The invention discloses an organic innocent fertilizer and a production method thereof. The organic innocent fertilizer consists of the following components in percentage by mass: 20 to 40 percent of cottonseed meal, 10 to 30 percent of decomposed chicken manure, 10 to 30 percent of plant ash, 10 to 30 percent of humic acid, 0.5 percent of biological fertilizer strain and the balance of water, wherein one gram of biological fertilizer strain contains 0.2 billion effective viable bacteria; the production method for the organic innocent fertilizer comprises the following steps of: 1, adding water in an amount which is 30 percent of the total amount of the cottonseed meal into the cottonseed meal, and sealing and fermenting at the temperature of between 30 and 35 DEG C for 72 hours for later use; 2) disinfecting the decomposed chicken manure at the temperature of 100 DEG C for 3 hours; and 3, uniformly stirring the fermented cottonseed meal, the disinfected decomposed chicken manure, the plant ash, the humic acid, the biological fertilizer strain and an appropriate amount of water in a proportion, and pelletizing by using a steam pelletizer. By the organic innocent fertilizer, the hardened soil can be gradually improved, the organic matter in the soil can be gradually increased, the quality of soil can be recovered gradually, the ecological environment is improved, the yield and quality of agricultural products are improved, and the agriculture is returned to the sustainable development track.
