWING: None
