PURPOSE: A manufacturing method of a disposable golf ball for field hitting practice is provided to enable a user to practice golf while feeling hitting a ball in a field. CONSTITUTION: A manufacturing method of a disposable golf ball for field hitting practice is constituted as follows. In a raw material grinding process, mixture is shattered into pieces through a pulverizing device. In a deodorization process, the pulverized raw material is poured in a biofilter deodorizing device for 10-20 minutes and bad smell is removed. In a core formation process, a deodorized raw material is mixed with distilled water and starch and is poured in a compression molding machine. In a drying process, the core is poured in a dryer and is dried at 80-100 deg.C for 15-30 minutes. In a coating layer formation process, a coating layer made of biodegrading plastic and natural dye is formed in the outside of the core. In a semi-drying process, a molding is inserted into the dryer and is semi-dried at 30-50 deg.C for 5-10 minutes. In a dimple molding process, a dimple is formed in the outside of the molding.
