Pig manure fermentation organic fertilizer
1. Prepare material and add bacteria: Prepare feces that need to be fermented, preferably fresh pig feces (fresh feces has better fermentation effect than old feces). For example: fresh pig feces is about 1 ton plus 0.25 kg of golden treasure organic fertilizer starter. The starter should be mixed with rice bran (or corn flour, wheat bran) at a ratio of 1:5 to 10 before use.
2. Construction of pig manure: The prepared pig manure shall be used to carry bacteria, and the pile shall be built. The stack height and volume shall not be too short and too small. Requirements: The stack height is 1.5-2 meters, the width is 2 meters, and the length is not limited
3, adjust the moisture. The moisture content of fermented pig manure should be controlled at 40 to 65%. Judgment of moisture: The hand grips a handful of pig manure. Fingers see the watermark but not drips. Slow fermentation of water, poor water ventilation, and “spill spoilage†can lead to odors. Therefore, it is important to control the moisture content.
4, start temperature. The starting temperature should be better than 15 °C (four seasons can be operated, not affected by the season, winter as much as possible in the indoor or greenhouse fermentation), fermentation temperature control at 70-75 °C is appropriate.
5, mix and ventilate. Jinbao organic fertilizer fermentation agent needs good (consumption) oxygen fermentation, therefore, in the operation process should increase the oxygen supply measures, so that mix well, diligent turning, ventilation is appropriate. Otherwise it will lead to anaerobic fermentation and produce odor, affecting the fertilizer effect.
6, the completion of fermentation. Generally, 48 hours after the accumulation of pig manure, the temperature rises to 50-60°C, and can reach 65°C or more on the third day. It should be turned over at this high temperature. Under normal circumstances, there will be more than 65°C in the fermentation process. At high temperatures, it is possible to complete the fermentation by tipping over twice, and the fermentation can be completed within a week. The material was dark brown and the temperature began to fall to room temperature, indicating that the fermentation was completed.
