Organic fertilizer manufacturing process refer to commercial organic fertilizers that do not contain specific fertilizer effects and are processed and deodorized by high-temperature treatment using livestock waste, straw, agricultural by-products and solid waste processed in food processing, organic waste, and urban sludge. It has the advantages of improving the efficiency of farm soil to improve fertilizer efficiency, but also has its own characteristics:

1.High organic matter content, generally greater than 30%, and some as high as 60%.

2.The harmless standard is high, and the refined organic fertilizer has undergone 4-5 days of high temperature treatment during the production process, which can effectively kill the pathogenic microorganisms, pests and weed seeds in the raw materials, making the fertilizer hygienic standard significantly better than farm fertilizer To meet the standards issued by the Ministry.

3.Low cost, refined organic fertilizer raw materials mostly use agricultural wastes and by-products, with a wide range of sources, usually using simple high-temperature rapid processing technology to evaporate a large amount of water in the raw materials, rapid deodorization, rapid dehydration, low energy consumption, production The cost is low and economical.

4.Refined organic fertilizers mainly provide organic matter and a small amount of nutrients, which has the advantage of rich organic matter. However, due to the low nutrient content (about 6%), it usually can not meet the needs of crop growth. Generally, it needs to be used in conjunction with inorganic fertilizers.

In the organic fertilizers manufacturing process, how to granulate the raw materials after fermentation is a key factor that determines whether commercial fertilizers can enter the market and circulate. Generally, the following granulation methods are adopted.

(1) Agglomeration granulation. It is under the action of rotation, vibration, stirring, etc. to make the wet powder in motion agglomerate. Or use fluidized bed to make dry powder and granules get cohesion by supplying spray liquid (adhesive) to grow into proper granules.
 

(2) Extrusion granulation. It is a method that uses mechanical processing such as extrusion, roller extrusion or pressing to make dry powder or wet powder containing binder into a cylindrical, spherical or tablet shape.
 

(3) Crushing granulation. It is to crush massive materials into granules of appropriate size.
 

(4) Melt granulation. It is a method of granulation by cooling and hardening molten liquid.
 

(5) Spray granulation. It is a method of directly granulating solids in liquid after concentration.
 

(6) Crystallization and granulation method in the liquid phase. It is a method of agglomerating into spherical particles by liquid bridging agent and stirring while the materials are crystallized in the liquid phase.

This technology is widely used in the pharmaceutical industry. Because the shape of the particles is spherical, it is also called the spherical crystallization granulation method, referred to as the spherulite granulation method. The spherulite granules are pure material particles, which have good fluidity, filling property and compression moldability. In recent years, the technology has been successfully prepared. That is, in the process of spherulite crystals, polymer copolymer precipitation is added to prepare slow-release, quick-release, enteric, stomach-soluble pellets, floating hollow pellets, biodegradable microcapsules, etc. Recently, it has been successfully applied to the preparation of sustained-release pellets.

Measures to improve composting technology and quality of compost

Although the application of garbage compost can improve the soil and promote plant production, due to the composition of the garbage itself, the process is more professional in the fertilizer manufacturing process , which will also have a potential impact on the environment. The high cost of production, transportation and application, and poor economic benefits, restrict the application and development of compost. However, as a method of waste treatment and resource recovery, economic efficiency cannot be the only criterion for measuring, but to make it a promising method of garbage treatment, improving the composting process and improving the quality of composting are the main directions for future development.

Improvement of composting process

There is a long history of composting, and there are many technical processes. The treatment cost, treatment effect and compost quality of different process methods are different. Traditional anaerobic composting uses anaerobic microorganisms to complete the decomposition reaction. Air and compost are isolated, the temperature is low, the process is relatively simple, the nitrogen storage in the product is relatively large, but the composting cycle is too long, the odor is strong, and the decomposition is not Full substance. The modern composting process is basically aerobic composting through forced ventilation.This is because aerobic composting has a high temperature and effectively kills pathogenic bacteria.The matrix is completely decomposed, the composting cycle is short, and the odor is small. Etc.

How to sort and collect garbage, which sorting equipment is needed?

