method for manufacturing liquid fertilizer containing sericite ingredient

摘要

The present invention relates to a method of extracting minerals from sericite to produce an alkaline solution. More particularly, potassium, calcium and sodium contained in sericite are extracted more to promote the growth of crops, The present invention relates to a method for producing a liquid fertilizer which can be neutralized with soil. The method of the present invention can extract more potassium, calcium, and sodium, which are inorganic fertilizer components, from cerosis by a simple operation, and can reduce the energy source required in the extraction process, In addition, the slurry produced by the method of the present invention exhibits alkalinity, thereby neutralizing the acidic soil to prevent acidification of the soil.
