The process of fermenting organic manure from sheep manure includes steps such as raw material collection, sheep manure pretreatment, mixing additives, composting, turning and drying, processing into powder, and quality testing. Here's a closer look at these steps:
1. Raw material collection.
In the process of sheep farming, sheep manure is the main waste. In order to ferment sheep manure to make organic fertilizer, a large amount of sheep manure raw materials need to be collected first. The collected sheep manure needs to be pre-treated to facilitate the fermentation process.
2. Sheep manure pretreatment.
The collected sheep manure needs to be pre-treated. The main purpose of pretreatment is to remove impurities and excess water in sheep manure and improve fermentation efficiency. The methods of pretreatment include drying, stirring, crushing, etc.
3. Mix additives.
In order to improve the effect of sheep manure fermentation, it is necessary to add some auxiliary materials, such as straw, rice husk, etc. These additives can help regulate the carbon and nitrogen ratio of sheep manure and promote the smooth fermentation process. When mixing additives, the proportions need to be controlled so as not to affect the fermentation effect.
Fourth, composting. Sheep manure pre-treated and supplemented with auxiliary materials is piled together to form a compost pile. During the composting process, microorganisms decompose the organic matter in the sheep manure, producing high temperatures and a certain amount of gas. This process requires temperature and humidity control to allow for optimal microbial activity.
5. Turning and drying.
In the composting process, it is necessary to turn the pile regularly to make the sheep manure evenly heated and promote the even fermentation process. At the same time, turning over the pile can also drain exhaust gases and excess water. Once fermentation is complete, it needs to be dried for easy storage and transportation.
6. Processing into powder.
The dried sheep manure organic fertilizer is crushed and ground and processed into powder. The processed powder can be easily mixed with other fertilizers to improve the efficiency of fertilization.
7. Quality inspection.
Samples were taken from the finished sheep manure organic fertilizer for quality testing to detect whether its nutrient content, heavy metal content and other indicators meet the relevant standards. Quality testing is an important step to ensure the safety and effectiveness of organic fertilizer.
In short, the process of fermenting organic fertilizer from sheep manure can be completed through the above seven steps. This process requires attention to the quality control of each link to ensure the quality and safety of the final product. At the same time, it is also necessary to comply with relevant laws, regulations and standards in the process of making organic fertilizer to ensure the environmental protection and sustainability of the product.