Composting is a treatment technology for organic components in garbage. The wastes such as Shikuai, metal, and glass not only affect the fermentation process of compost, but also affect the quality of compost. These substances must be sorted out and treated separately. At present, China’s urban domestic waste generally adopts a mixed collection method. Although the paper, plastic, etc. in the garbage are greatly reduced after multiple pick-ups by residents, scavengers, sanitation workers, etc., the garbage still contains some non-degradable substances such as metals and waste batteries , Waste lamps, etc. At present, in the process of composting, the method of mechanical combined with manual sorting is usually adopted. The mechanical sorting methods mainly include screening, wind sorting and magnetic sorting. Taking effective measures to promote the separation and collection of municipal solid waste in China is very necessary to save the cost of compost and improve the quality of compost.

Screening and cultivation of microorganisms, how to shorten the compost maturity cycle

Composting mainly uses microorganisms to degrade organic matter, and microorganisms are the main body of the composting process. The types and number of microorganisms in compost have an important influence on the fermentation time and fertilizer efficiency of compost. There are two main sources of microorganisms in composting. On the one hand, it comes from the composting material itself. On the other hand, special microorganisms are acclimated and cultivated to inoculate compost. These strains have the characteristics of strong activity, fast reproduction, and rapid decomposition of organic matter. They can accelerate the process of compost reaction, shorten the compost reaction time, and help reduce investment and land occupation.

In China’s agricultural production, in order to increase the yield of crops, people will not hesitate to dump a large amount of chemical fertilizers (inorganic chemical fertilizers) into the farmland, and the use of nitrogen fertilizer, urea, and compound fertilizer composed of nitrogen, phosphorus, and potassium is increasing, and the concentration The higher. Although this has maintained a certain effect of increasing output, year after year, the consequences are extremely serious, the main performance is as follows:

So what the benefits of the organic fertilizer manufacturing process are?

First, the soil is compacted and solid, resulting in poor soil porosity and decreasing organic matter content, which has caused many biological groups to lose space for survival in the soil and ultimately reduced soil fertility.

Second, due to soil compaction, the soil’s water storage capacity is decreasing, and the lack of groundwater has seriously affected agricultural production.

Third, due to the soil compaction, the biological population is reduced, and the farmers ’friends are striving to increase the yield of the land, so that the amount and concentration of chemical fertilizers continue to increase, resulting in the decreasing utilization of nitrogen, phosphorus, and potassium, only reaching 30% to 40% According to the calculation of the consumption, the loss will reach 30 billion to 40 billion yuan.

Fourth, in addition to wasting losses, a large amount of chemical fertilizers remaining in the soil continue to penetrate deep underground to form a large amount of nitrate and other compounds, causing serious pollution of groundwater, and on the other hand, it is released into the atmosphere as nitrogen oxides, making The ozone layer becomes thinner, causing ultraviolet light to affect human health and the growth of crops, and the ecological environment is severely affected.

Fifth, the use of large amounts of chemical fertilizers has reduced the quality and nutritional value of various crops. Take trace elements as an example. For half a century, the content of trace elements in some crops has dropped by about 20%, and the commodity rate of crops has declined, which seriously affects the interests of farmers and consumers and the export of crops.

In short, agricultural production cannot be at the expense of resources and the environment. It must combine high yield with high quality, low consumption with ecological security, and take the road of sustainable development of agricultural production. Otherwise, for such a long period of time, the natural ecology will be seriously unbalanced, and it will be the human beings that are damaged, and the consequences will be very serious. The use of scientific methods and the combination of organic and inorganic fertilizers to produce and process organic fertilizers using animal manure as raw materials, and nitrogen, phosphorus and potassium as auxiliary fertilizers is one of the most correct ways for modern agriculture.

The agricultural machinery market has great potential for development, and of course is full of various competitions and challenges. When faced with such a realistic living environment, organic fertilizer manufacturing process has not been intimidated by the difficulties in front of it, but has embraced A positive and optimistic attitude to face everything. In fact, whether it is organic fertilizer granulator machine or others, we will encounter some difficulties during the growth process. These are inevitable and cannot be avoided. Therefore, organic fertilizer equipment is in Faced with these situations, I did not choose to escape, but faced it positively, and saw it as a test of myself, a powerful motivation to promote myself to success.

Organic fertilizer equipment uses its own strength as a weapon against market competition. When facing problems, it will use its own strength to solve the problem and help organic fertilizer equipment become stronger. This shows the importance of strength for organic fertilizer equipment. After a long-term development of organic fertilizer equipment, we have accumulated rich experience and have a deeper and clearer understanding of the market development trend. During the long and arduous growth process, we continue to learn the current international The most selected technology on the market to meet market demand, provide the market with the most satisfactory organic fertilizer as a development goal, and constantly transform organic fertilizer equipment.

