Chicken Manure Organic Fertilizer Biological Fermentation

Step 1: Mix the starter well. 1-15 tons of dry chicken manure (about 2.5-3.5 tons of fresh chicken manure) plus 1 kg of chicken manure organic fertilizer bio-starter, 5-10 kg of rice bran or corn, bran per kg of starter on average, after stirring evenly, it is withdrawn into the prepared chicken manure, and the effect is the best.
Step 2: Adjust the C/N ratio. The C/N ratio of fermented chicken manure should be kept at 25-30:1, and the acidity-basicity should be adjusted to 6-8 (ph). Because of the high C/N ratio of chicken manure, some straw, straw and mushroom residue should be added to ferment together.
Step 3: Regulate the moisture content of chicken manure. In the process of fermentation of organic fertilizer, it is very important whether the moisture content is suitable or not. It should not be too high or too low. It should be kept at 60%-65%. The method of judging is to grasp a handful of materials tightly, see the watermarks on the fingertips but not drip water, and disperse them on the ground.
Step 4: Build a pile of chicken manure. When making chicken fermentation compost, it can not be too small or too short, which will affect fermentation. The height is generally about 1.5 meters, the width is about 2 meters, and the length of the compost is more than 2-4 meters.
Step 5: Mix well and ventilate. Chicken organic fertilizer bio-starter is an oxygen-consuming microorganism, so oxygen supply measures should be increased in the process of fermentation. Large-scale farms can use organic fertilizer compost machine turning compost, so that mixing, frequent turning and aeration are appropriate, otherwise the effect of material fermentation will be affected by anaerobic fermentation.
Step 6: Fermentation is completed. Generally, after 48 hours of accumulation of chicken manure, the temperature will rise to 50-60 degrees C, and on the third day it can reach 65 degrees C or more. Under this high temperature, it will turn over once. Generally, there will be 2-3 times of high temperature above 65 degrees C in the fermentation process, and the fermentation can be completed by turning over 2-3 times. Normally, the fermentation can be completed within a week or so, so that the material can completely deodorize and ferment. Ripening, sterilization and insecticidal.
