Composting fertilizer
Compost is an organic fertilizer produced through the biodegradation process of natural organic matter, such as plant residues, animal manure, kitchen waste, etc. The composting process is a biochemical decomposition process under the action of microorganisms, in which organic matter is gradually converted into a soil-like dark brown substance called humus under aerobic conditions. Compost is rich in nutrients and is an environmentally friendly and sustainable soil conditioner.

Compost Fertilizer Detailed Introduction
Compost fertilizer is a fertilizer produced by the natural decomposition and transformation of organic matter. As an important organic fertilizer, compost is widely used in agricultural production. It can not only effectively improve soil fertility, but also improve soil structure and promote the healthy growth of crops. With the development of agricultural sustainability, compost fertilizer has received more and more attention. This article will introduce the concept, production process, types, usage methods and advantages of compost fertilizer in agriculture in detail.
The concept of compost fertilizer
Compost fertilizer is an organic fertilizer formed by the natural degradation of organic matter (such as plant residues, animal feces, kitchen waste, etc.) under the action of microorganisms. The composting process usually occurs under aerobic conditions, and microorganisms decompose organic matter into more stable humus to form fertilizer with a higher nutrient content. Compost fertilizer not only contains rich basic nutrients such as nitrogen, phosphorus, and potassium, but also contains a variety of trace elements and organic matter, which plays an important role in soil health.
The production process of compost fertilizer
Raw material selection
The production of compost fertilizer begins with the selection of raw materials. Common compost raw materials include:
High carbon materials: such as straw, dead leaves, branches, etc. Such materials usually have high carbon content but low nitrogen content, which helps to form the compost structure.
High nitrogen materials: such as animal manure, green plant residues, kitchen waste, etc. These materials have high nitrogen content and can provide nitrogen sources required for microbial decomposition.
Mixing and stacking
Different types of raw materials are mixed in a certain proportion to maintain an appropriate carbon-nitrogen ratio (C/N). Generally, the ideal carbon-nitrogen ratio is between 25:1 and 30:1. The mixed materials are stacked into piles. The size of the pile depends on the scale of the compost, but it should generally ensure that the pile has enough volume to maintain heat while being fully ventilated.
Ventilation and humidity control
During the composting process, oxygen and humidity are key factors affecting microbial activity. By regularly turning the pile or using mechanical equipment (such as a turner), it is possible to ensure that there is sufficient oxygen supply in the pile to promote the activity of aerobic microorganisms. In addition, the humidity of the composting material should be maintained between 40% and 60%. Too high humidity will lead to anaerobic fermentation and produce odor; too low humidity will inhibit the activity of microorganisms and delay the composting process.
Temperature management
During the composting process, temperature is an indicator of microbial decomposition activity. The temperature of composting is usually divided into three stages:
Heating stage: Microbial activity is enhanced, and the temperature of the pile rises rapidly, usually reaching 40-60℃.
High temperature stage: The temperature of the pile is stable between 55-65℃, effectively killing pathogens and weed seeds.
Cooling stage: As the easily decomposable substances decrease, the temperature of the pile gradually decreases, and the compost gradually matures.
Maturation and screening
After several months of decomposition, the compost gradually transforms into a dark brown, loose, odorless humus, that is, mature compost. Mature compost usually needs to be screened to remove larger particles that are not completely decomposed, and then it can be used for agricultural production.
How to use compost fertilizer
Base fertilizer use
Compost fertilizer is usually applied as base fertilizer before crop planting and mixed into the soil by deep plowing. The amount of base fertilizer applied should be adjusted according to soil conditions and crop needs, usually 15-30 tons per hectare.
Topdressing use
Compost fertilizer can also be applied as topdressing during crop growth, especially for high fertilizer-demanding crops such as fruit trees and vegetables. When applying topdressing, attention should be paid to the location of fertilizer application to avoid direct contact with crop roots to avoid fertilizer damage.
Soil improvement
Compost fertilizer can also be used for soil improvement, especially for improving poor or sandy soil. By increasing the content of soil organic matter, compost can improve soil water retention and air permeability and improve soil structure.
Advantages of compost fertilizer
Improve soil fertility
Compost fertilizer contains rich organic matter and nutrients, which can improve soil fertility and promote crop growth. At the same time, the humus contained in compost can increase the aggregate structure of the soil and improve the air permeability and water retention of the soil.
Enhance soil biological activity
Organic matter and microorganisms in compost can enhance the biological activity in the soil, promote the reproduction of beneficial microorganisms in the soil, inhibit the growth of pathogens, and improve the soil ecosystem.
Environmentally friendly
Compost fertilizer is a sustainable agricultural fertilizer. By using organic waste to make compost, it can reduce the amount of landfill and reduce environmental pollution. In addition, compost fertilizer can reduce the use of chemical fertilizers and reduce the risk of chemical fertilizer pollution to soil and water bodies.
Promote circular agriculture
The production and use of compost fertilizer is in line with the concept of circular agriculture. By converting agricultural waste into valuable fertilizers, a closed-loop agricultural production system is formed, which contributes to the sustainable development of agriculture.