After long-term efforts, the organic fertilizer equipment has won the approval of a large number of users with good equipment and high technical level. Organic fertilizer equipment is not only a leader in technology, but the overall quality of the equipment is also quite reliable. In the process of practical application, it can exert its greatest ability, help users create greater economic value, and help the prosperity of society. 

The organic fertilizer manufacturing process firstly needs to go through the rot process of chicken manure, and then add the appropriate biological functional bacteria agent to be processed into biological organic fertilizer.

一. Production process

1. Material preparation: main material: chicken manure and fertilizer thoroughly decomposed after one fermentation; functional fermentation fungus.

2. Site selection: select a leeward and flat terrain for operation.

二. Operation requirements

1. The size of the fermentation pile is: 0.8-1 meters high, 2.0 meters wide, unlimited length.

2. The water content of the fermentation reactor is 55-65%, and the moisture loss of the fermented fertilizer in one fermentation needs to be added.

3. The average temperature in the pile is lower than 55 degrees, fermentation for 7 days, if the temperature is too high, turn the pile or spread it evenly. The temperature drops to about 30 degrees, spread out, and dry naturally.

三. Specific operation

1. Fertilizer once fermented adjusts moisture to about 60%.

2. Add the bacteria uniformly and stir the fermented fertilizer at one time, pile up naturally, don’t use a shovel to pat it. In case of rain, cover with plastic film.

3. The use amount of the secondary fermentation functional bacterial agent is 5 ‰ (that is, the added amount per ton is 5 kg).

At this time, whether the organic chicken manure is completely rotted, whether it is made into powdered organic fertilizer with simple equipment or granulated with an organic fertilizer granulator machine, the finished product can be sold.

Different kinds of microorganisms are involved in the fermentation process of plant residues in the organic fertilizer manufacturing process. Due to the changes in the raw materials and fermentation conditions of different plant residues, the number of various microorganisms is also constantly changing, so no microorganisms always dominate the plant residue fermentation process, and each environment has its own specific microorganism population. The main types of microorganisms involved in the fermentation process of plant residues are bacteria,

1) Bacteria During the aerobic fermentation process, there are a large number of bacteria. With a large specific surface area, bacteria can quickly absorb soluble substances in plant residues, allowing them to grow rapidly. In the early stage of fermentation, the temperature is low, mainly mesophilic bacteria. As the temperature of the fermentation reactor increases, mesophilic bacteria gradually decrease, and some Bacillus become the main body of bacteria.

2) Actinomycetes Actinomycetes are multi-cell hyphae bacteria that can decompose cellulose, hemicellulose, lignin, etc. They do not have the ability of fungi to decompose cellulose, hemicellulose, and lignin, but they are more resistant to high temperature and high pH than fungi. Therefore, they are the predominant flora degrading cellulose, hemicellulose, and lignin during the high temperature period of fermentation.

3) Fungi. Fungi are of great significance to the fermentation and maturation of plant residues. The mesophilic fungus Geotrichum and the thermophilic fungus Aspergillus fumigatus are the dominant bacterial groups in the fermentation process. Temperature is one of the most important factors affecting the growth of fungi. Most fungi are mesophilic fungi, which exist in the environment of 5 ~ 37 ℃. When the temperature rises to 64 ℃, almost all fungi disappear. When the temperature drops to 60 ℃ in the late fermentation period, mesophilic and thermophilic fungi will appear again.

In short, in the fermentation process of plant residues mainly rely on the role of microorganisms, microorganisms are the main body of fermentation, its source is the natural world, the second is artificial inoculation. In the fermentation process, high temperature will kill pathogens, eggs and weed seeds in plant residues.

Current status of organic fertilizer manufacturing process abroad

The treatment of poultry manure in developed countries is usually towards industrialization, harmlessness, recycling, commercialization, compounding with large amounts of plant nutrients, crop specialization, multiple use and efficiency, simultaneous solid-liquid treatment, industrial technology,  biological treatment, and equal emphasis in the technology development. The development principle of livestock and poultry breeding is, first of all, beneficial to the use and treatment of manure. The breeding industry is mostly in the form of small and medium-sized individual farms, and the construction and design of livestock and poultry houses are conducive to the treatment of livestock and poultry manure and urine. To reduce the dilution of water to feces, which is beneficial to reduce the energy consumption in the process of manure water treatment. According to the water content of livestock and poultry manure, the treatment methods are mainly divided into dry manure removal and water flushing.

