Chicken Manure Composting: A Guide For Filipino Farmers

how to compost chicken manure in the philippines

Chicken manure is an excellent natural fertilizer and soil amendment, but it must be composted first. Composting chicken manure can be done in as little as 18 days or up to a year, depending on the method. The Berkeley method of hot composting, for example, can break down chicken manure into safe, garden-ready compost in just over two weeks. Chicken manure is high in nitrogen, so it's important to balance it with carbon-rich brown materials like bedding, shavings, sawdust, or straw. The ideal ratio is 2 parts brown to 1 part green (manure), and the pile should heat up to between 130 and 160°F to kill pathogens. This process can be sped up with a vertical fertilizer fermentation tank, which can compost chicken manure in just 15 days. In the Philippines, chicken manure fertilizer production lines help dispose of chicken waste and turn it into valuable fertilizer granules.

Chicken manure compost benefits

Chicken manure is considered a valuable asset for home gardeners. When properly composted, it can provide numerous benefits for your garden. Here are some advantages of using chicken manure compost:

Improves Soil Structure and Fertility

Chicken manure compost is an excellent source of organic matter. It enriches the soil by adding essential nutrients such as nitrogen, phosphorus, and potassium. These nutrients are vital for plant growth and help improve soil fertility. The compost also increases the water-holding capacity of the soil, making it better at retaining moisture, which is beneficial for plants and can reduce the need for frequent watering.

Enhances Plant Growth

The nitrogen, phosphorus, and potassium in chicken manure compost act as natural fertilizers. These nutrients are readily available to plants, promoting their growth and overall health. Chicken manure compost can lead to more vigorous plant growth, larger blooms, and higher yields of flowers and vegetables.

Reduces Plant Diseases

Proper composting of chicken manure helps eliminate pathogenic organisms such as Salmonella and E. coli. By breaking down these disease-causing organisms, the compost helps reduce the risk of plant diseases that could harm your garden.

Eco-Friendly and Cost-Effective

Composting chicken manure is an environmentally friendly way to recycle waste and turn it into something beneficial. It reduces the need for chemical fertilizers, as the compost provides plants with the nutrients they require. Additionally, it is a cost-effective method for improving soil health and plant growth, as you create a valuable resource from materials readily available on your homestead.

Space-Efficient

Chicken manure compost can be created in a relatively small space. For those with limited areas, vertical fertilizer fermentation tanks can be utilized to compost chicken manure efficiently without requiring extensive room.

Hot composting methods

Hot composting is a faster method of composting chicken manure than cold composting. It entails more maintenance and requires you to maintain the compost pile at a temperature of 104-160°F (60°C-72°C or 130-150°F in other sources) for an extended period. This temperature range is high enough to kill most pathogens and weed seeds.

To start hot composting, select an area for your compost pile or bin, ensuring it is away from your chickens and enclosed to keep rodents and flies away. You can then begin adding brown and green materials in a ratio of 2 parts brown to 1 part green (or a 1:1 ratio, depending on the type of bedding used). Brown materials are natural materials rich in carbon, such as dry leaves, woodchips, and paper, while green materials are natural materials rich in nitrogen, including chicken manure, grass clippings, and kitchen scraps.

Once you have a decent pile, turn the compost regularly to introduce oxygen and accelerate decomposition. Monitor the moisture level, adding water if it seems too dry or covering it if it is already moist and rain is expected. The ideal moisture level will allow you to form a ball with the compost, but the ball should easily break apart when you apply pressure with your fingers.

Maintain the temperature range mentioned above for at least three days in a row, checking the temperature daily. Turning and stirring the pile will help maintain the temperature and introduce oxygen, aiding the process. After approximately 90 days or up to a year, your chicken manure should be transformed into rich compost, ready to be used in your garden.

Moisture content

Chicken manure has a high moisture content, which can negatively impact the composting process and the quality of the final product. To achieve effective composting, the moisture level should be carefully monitored and adjusted.

Fresh chicken manure is a mixture of solids and water, with a moisture content that can exceed 80%. To prepare the manure for composting, it is important to reduce the water content to a suitable level. This can be achieved by adding absorbent materials with low moisture content, such as straw, corn cobs, peanut cake, or rice husks. These materials can be mixed with the chicken manure or placed at the bottom of the fermentation groove to absorb excess water. By doing so, the moisture content can be decreased to the optimal range of 50%-60% for effective composting.

Another method to quickly and easily remove excess water from chicken manure is to use a fertilizer dewatering machine. This machine can efficiently separate solid chicken manure from water, reducing the moisture content to approximately 30%. This mechanical method allows for greater control over the moisture level and can expedite the composting process.

During the composting process, it is crucial to maintain the appropriate moisture level. The compost pile should be kept moderately moist, similar to the dampness of a well-wrung sponge. This moisture level can be achieved by adding water to the mixture and regularly monitoring it. Additionally, the colour of the plant material is indicative of its moisture content, with brownish plant litter suggesting higher carbon content and better compost quality.

