Abstract
The present invention provides a method for efficiently obtaining a fertilizer containing polysaccharide hydrolysates and nutrients such as calcium, phosphoric acid, and nitrogen. The present invention is a method for manufacturing a fertilizer, characterized by comprising: a hydrolysis step for obtaining a mixture including polysaccharide hydrolysates through hydrolysis of polysaccharides using an acid catalyst; and a neutralizing step after the hydrolysis step for adding at least one basic compound selected from the group consisting of potassium salt, phosphate, ammonium salt, and ammonia.
Claims14
A method for producing a fertilizer, comprising:
- a hydrolysis step wherein a mixture containing a polysaccharide hydrolysate is obtained by hydrolyzing a polysaccharide with an acid catalyst, and
- a neutralization step wherein, after the hydrolysis step, at least one basic compound selected from the group consisting of potassium salts, phosphates, ammonium salts, and ammonia is added,
- wherein
- the hydrolysis step is performed by a mechanochemical method, and
- in the mechanochemical method, one or more pulverization devices selected from the group consisting of rolling ball mills, jet pulverizers, shear mills, colloidal mills, impact pulverizers, vibration mills, and planetary ball mills are used in a pulverization process.