1. Dry cleaning method

(1) Compost. Use the scraping board and conveyor belt to store the feces in the empty mine site, and use them after piled. The United States and Russia use bedding grass or peat washer to transport the manure mixed with bedding to the compost yard at intervals, and use it after composting. This tradition also exists in the vast rural areas of our country. The advantage of this method is that the animal urine is absorbed by the litter, which avoids the loss of nutrients, but the loss rate of nitrogen volatilization through ammonia is relatively large, which can reach 30% to 50% of the total nitrogen. In order to avoid losses, the United States adopts high cages for raising chickens, accumulating chicken manure under the cages, covering them with straw or peat every day, and cleaning them every six months. In the United States, there is a compost production system called BIOTEC120, which was developed by Dr. Arrau after 20 years of research. It was awarded a US patent in June 1993 and was approved by the United Nations International Environmental Protection Organization. The system is composed of 10 large-scale rotating bioreactors. Through microbial fermentation, 1300 tons of feces or garbage can be processed into high-quality organic fertilizer within 72 hours. But the processing cost is expensive, and it has not been widely applied. If it can be fermented without rotation, the processing cost may be reduced.

(2) Biogas fermentation treatment. Through biogas fermentation, the odor of feces can be effectively removed. The biogas produced at the same time can be used for life and life.

Production, can achieve clean processing and renewable energy. Moreover, the biogas slurry after biogas fermentation can produce liquid fertilizer, and the biogas residue can also continue to ferment to produce organic fertilizer.

(3) Animal transformation. Through the conversion of earthworms and fly maggots into protein feed, the rest can continue to ferment to produce organic fertilizer, but this method of use is slow and the amount of processing is not much.

2. Water cleaning method

The water flushing dung is from the livestock and poultry pen. Many countries in Europe and the United States put the cleaned manure into the storage tank, and apply the liquid directly to the soil after anaerobic fermentation or biogas fermentation. The advantage is that the processing rate and utilization rate are high, but if it is transported to the field by car, the cost is not low. Even if there is a pipeline directly input into the field, it can only reduce the operating cost, and its initial investment is also high. Some countries also add some chemical fertilizers, pesticides, herbicides, etc. to these fermented liquids to produce organic and inorganic multifunctional liquid compound fertilizers. In Japan, the solid-liquid separation method is mostly used. The separated manure is used as an organic fertilizer after rot, and the separated liquid part is used to remove the particulate part in the liquid with sand and soil filter bed, or the acidification pool method is used to promote the decomposition of organic matter. The developed countries have attached great importance to the odor of livestock and poultry manure. Most of them use physical adsorption and chemical substances to deodorize. The aeration fermentation method in Japan is very effective. After 20 h at 20-40 ℃, the odor can be all eliminate. South Korea adopts trough fermentation and oil pressure rotary agitation, which is a more advanced fecal fermentation technology in the world.

Some countries in Germany and Eastern Europe treat livestock and poultry manure water through pipelines into urban sewage treatment systems for unified treatment. In general, some advanced facilities have too high operating costs and are not widely used even in developed countries in Europe and the United States. They mainly combine traditional composting methods with artificially inserted microorganisms with strong fermentation capabilities. 

3. Treatment method of crop straw

The cropping system in Europe and the United States is different from that in China. Most of them are the annual cropping and fallow rotation system. During harvesting, a straw crusher is hung behind the combine harvester to directly return the crops to the field, or to implement no-tillage and mulch farmland. There are also farms that use straw silage or fermentation as feed to form animal manure and enter the manure fermentation process to produce an organic fertilizer system. In Europe and the United States, straw is rarely used directly to produce organic fertilizer industrially.

What are the common compost fermentation equipment and what is the specific role in the fermentation process

Composting process, also known as fermentation process, refers to the degradation and stabilization of organic waste under the proper water content, oxygen concentration and other conditions through the action of microorganisms, so as to achieve the purpose of killing parasitic eggs and harmful microorganisms, reducing volatile substances in waste, and at the same time making the organic matter loose for safe treatment and preservation. Because the materials processed by compost fermentation do not contain pathogenic bacteria and weed seeds, they are suitable for application in soil to improve soil conditions.