The moisture level of the compost pile is closely linked to temperature management. To activate the microbes responsible for breaking down organic material, the compost pile should reach and maintain a temperature of 130-160°F for several days. However, temperatures above this range can be detrimental, killing beneficial microorganisms and slowing down the composting process. Therefore, careful management of moisture and temperature is essential for successful chicken manure composting.

Chicken manure fertilizer production

Chicken manure can be composted and used as a fertilizer for plants and gardens. It is a great way to manage chicken waste while investing in a healthy homestead. Chicken manure compost provides many benefits to the soil and your garden.

Chicken manure is too strong to be used directly on flowers or vegetables. It can damage roots and possibly kill plants. However, once composted, chicken manure is a good fertilizer and soil amendment. It provides nitrogen, phosphorus, and potassium to plants. Chicken manure also adds organic matter and increases the water-holding capacity and beneficial biota in the soil.

  • Collect the manure and bedding. Chicken owners normally use bedding such as shavings, sawdust, dry leaves, or straw to provide a dry cushion for chickens and to control odor and pests. The coop bedding can be collected with the manure and dumped into a composting bin.
  • Achieve the ideal carbon-to-nitrogen (C:N) ratio. Chicken manure is high in nitrogen, so a 1:1 or 2:1 mixture of carbon to nitrogen is recommended. You can adjust the moisture content of chicken manure by adding materials with low moisture content, such as straw, corn cobs, peanut cake, or rice husks.
  • Create a compost pile or use a compost bin. The recommended size is one cubic yard for efficient hot composting.
  • Turn and moisten the chicken manure and bedding. This process helps break down the material and stabilize the nitrogen as organic matter. The material should heat up to 130-160°F within 24-36 hours. Turn the compost again when the temperature drops below 110°F to reheat.
  • Maintain the temperature for hot composting. The compost pile should reach a temperature of 130-150°F and maintain it for at least three days. Heating is necessary to destroy pathogens.
  • Monitor and maintain the compost. Continue turning the compost and monitoring its moisture level and temperature. For chicken manure compost, allow it to compost for at least 90 days. The compost is ready when it does not reheat after moistening and turning.

For those looking for a faster composting method, a vertical fertilizer fermentation tank can be used. This method can compost chicken manure in as little as 15 days by slowing down heat dissipation and isolating the compost from outside temperatures.

Safety considerations

Safety is an important consideration when composting chicken manure. Here are some key safety tips to keep in mind:

Avoid Using Raw Chicken Manure

Fresh chicken manure contains harmful bacteria such as Salmonella and E. coli, which can be dangerous if transmitted to humans. It also has a high ammonia content, an unpleasant odour, and is too strong to be used directly on plants as it can damage their roots and leaves. Therefore, it is crucial to compost chicken manure properly before applying it to your garden.

Maintain Proper Ratios

The carbon-to-nitrogen (C:N) ratio is critical in composting. Chicken manure is high in nitrogen, so it is recommended to mix it with carbon-rich brown materials such as wood shavings, straw, or sawdust. The ideal C:N ratio for composting is around 30:1, but when using chicken manure, a 2:1 or even 1:1 ratio of brown to green materials may be more suitable.

Monitor Moisture Levels

Moisture plays a vital role in the composting process. The compost pile should be moist but not soaked, similar to a well-wrung sponge. If the pile is too dry, you can add water, and if it's too wet, you can rake it out to dry and then recombine the materials. Maintaining proper moisture levels helps regulate the temperature of the compost pile and supports the growth of beneficial microbes.

Achieve Optimal Temperature

Hot composting is an effective method for quickly breaking down chicken manure. The compost pile should reach and maintain a temperature of 130-150°F (54-66°C) for at least three days. This temperature range is optimal for destroying pathogens and weed seeds. However, temperatures above 160°F (71°C) can kill beneficial microorganisms, so be careful not to exceed this temperature.

Practice Safe Handling and Consumption

Always practise good hygiene when handling composted chicken manure. Wash your hands thoroughly after working with the compost, and avoid direct contact with your eyes, nose, and mouth. If you have a compromised immune system, avoid consuming raw produce from gardens fertilised with chicken manure compost. Cook all vegetables thoroughly before consumption to minimise the risk of foodborne illnesses.

Frequently asked questions

Chicken manure compost adds organic matter back into the soil and contributes nitrogen, phosphorus, and potassium to the plants. It is also a good fertilizer and can be used as a natural amendment to the soil.

The ideal mixture for composting chicken manure is one part manure to one part or more of bedding. The bedding can be made up of materials such as shavings, sawdust, dry leaves, or straw. The general rule of thumb for the ratio of brown to green materials is 1:2, but because chicken manure has a high nitrogen content, a 1:1 or 2:1 mixture is recommended.

The best method for composting chicken manure is hot composting, which entails more maintenance but converts the manure into compost faster. The Berkeley method of hot composting is a popular choice, which involves maintaining a temperature of 130-150°F within the compost heap for an extended period.

Depending on the method used, chicken manure can turn into compost in as little as 15-18 days or up to a year.
