In rural areas, cow dung is a common organic fertilizer that is rich in nutrients needed by crops. However, direct application of unrotted cow manure can lead to problems such as the spread of plant pests and diseases and root burning. Therefore, it is essential to allow cow dung to rot. Here are a few simple ways to help you get your cow dung to rot quickly.
1.Natural pile rot method.
Cow dung is piled up in a covered place, such as a shed or under an open cover, and allowed to ferment naturally. This method takes a long time, generally taking 3-6 months to complete the decomposition. During this time, the cow dung pile needs to be turned regularly in order to allow oxygen to enter and promote the decomposition of microorganisms. When cow dung becomes dark in color, soft in texture, and has no peculiar smell, it means that it has been rotted.
2.Addition of microbial agents.
Adding an appropriate amount of microbial agent to cow dung can speed up the decomposition process of cow dung. The microbial agent contains a large number of microbial flora, which can promote the decomposition and transformation of cow manure. The specific use method is to mix the fungus agent with an appropriate amount of cow dung evenly, and then pile it in a well-ventilated place, which can be completed in 2-3 months.
3.Add superphosphate method.
Adding an appropriate amount of superphosphate to cow dung can speed up the decomposition process of cow dung. Superphosphate promotes microbial decomposition and mineralization, while also increasing the absorption of nutrients by plants. The specific use method is to mix superphosphate with an appropriate amount of cow dung, and then pile it in a well-ventilated place, which generally takes 2-3 months to complete the decomposition.
4.Biological fermentation method.
Cow manure is mixed evenly with an appropriate amount of crop straw and leaves, then added with water to adjust the humidity, piled into strips or loaded into a fermentation tank, and covered with a film for fermentation. During fermentation, microorganisms multiply and break down the organic matter in cow dung, making it rotten. This method generally takes 1-2 months to complete the decomposition, but the time can be greatly reduced.
Regardless of the method used, the following points need to be noted: first, cow manure must be fully fermented and decomposed before it can be applied so as not to cause harm to the plant;Secondly, in the process of stacking, it is necessary to pay attention to turning and adjusting the moisture to maintain a suitable temperature and humidityFinally, the rotted cow manure can be applied as a base fertilizer, but it should not be overapplied to avoid problems such as root burning.
In short, the easiest ways to make cow dung rot include natural composting method, adding fungi method, adding superphosphate method and biological fermentation method. In practice, you can choose the method that suits you according to the actual situation. At the same time, it is necessary to pay attention to the application of cow dung only after sufficient fermentation and decay to avoid harm to plants.