Composting fermentation process generally includes fermentation, composting, aeration and other links. The equipment used in these links varies with the type of compost. Stack-type composting is to agitate the material by riding the tipper on the stack, thus playing the role of aeration to achieve the purpose of fermentation. Therefore, the device configuration is relatively simple and the function is single. The tank type aerobic fermentation has a distribution system, a tipping system, an aeration system, etc. The equipment is relatively complete, including: distribution truck, organic fertilizer composter, mobile crane, an aeration system, etc. Let’s introduce the functions of these equipment in the fermentation process.

1、 Organic fertilizer composter. In order to meet the requirements of moisture, acidity and alkalinity in material fermentation, some microbial fermenters need to be added. The tipping machine can give full play to its mixing function, so that the mixing operation can achieve the purpose of uniform mixing, stirring and removing the bottom. It can also improve the permeability of raw materials, make the raw materials become fluffy and elastic, absorb a lot of air at the same time, and raise the temperature of the fertilizer pile. If the temperature is too high, it can also absorb fresh air, so that the temperature can be reduced again, In this way, the alternating state of medium and high temperature is formed, which is beneficial to the growth and reproduction of microorganisms.

2、 Cloth truck. The function of the distributor truck is to evenly distribute the materials in the fermentation tank, so that the forklift does not have to enter and leave the fermentation tank frequently, reduce the cost of raw material transfer, and improve the work efficiency.

3、 Move the vehicle. Each tank-type aerobic fermentation system is generally composed of 8-10 fermentation tanks. However, there is only one tipping machine. In order to save equipment investment, multiple fermentation tanks share one organic fertilizer composter. This requires that the tipping machine be switched between different fermentation tanks. The moving crane plays the role of moving the tipping machine and the distribution truck from one tank to another.

4、 Aeration system. The function of the aeration system is to ventilate and aerate the fermentation materials in the tank, so that the microorganisms in the materials can interact with oxygen, and then make the materials fully ferment to produce valuable humus. The fermentation days can be shortened by aeration.

It can be seen from the above introduction that the organic fertilizer tipping machine plays an important role in the whole compost fermentation process. It is necessary to buy a good tipping machine. The dumping effect is good and the efficiency is high. It also has the functions of mixing, crushing and displacement. It also organically combines the electro-hydraulic technology and has a high degree of automation. It realizes the functions of central remote control and one-button operation. According to the needs of users, it can also realize the real-time transmission of temperature, moisture, oxygen content, etc. in the pile.

The fertilizer manufacturing process of  bio-organic

(1) Preparation of microbial fermentation-based strain mixture

To produce bio-organic fertilizers, it is necessary to use bio-fermentation bases as strains. We use HM fermentation bases here. In order to bring more than 10 beneficial microorganisms such as nitrogen-fixing bacteria, potassium-resolving bacteria, phosphate-resolving bacteria, yeasts, actinomycetes, Bacillus megaterium, and Bacillus subtilis in HM fermentation base into contact with chicken manure more evenly A bag of 100 grams of HM fermentation base is divided into five equal parts, each 20 grams, in each HM fermentation base, add about 1-1.6 kg of wheat bran or soybean meal and other auxiliary materials, fully mixed evenly, we Call it a mixture of strains. In this way, about 200 kg of chicken manure can be fermented by each bacterial mixture.

(2) Two manufacturing methods:

The production of biological organic fertilizer for livestock and poultry manure can be divided into static processing and dynamic processing.

1. Technology of static processing and manufacturing of bio-organic fertilizer:

Static processing of bio-organic fertilizer is a self-made bio-organic fertilizer made by farmers in the field. It has a simple method, is easy to operate, has low investment, and is suitable for small professional farming households.

(1) Preparation of chicken manure and accessories

Choose an open space of about 30 square meters with flat ground, no water accumulation, and separate chicken manure and auxiliary materials.

In order to facilitate the mixture of strains and chicken manure to be evenly mixed, we divided 1000 kg of chicken manure into five equal parts. Each aliquot is about 200 kg.

Generally granular or powdered wheat bran, peanut shell powder, etc. as the main auxiliary materials, such as corn stalks, cotton stalks, etc. as auxiliary materials, they must first be cut into 5-10 cm length, too long will cause stirring inconvenient. The purpose of adding auxiliary materials is to adjust the water content and carbon-to-nitrogen ratio of chicken manure and increase the permeability of the fermented material.

(2) Construction of fermentation platform

After the chicken manure and auxiliary materials are prepared, a fermentation platform should be built according to the environment and the actual situation of the farmers.

