Liquid fertilizer manufacturing method, compost manufacturing method and no-tillage cultivation method

摘要

PROBLEM TO BE SOLVED: To provide a method for producing liquid fertilizer using a poultry waste fermented product with suppressed odor generation which facilitates work on a working site and contains abundant useful components, and also to provide a method for producing compost using the liquid fertilizer acquired by the method for producing liquid fertilizer which eliminates the need to cutback and reduces burden on a working site and a no-tillage farming method.SOLUTION: A method for producing liquid fertilizer includes an immersion step in which at least either incineration ash or a carbide, soil bacteria and a poultry waste fermented product containing poultry manure are immersed in water to convert them into an immersion product and a fermentation step in which the immersion product is maintained in an anaerobic condition at a water temperature of 25-35°C for three days or more. Liquid of the immersion product after the fermentation step is used as liquid fertilizer.
