How many quantity mix of raw material is in an organic fertilizer?
In modern agricultural production, the use of organic fertilizer has been paid more and more attention, it can not only provide the nutrients needed by plants, but also improve the soil structure and improve soil fertility. There are a variety of raw materials for organic fertilizer, including livestock manure, crop straw, food processing waste and so on. So, in an organic fertilizer production process, how much is the amount of various raw materials? This usually depends on the characteristics of the raw material, the formulation of the organic fertilizer, and the scale of production. Here are some popular science knowledge about the amount of raw materials.
1. Selection and ratio of raw materials
The raw material selection of organic fertilizer is very important, and the commonly used raw materials include livestock manure, crop straw, food processing waste and so on. These raw materials need to be properly treated, such as fermentation, crushing and drying, to ensure the quality and effect of organic fertilizer. When determining the amount of raw materials, it is necessary to consider the nutritional content of raw materials, such as nitrogen, phosphorus, potassium, etc., as well as the carbon-nitrogen ratio of raw materials (C/N ratio), which will affect the fermentation process and fertilizer efficiency of organic fertilizers.
2. Control of fermentation process
Fermentation is a key step in the production of organic fertilizer, which involves the decomposition and conversion of organic materials. In the fermentation process of organic fertilizer, the role of Windrow Compost Turning Machine can not be underestimated. It can ensure the oxygen supply inside the compost, promote the activity of microorganisms, and accelerate the decomposition of organic matter. The quality and efficiency of compost can be improved by this mechanical turning. In the fermentation process, it is necessary to control the appropriate moisture, temperature and ventilation conditions to promote the activity of microorganisms. For example, the water content of livestock and poultry manure is usually high, and it needs to be mixed with other auxiliary materials such as straw to adjust the water content and ensure the fermentation effect. During fermentation, the amount of raw materials is reduced by evaporation of water and decomposition of organic matter.
3. Granulation and packaging
In the granulation process of organic fertilizer, the fermented raw materials need to be crushed, mixed and granulated for easy application. Granulators such as Fertilizer Granules Compaction Machine and Flat-Die Pellet Machine can effectively make raw materials into pellets. During the granulation process, the amount of raw materials is adjusted according to the required product specifications and market demand.
4. Quality standards and testing
The production of organic fertilizer needs to meet certain quality standards, such as "organic inorganic compound fertilizer" (GB/T 18877-2020) and so on. During the production process, raw materials and finished products need to be tested to ensure their nutritional content and safety. For example, the amount of nitrogen fertilizer (such as Urea, Ammonium Sulfate, Ammonium Chloride) needs to be determined based on the needs of the crop and soil test results.
Conclusion
The amount of raw materials in organic fertilizer is a complex issue that needs to be determined according to specific production conditions and market demand. Through scientific formula design, strict production control and quality testing, organic fertilizer products that meet the standards can be produced to support agricultural production. At the same time, the production and use of organic fertilizer also helps to realize the resource utilization of agricultural waste and promote the sustainable development of agriculture.
