Title:
METHOD FOR MANUFACTURING ORGANIC FERTILIZER, METHOD FOR CULTIVATING PLANT, METHOD FOR IMPROVING SOIL, AND APPARATUS FOR MANUFACTURING ORGANIC FERTILIZER
Document Type and Number:
WIPO Patent Application WO/2022/080479
Kind Code:
A1
Abstract:
A method for manufacturing an organic fertilizer with an enhanced nitrogen content, the method comprising a step of treating an organic fertilizer with nitrogen plasma. Further, a method for cultivating a plant, comprising a step for manufacturing an organic fertilizer having an enhanced nitrogen content by the manufacturing method, and a step for cultivating a plant in the soil to which the organic fertilizer has been applied. Further, a method for improving soil, comprising a step of manufacturing an organic fertilizer having an enhanced nitrogen content by the manufacturing method, and a step of applying the organic fertilizer to the soil. An apparatus for manufacturing an organic fertilizer having an enhanced nitrogen content, the apparatus comprising: a plasma generation unit, a nitrogen gas supply unit that supplies nitrogen gas to the plasma generation unit, and an organic fertilizer holding unit that holds an organic fertilizer, wherein the organic fertilizer held by the organic fertilizer holding unit is irradiated with nitrogen plasma generated by the plasma generation unit.
