Can dog shit be used as fertilizer?

Yes, but it must be fermented. All feces contain parasites, all kinds of eggs, filariae, germs, etc., so they must be fermented and can be used when they are thoroughly rotten. Note that the flavor produced by dog shit fermentation is very strong, so you should be prepared in advance. It is best to mix with other leaves, crop straw, sawdust and kitchen residue to ferment together.

The process of fermentation and use of dog shit fertilizer:

1. Dosage. Dog shit needs a bag of Haowangnong organic fertilizer starter.

2. Dilution: add 5-10 kg rice bran (or wheat bran, cornmeal and other substitutes) to each kilogram of fermented liquid and then evenly sprinkle it into the material heap, the effect will be better. Rice bran is not rice bran. The nutrition and ventilation of fresh rice bran are much better than that of old rice bran.

3. Mix well and ventilate. The fermentation agent of Haowangnong organic fertilizer is a good (consuming) oxygen microorganism, so we should increase the measures of oxygen supply to mix well, turn frequently and aerate. Otherwise, it will lead to anaerobic fermentation and produce bad smell, affecting the effect.

4. C / N ratio. It is better to keep the ratio of Cmax N in fermentation materials at 20: 25 and adjust the PH to 6: 8.

5. Moisture. The moisture content of fermented pig manure should be controlled at 60% to 65%. Moisture judgment: grab a handful of material, see the watermark but not drip, it is appropriate to fall to the ground and disperse. Less water, slow fermentation, more water and poor ventilation, but also lead to "spoilage bacteria" work and produce bad smell.

6. Temperature. The start-up temperature should be above 15 ℃ and the fermentation temperature should be controlled below 70-75 ℃.

7. Complete. Dog shit can be fermented in 20-30 days, and sawdust takes a little longer. In the middle stage, there are a large number of white hyphae in the pile for normal fermentation, in the later stage, the temperature no longer changes, the powdered material is dark brown, straw and straw are broken, and the fermentation products are sprinkled with fragrance or soil flavor, indicating that the fermentation is complete. Fermented bio-organic fertilizer (or seedling flower nutrition soil), because it has been fully fermented and mature, it is necessary to do shallow fertilization to avoid deep application.
