Fermentation method of chicken manure organic fertilizer
Send Time:2023-2-12
Fresh chicken manure needs to be fully fermented before it can be used. Fermented chicken manure is a very good organic fertilizer. Parasites and their eggs, as well as some infectious bacteria, in chicken manure are inactivated and deodorized through a decomposition process. Common fermentation methods include natural fermentation and biological fermentation:
1. Natural fermentation
The fresh chicken manure is piled into a mound, the humidity is controlled between 60-65%, and then covered with agricultural film or plastic sheet. When the temperature rises to 70℃, turn over and add water, and pile up again. When the temperature drops to normal temperature and there is no odor, that is, the fermentation is completed. If the amount of chicken manure is small, you can use fresh weeds, crop straw and other fillers. A layer of grass and chicken manure is compacted and then covered with agricultural film to ferment. Turn after 7-10 days and ferment again. It can also add grass and wood ash, stir well, accumulate and ferment for 5-7 days.
2. Biological and bacterial fermentation
Add Bacillus subtilis in fresh chicken manure, stir well, can achieve rapid fermentation, generally only about 10 days to complete the fermentation. Fermentation should be carried out in rainproof greenhouse, or on the pile covered with agricultural film, to avoid rain erosion, so as not to lose fertilizer. Biological fermentation is not only short in time, but also can kill bacteria in fertilizer, with high nutrient content and long holding period.
2. Is chicken manure organic fertilizer?
1. Chicken manure is a kind of organic manure. Research shows that organic matter in chicken manure is higher than that in manure, containing medium and trace elements, beneficial bioactive bacteria and many enzymes needed by plants. After decomposition is a good organic fertilizer, suitable for grapes, watermelon, fruit trees, vegetables.
2. Organic manure, also known as farm manure, mainly comes from plants or animals, processed by biomass, animal and plant waste and plant residues, including human excrement, manure, compost, green manure, cake fertilizer, swamp fertilizer, mud fertilizer, etc.