Conclusion
As an important organic fertilizer, compost fertilizer has a wide range of application prospects in agricultural production. It can not only effectively improve soil fertility and improve soil structure, but also promote the healthy growth of crops and reduce environmental pollution. With the advancement of sustainable agricultural development, the production and application of compost fertilizer will continue to be promoted, providing a solid foundation for modern agriculture.

Application of composting fertilizer equipment turner and its influence on composting efficiency
As a key equipment in the composting production process, compost turning machine can effectively improve the decomposition speed and quality of compost. This study explored the role of compost turning machine in compost fertilizer production and analyzed its influence on temperature, humidity, oxygen supply and organic matter decomposition efficiency during composting. The study showed that the rational use of compost turning machine can not only shorten the composting cycle, but also improve the nutritional content and stability of compost, providing strong support for the sustainable development of modern agriculture.
Composting machine in compost fertilizer production
Working principle of composting machine
Composting machine is a mechanical equipment specially used for compost turning and aeration. It mainly turns the compost material regularly through mechanical devices to make the material fully mixed and increase the oxygen content in the pile. The main functions of composting machine include:
Mixed materials: fully mix organic waste from different sources to ensure uniform distribution of materials, which is conducive to the balanced decomposition of microorganisms.
Increase ventilation: through turning, increase the oxygen content in the compost, promote the activity of aerobic microorganisms, and accelerate the degradation of organic matter.
Adjust humidity: The humidity of the compost can be adjusted during the turning process to avoid local over-wetting or over-drying and improve the uniformity of the compost.
Classification of turners
Based on the different structures and functions, turners can be divided into different types:
- Hydraulic Compost Turner: The hydraulic compost turner is the professional machine for horse manure compost and other organic materials fermentation. It adopts advanced hydraulic operating system, pull rod power steering operation and crawler-type running mechanism.
- Wheel Type Compost Turner: The wheel type compost turner is suitable for fermentation and turning of organic wastes such as large-span and high-depth livestock and poultry manure, sludge garbage, sugar mill filter sludge, slag cakes and straw sawdust. It is widely used in organic fertilizer plants , compound fertilizer plant, sludge garbage plant, garden field and Agaricus bisporus plantation, etc..
- Groove Type Compost Turner: This organic fertilizer compost turner, which includes groove type compost turner and groove type hydraulic compost turner, is the most widely-used aerobic fermentation machine and compost turning equipment.
Effect of composting machine on composting process
Effect on temperature
Temperature is an important factor affecting microbial activity during composting. By turning the materials, the composting machine can evenly distribute the heat in the pile and prevent local overheating or overcooling. Experiments show that regular use of composting machine can keep the compost temperature within the appropriate range of 50-65℃, effectively promote the killing of pathogens and weed seeds, and accelerate the decomposition of organic matter.
Effect on oxygen supply
The composting process is an aerobic biological decomposition process, and oxygen supply is the key. The composting machine can destroy the compaction layer in the material, increase the porosity inside the pile, and improve the oxygen permeability through mechanical turning, thereby providing sufficient oxygen support for aerobic microorganisms. Adequate oxygen supply not only accelerates the degradation of organic matter, but also reduces the odor generated by anaerobic fermentation and improves the environmental quality of the composting site.
Effect on humidity
The moisture content of composting materials has an important influence on microbial activity and composting process. The composting machine can evenly distribute the moisture in the material during the turning process to avoid local water accumulation or drying. Appropriate humidity (40%-60%) helps maintain the activity of microorganisms and ensures the smooth progress of the composting process.
Impact on the decomposition efficiency of organic matter
Through effective mixing and ventilation, the composting machine can significantly improve the decomposition efficiency of organic matter. Experimental data show that the decomposition rate of composting materials using the composting machine is 30%-50% higher than that of traditional static fermentation. In addition, the composting machine can also reduce the loss of carbon and nitrogen in the composting process and improve the fertilizer efficiency of the compost.
Economic and environmental benefits of composting machines
The use of composting machines can significantly shorten the composting cycle and increase the yield and quality of compost. For large-scale agricultural producers, the improvement of composting production efficiency can reduce dependence on chemical fertilizers, reduce production costs, and at the same time increase crop yield and quality, thereby achieving higher economic benefits.
By optimizing the composting process, composting machines can help reduce the emission and treatment costs of organic waste and reduce environmental pollution. At the same time, the promotion and use of compost fertilizers can improve soil health, reduce the use of chemical fertilizers, and help achieve the sustainable development goals of agriculture.
Conclusion
As a key equipment in composting production, composting machines have a significant effect on improving composting efficiency and quality. The rational use of composting machines can not only accelerate the decomposition of organic matter and shorten the composting cycle, but also improve the stability and nutritional value of compost products. In the future, with the further development of agricultural mechanization and intelligence, the functions and performance of composting machines will be further optimized, providing strong support for the widespread application of compost fertilizers.
