NOVELTY - Device comprises a heating unit for maintaining optimum temperature of the device using solar power, a reactor for reacting livestock excrement supplied by a excrement introducing unit with microorganisms, a stirring unit (300) with a pair of rotating stirrers respectively at lower and upper portions, installed inside the reactor, and an odor reducing unit to remove odor by uniformly mixing the liquefied fertilizer produced in the reactor with phytoncide at constant time.    USE - The device is useful for producing liquefied fertilizer based on livestock excrement using phytoncide (claimed).    ADVANTAGE - The device recycles livestock excrement, and is environmentally friendly.    DETAILED DESCRIPTION - Device comprises a heating unit for maintaining optimum temperature of the device using solar power, a reactor for reacting livestock excrement supplied by a excrement introducing unit with microorganisms, a stirring unit (300) with a pair of rotating stirrers respectively at lower and upper portions, installed inside the reactor, and an odor reducing unit to remove odor by uniformly mixing the liquefied fertilizer produced in the reactor with phytoncide at constant time. The phytoncide is obtained via a device comprising heating pipes installed inside/outside a main body (100) with wood, stems and leaf raw material of rosemary or eucalyptus, lavender or thinning-out trees including cypress, pine or oak, a steam boiler for supplying heat source with the heating pipes, a collecting plate for collecting primarily cooled distillate distilled with steam, cooling pipes for rapidly cooling steam generated at a temperature lower from material fermented inside during distillation, installed at top of the main body, and a storage tank for collecting liquid by cooling with cooling water, provided outside with primarily cooled distillate by supplying raw water to boiler, recirculating warm steam from steam returning pipe, fermenting with minimal energy, and distilling. An INDEPENDENT CLAIM is also included for producing liquefied fertilizer based on livestock excrement using phytoncide, comprising maintaining optimum temperature of the device via the heating unit using the solar heat, mixing microorganisms and livestock excrement introduced via the stirring unit and fermenting to obtain homogeneous liquefied fertilizer, and mixing obtained homogeneous liquefied fertilizer produced in the reactor with phytoncide at constant time.
