What problems should be paid attention to ferment sheep manure organic fertilizer?

The specific method of fermenting sheep dung is to mix the sheep dung with straw, sawdust, mushroom residue, dry soil powder, etc. in an appropriate ratio. Although it is not difficult to ferment sheep dung, you still need to pay attention to the following points:
1. When making the pile, please don’t make it too small. Too small piles will affect the fermentation. A pile with a height of between 1.5 meters and two meters, a width of 2-3 meters, and a length of more than 3 meters will have a better fermentation effect.
2. Don’t use old bran. The nutrition and ventilation of fresh rice bran is far better than that of old rice bran.

3. During the fermentation, pay attention to supply proper oxygen supply and use the organic fertilizer fermentation equipment to turn the pile. When the temperature rises to 75 ℃ or above, it should be turned over several times. The temperature is controlled at about 65 ℃, too high temperature has an impact on nutrients. The moisture content of the fermented materials should be controlled at 60-65%. Too high or too low is not conducive to fermentation. Too little water will slow fermentation. Too much water will cause poor ventilation, slow heating and produce odor.
If the moisture content is too high, you can add straw, sawdust, mushroom residue, dry soil powder, etc. Judgment method of whether the moisture is suitable or not: holding a handful of raw material tightly, you can see the watermark between the fingers but not drip, and the materials will disperse when it hits the ground.
The whole fermentation process is completed in 5-7 days. The finished organic fertilizer is fluffy, dark brown, with a slight wine aroma or earthy taste, and rich in nutrients.