When building a fermentation platform, choose a place that is sunny, flat, high in terrain, avoids air vents, and is easy to operate. First dig a number of parallel ventilation trenches, trench width 30 cm, depth 30 cm, trench beam width 20 cm. Spread branches, bamboo strips, straws, etc. on the ditch beams to form a bottom-permeable fermentation platform, which is convenient for ventilation and oxygen supply. Because the beneficial organism flora in the HM fermentation base belongs to aerobic strains, the fermented product can only be rotted better when the oxygen is sufficient.

After the fermentation platform is built, we can proceed to the manufacture of statically processed bio-organic fertilizer.

(3) Operation steps

Spread a mixture of strains evenly on the prepared chicken manure and mix well. During the mixing process, the water content of the chicken manure should be adjusted to about 60%, that is, hold a handful of chicken manure in the hand, hold it tightly, and see the water between the fingers but not drip. Let go of your hand and spread it out with a light touch. Such a water content is enough. If the water content is too high, add wheat bran, corn stover and other auxiliary materials to reduce the water content of chicken manure; if the water content is too low, add fresh chicken manure or sprinkle some water. Stack the stirred chicken manure on the fermentation platform.

Treat the other four piles of chicken manure in the same way, all piled together. At this time, the height is about 1-1.2 meters, the length and width are 1.5-2 meters square, the volume of compost is generally 1.5 cubic meters.

(4) Management of fermentation process

During fermentation, temperature control is very important. If the temperature is too low, it cannot reach the standard of maturation; if the temperature is too high, the nutrients of compost are easily lost. The temperature inside the compost is within 30 cm from the outside to the inside. Therefore, the thermometer used to measure the temperature, its metal rod must be longer than 30 cm, when measuring, it must be inserted more than 30 cm in the compost in order to accurately reflect the fermentation temperature of the compost.

Requirements for fermentation temperature and time:

After composting, chicken manure enters the first fermentation stage. It will automatically heat up to above 55 ℃ for 5 to 7 days, then it can kill most of the parasite eggs and harmful bacteria, reaching the harmless treatment standard. Turn the pile once every 3 days or so, which is conducive to ventilation, heat dissipation and rot.

After 7-10 days of fermentation, the temperature naturally drops below 50 ° C. Since some strains lose their activity due to high temperature during the first fermentation process, the second fermentation is required. Add 5-8 kg of strain mixture again and mix well. At this time, the moisture is controlled at about 50%. If you grab a handful of chicken dung in your hand, hold it tightly, the palm is wet, and there is no water seeping between your fingers, indicating that the water is suitable.

The temperature of the second fermentation must be controlled below 50 ° C. After 10-20 days, the temperature in the compost has dropped below 40 ° C, which has reached the maturity standard.

(5) Matters needing attention in the fermentation process

In the process of manufacturing bio-organic fertilizer by static methods, attention should be paid to:

Covering the surface of the fermented material with a layer of finely crushed straw of about 10 cm or sprinkling a layer of superphosphate can reduce the evaporation of ammonia gas and avoid the loss of nutrients.

In case of strong wind during fermentation, the top should be covered with straw and other air-permeable materials to reduce the evaporation of water and the loss of temperature.

Livestock manure is stored for too long or there are more straws and weeds in the manure, and less manure. You can add some rapeseed meal, urea or fresh chicken manure to increase the nitrogen content, increase the carbon-to-nitrogen ratio, and speed up the fermentation. Improve fertilizer quality.

The pH value of the compost should be controlled at 5.5-8.5. If the pH value of the compost is lower than 5.5, it is too acidic, and quick lime can be added for adjustment.

It should be avoided to produce bio-organic fertilizer in the open air during the rainy season as much as possible to avoid excessive moisture.

For example, during the process of composting, the moisture is too high and the permeability is poor, you can insert a few straws in the middle of the fermentation pile to help ventilation.

When the color of the bio-organic fertilizer becomes dark brown or yellow-brown, the surface of the organic fertilizer inside the compost has a lot of white hyphae, no raw chicken manure, no maggots, no odor, and a slight ammonia smell. The bio-organic fertilizer manufactured in a static manner has reached the maturity standard. It can be used as base fertilizer or top dressing directly in the field.

The above introduces the method of using small-scale static processing of chicken manure to produce bio-organic fertilizer. Farmers can arrange production according to local conditions according to different manure sources, site size and fertilizer demand.
