Method for fermenting organic fertilizer with litter
2019-09-06
1. Prepare the materials. First smash the litter, 1 to 1.5 tons of litter, fresh material about 2.5 to 3.5 tons, with 1 kg of fertilizer starter. Mix the fermentation starter with rice bran (or corn flour, wheat bran) at a ratio of 1:5 to 10 for use.
2. Adjust C/N. The C/N ratio of the organic fertilizer manufacturing process should be kept at 25-30:1.
3. Control moisture. The moisture content of litter should be controlled at 60-65%. Moisture judgment: hold a hand tightly on the material, see the watermark but not dripping, and it is appropriate to land. Low water fermentation, slow water and poor ventilation, can also lead to "septic bacteria" work and produce odor. Because the C/N of leaves and hay is too low, it should be adjusted. Therefore, one ton of hay leaves should be added with one kilogram of urea (or plus 100 kilograms of livestock manure).
4. Building requirements. Stack the prepared materials while sprinkling the bacteria. The stack height and volume should not be too short or too small. Requirements: stack height 1.5 meters, width 2 meters, length 2 to 4 meters or longer.
5. Temperature requirements. The starting temperature is better than 15 °C (the four seasons can be operated, not affected by the season, and the winter is fermented indoors or in the greenhouse), and the fermentation temperature is controlled below 70-75 °C.
6. Turn over the oxygen supply. The fertilizer fermentation agent needs good (consumption) oxygen fermentation. In the organic fertilizer manufacturing process, it should increase the oxygen supply measures, so that it is better to mix well, diligently turn and ventilate. Otherwise, it will lead to anaerobic fermentation and produce odor, which will affect the effect. Here we can use the compost turning machine to turn the materials evenly and increase the fermentation effect.
7. The fermentation is completed. Generally, after 48 hours of material accumulation, the temperature rises to 50-60 ° C, and the third day can reach above 65 ° C. At this high temperature, it should be tipped over. Under normal circumstances, there will be two high temperatures above 65 ° C during the fermentation process. Fermentation can be completed by tipping over twice, and fermentation can be completed within one week. The material was dark brown and the temperature began to drop to room temperature, indicating complete fermentation.
