Compost is a type of organic fertilizer rich in nutrients, offering long-lasting and stable fertility. It also aids in the formation of soil granular structure, enhancing the soil's ability to retain water, heat, and air, as well as nutrients. Moreover, when mixed with fertilizers, it can compensate for their deficiencies.FertilizerNutrient content is singular, long-term use of the fertilizer aloneMaterialSoil compaction, reduced water and nutrient retention. Among them, aerobic composting is a process where aerobic bacteria absorb, oxidize, and decompose waste under good aeration and sufficient oxygen conditions. Aerobic microorganisms oxidize a portion of the absorbed organic matter into simple inorganic substances through their life activities, releasing energy required for microbial growth and activity. Meanwhile, the other organic matter is synthesized into new cell material, allowing microorganisms to continuously grow and reproduce, producing more biomass. Typically, aerobic composting has higher temperatures, preferably around 55-60°C, hence it is also known as high-temperature composting. High-temperature composting can kill pathogens more effectively, degrades organic matter quickly, requires fewer days for composting, produces less odor, and is a necessary condition for composting.
Utilizing animal and poultry feces aligns with China's 11th Five-Year Plan's proposed economic growth model, which emphasizes resource utilization as the core, "reduction, reuse, and resourcefulness" as the principle, and low consumption and low emissions as basic characteristics. This model is in line with the concept of sustainable development, aiming to build a resource-saving and environmentally friendly society through resource utilization.
Poultry and livestock manure is a valuable fertilizer resource. Through processing, it can be made into organic compound fertilizer, thereby increasing the source of biological organic fertilizer and reducing...FertilizerApplication of organic fertilizers helps improve soil structure, enhance the quality of fruits, vegetables, and crops, and serves as a fertilizer for producing green, non-toxic food products. As a major agricultural country, China has, for many years, excessively used chemical fertilizers, resulting in a lack of organic fertilizers and imbalanced nutrient ratios. This has led to varying degrees of damage to the farmland ecological environment, soil physical and chemical properties, and microbial communities, which in turn has somewhat affected the quality of agricultural products.FertilizerThe long-term use has led to drawbacks such as reduced fertilizer effectiveness, low utilization rates, and soil compaction; biological fertilizers are the follow-up solution.FertilizerThe next fertilizer revolution. Applying bio-organic fertilizers can improve soil quality, reduce costs, and enhance crop yield and quality. Fertilizers are a high-energy-consuming product, but producing bio-organic fertilizers from animal and poultry waste has low energy consumption and makes full use of resources, turning waste into treasure. With the development of China's agriculture towards green, organic, and ecological agriculture, and the growing desire and demand for green organic food, the proportion of bio-organic fertilizers in the fertilizer market will gradually increase.

As the modernization level of agriculture increases, organic foods have gained more attention from people. Consequently, ecological agriculture has also become a focus, as only ecological agriculture can produce ecological foods. In this regard, the country has invested heavily in support, both in terms of policy support and actual actions. The widespread use of organic fertilizers that we are aware of now is a good illustration. It can be said that organic fertilizers will gradually replace other fertilizers and become an essential fertilizer for crop growth. Organic fertilizers refer to a type of fertilizer containing organic matter, which can provide crops with various inorganic and organic nutrients while also improving soil fertility. Most of them are made locally by farmers, but traditional homemade organic fertilizers have issues such as uneven fermentation, the production of smelly waste gases during fermentation, environmental pollution, and often uneven internal temperatures due to structural and design limitations.


Farmyard manure, such as animal feces, makes excellent fertilizer. It's rich in nutrients for crop planting and free from chemical components. For instance, chicken manure is particularly noteworthy due to its high nutrient content, including nitrogen, phosphorus, potassium, and other trace elements, all in a balanced proportion. Moreover, the concentration of these elements in chicken manure is several times higher than that in cow manure. For chicken farmers, dealing with feces is a headache, especially as the country tightens its environmental protection regulations. If these feces can be recycled for fertilization, it truly transforms waste into treasure. However, spreading feces directly on fields without treatment poses many hazards, such as pests and diseases, crop scorching, toxic gas production, and slow fermentation. Therefore, farmyard manure must be fermented before use, requiring a sealed, constant-temperature fermentation environment to enhance efficiency and quality.
China is a major agricultural country, and the development of agriculture is inseparable from fertilizers. With the increasing pursuit of high yields in planting, the demand for fertilizers in China is growing rapidly. As is well-known, the fertilizers currently used in China's agricultural production are mainly chemical fertilizers, which have the advantages of easy scalability, convenient transportation and application, and increased crop yields. However, the long-term improper use of chemical fertilizers has led to problems such as soil compaction, decreased soil fertility, ecological damage, environmental pollution, and a decline in the quality of agricultural and sideline products, which have received high attention from relevant national departments and the agricultural science and technology community. China is also a populous country and is currently in a period of rapid urbanization. If the waste from urban populations is not utilized, it can become a significant source of pollution; however, if used properly, it can be a sustainable resource. Currently, people have used domestic waste to produce some organic fertilizers, and have achieved certain results. In China, the total annual output of straw is about 800-1,000 million tons, especially in the north, where corn and reed resources are abundant, widely distributed, and concentrated. The amount of straw produced increases year by year with the increase in grain yield per unit area and total output. However, the corresponding treatment technology lags behind, leading to a series of environmental and social issues, such as air pollution, fires, and eutrophication of water bodies.
