摘要
PROBLEM TO BE SOLVED: To provide a manufacturing method of a new potassium phosphate compound fertilizer capable of validating a phosphoric acid component contained in incinerated ashes of poultry dung by improving its solubility and at the same time having a powdery form with good handling that is obtained by neutralizing an alkali derived from a lime component, and a new potassium phosphate compound fertilizer.;SOLUTION: The problem can be solved by adding an alkaline earth metal compound to incinerated ash powder of poultry dung, adding a mineral acid to this so as to cause a neutralization reaction between the added alkaline earth metal compound powder and the added mineral acid, raising the temperature of the reaction system by utilizing the heat build-up at the neutralization reaction, accelerating a reaction between the mineral acid and a lime component or the like contained in the incinerated ash of poultry dung, converting a phosphoric acid component to a citric acid-soluble phosphate, and at the same time keeping the product in a neutral or weakly acidic range.;COPYRIGHT: (C)2007,JPO&INPIT
