If used properly, cow manure is a very good organic fertilizer . Generally, well-rotted cow manure will turn brown or dark brown in color, but dried cow manure is not considered well-rotted.
Does drying cow dung mean it's fully decomposed?
Sun-dried cow dung is not considered fully decomposed. Sun-dried cow dung is not necessarily fully decomposed. When used in moist soil, it will undergo secondary fermentation, potentially burning roots and seedlings. It must be fully fermented and decomposed before use.
The substances contained in dried cow manure and fermented cow manure are different. During the drying process, the substances contained in cow manure do not change, only the water content decreases. However, in fermented and fermented cow manure, some pathogens and other substances have been degraded by microorganisms, and it can be used directly on plants.
How is cow dung decomposed into organic fertilizer?
1. The process of composting cow dung into organic fertilizer is usually done through fermentation, which is a common method used in rural areas because it is simple and convenient.
2. You can first pile up the cow dung, about 70 centimeters high. Pile it into a cylinder about 70 centimeters high, as this will make it easier for it to ferment.
3. After piling the mixture, surround it with straw mats and cover the straw mats with a layer of soil. This method allows for more thorough fermentation and shortens the fermentation time.
4. After the soil has dried completely, start watering from the top. Generally, fill half a cubic meter of water with three cubic meters of cow manure. After watering, cover the top with a layer of plastic and straw mat to prevent rainwater from entering later, especially during the rainy season. If water keeps entering, it will affect the fermentation time and effect.
5. Fermentation time generally ranges from 3 to 6 months. To speed up fermentation, some fermentation agent can be added when watering the dung, which can complete fermentation within a month. In rural areas, cow dung is typically composted this year and used the following year.
6. When cow manure is composting, you can add sheep manure, duck manure, etc. to ferment together. The more types of manure, the better the fertilizer effect will be, and the more materials there are, the easier it is to ferment successfully.
