NOVELTY - Method for manufacturing compost involves (a) forming pruned branch leaf material by crushing pruned branch leaf and producing pruned branch leaf material, (b) depositing the pruned branch leaf material on a deposition place, and forming a deposited material, (c) spreading the nutrients produced from the fermentation treacle, and adding water to the deposited material, stirring the deposited material, fermenting the deposited material, and (d) again spreading the nutrients in fermented deposited material and again fermenting the deposited material.    USE - The method is useful for manufacturing compost (claimed) which is used for plants and agricultural products chosen from Japanese radish and tomato.    ADVANTAGE - The method manufactures compost in short period of time, preferably 40 days with out using livestock excrement as additive. The compost improves nutrition absorption rate of roots, water holding capacity and fertility retention of plants as it contains outer layer of onion.    DETAILED DESCRIPTION - Method for manufacturing compost involves (a) forming pruned branch leaf material by crushing pruned branch leaf and producing pruned branch leaf material in substantially cylindrical shape, (b) depositing the pruned branch leaf material on a deposition place, and forming a deposited material, or performing deposition process by adding agricultural product residue work material to the pruned branch leaf material, depositing the mixture of the pruned branch leaf material, placing agricultural products residue work material on the deposition place, and obtaining deposited material, (c) spreading the nutrients produced from the fermentation treacle, and adding water to the deposited material, stirring the deposited material, fermenting the deposited material in controlled temperature and carrying out predetermined period fermentation of the stirred deposited material in the deposition state under air release, and (d) performing nutrient spreading process which spreads the nutrient again to the fermented deposited material, stirring the deposited material again to spread nutrients, and again fermenting the fermented deposited material.
