Jinbao-type fermentation aids work effectively during the composting process by relying on the activity of functional bacteria. These microorganisms thrive best in a "carbon-to-nitrogen ratio" (C/N ratio) of 20 to 30:1, which ensures an optimal nutritional balance. To support this, it's important to carefully adjust the material proportions to meet this ideal range. If the C/N ratio is too low, it can lead to nutrient deficiency, which may hinder the fermentation process.
For example, if the fermentation material consists solely of animal manure, the C/N ratio is typically below 20, meaning you should add some high-carbon materials like straw or sawdust to balance it out. In practice, many farms either intentionally or unintentionally mix in small amounts of sawdust or fiber-rich materials into the bedding or feed. This can naturally increase the carbon content, resulting in a C/N ratio close to 30:1. This is often referred to as "balancing" the mixture. Therefore, under normal conditions—such as when moisture levels are appropriate—chicken manure with some impurities doesn’t necessarily require additional additives for proper fermentation.
When using materials like straw, wood chips, peanut shells, or rice husks—which are high in crude fiber—it’s usually necessary to add nitrogen-rich substances such as urea solution, chicken manure, or fecal water to help achieve a balanced C/N ratio. For more accurate calculations, you can refer to specialized resources like the company’s guide on "Carbon-Nitrogen Ratio Calculation Methods."
Additionally, the texture and particle size of the materials matter. Straw and similar materials should generally be chopped or crushed and mixed thoroughly to ensure even distribution. If the final product is intended for sale, attention should be given to the appearance of the finished compost, so finer grinding is recommended. However, if the compost is for personal use, the requirements for material fineness can be more flexible.
By carefully managing these factors, you can significantly improve the efficiency and quality of the fermentation process, leading to better results in compost production.
