Chicken manure is a high-quality organic fertilizer, rich in nitrogen, phosphorus, potassium and other nutrients, which has a good effect on improving soil structure and soil fertility. However, chicken manure contains a large amount of harmful substances such as germs, insect eggs, and weed seeds, which must be fermented to be safe to use. So, how to ferment chicken manure organic fertilizer? Let's take a look at it.
1. Prepare materials.
1.Fresh chicken manure: Chicken manure without pesticide residues and heavy metal contamination is required.
2.Organic materials: organic materials such as straw, wheat straw, and wood chips can increase the air permeability and moisture content of chicken manure, and can also be used as nutrients for fermentation bacteria.
3.Fermentation bacteria: Commonly used fermentation bacteria include eminent bacteria, yeasts, etc., which can be purchased from the market or homemade.
4.Regulators: In order to improve the taste of chicken manure and promote fermentation, regulators can be added in moderation, such as molasses, starch, etc.
Second, the treatment method.
1.Mix fresh chicken manure with organic materials in a certain proportion, generally chicken manure accounts for about 60%, and organic materials account for about 40%.
2.Add water to the mixed material and stir evenly, the moisture content is controlled between 50%-60%, and the judgment standard is to hold the material tightly by hand, and there are water droplets between the fingers but not dripping.
3.Add an appropriate amount of fermentation bacteria and conditioner to the stirred material, and then pile it into a strip pile about 1 meter high and 2 meters wide, and cover it with plastic sheeting or grass curtain to maintain humidity and temperature.
4.After a few days, turn the ingredients once a day to allow for a more even fermentation. The general fermentation time is about 15 days, and it can take about a month in winter.
5.The fermented chicken manure organic fertilizer is black-brown in color, has a strong wine flavor, and has no peculiar smell. If the fermentation is not complete, there will be a pungent smell.
3. Precautions.
1.During the fermentation process, attention should be paid to controlling the temperature and humidity, too high temperature will lead to seedling burning, and too low will affect the fermentation effect.
2.Fermented chicken manure organic fertilizer can be used as basal fertilizer, top dressing or foliar fertilizer, but avoid direct contact with seeds and roots so as not to affect germination and growth.
3.Although chicken manure organic fertilizer is rich in nutrients, it should not be used excessively, so as not to cause problems such as seedling burning and salt accumulation. It is recommended to use it in moderation according to soil fertility and crop growth.
4.Chicken manure with heavy metals and antibiotic residues needs to be treated before use to avoid harm to the environment and crops.
Through the above steps, you can easily ferment high-quality chicken manure organic fertilizer. This fertilizer can not only improve the yield and quality of crops, but also improve soil structure and increase soil fertility, providing strong support for the development of green agriculture.
