Chicken manure is a popular fertilizer for gardens due to its high nutrient content, including nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, and more. When fresh, chicken manure is considered hot due to its high ammonia content, which can damage or kill plants if not properly composted. The recommended composting time for chicken manure varies from five to six weeks to three to twelve months, depending on the method and climate. After this period, the manure becomes more stable and can be safely used to improve soil composition and fertility. However, the question arises: what happens if chicken manure is liquid and five years old? While there is limited information on the specific effects of aging liquid chicken manure for an extended period, it is safe to assume that proper composting and aging processes would significantly reduce the ammonia content and neutralize the pH level, making it less effective as a fertilizer but possibly useful for other applications.

Chicken manure is a good fertiliser
Chicken manure is often referred to as "black gold" and is considered a complete fertiliser as it contains 13 of the nutrients that plants require. It is especially beneficial for nitrogen-loving plants such as tomatoes, peppers, leafy greens, cucumbers, squash, sweet corn, pole beans, and rhubarb.
Chicken manure can be purchased in dried and pelleted form from garden centres, or it can be obtained from neighbours who raise chickens. It is important to note that fresh chicken manure should be composted or aged before being applied to plants, as it contains harmful pathogens and high levels of ammonia that can damage or kill plants. The composting process reduces these harmful organisms and stabilises the nutrients, making them more readily available to plants.
When applying chicken manure to your garden, it is recommended to start with a moderate amount, typically around 20 to 30 pounds of composted manure per 100 square feet. This amount can be adjusted based on soil condition and crop needs to avoid nutrient burn. For sandy soil, less manure may be needed to prevent drainage issues, while clay-based soil may require more manure. Chicken manure should be mixed into the soil or used as a top dressing for existing plants.

It is high in ammonia and needs to age
Chicken manure is a great source of nutrients for the soil in your garden. It contains nutrients like calcium, sulfur, magnesium, nitrogen, potassium, phosphorus, manganese, copper, zinc, and iron. However, chicken manure is also high in ammonia, which can be harmful. When exposed to moisture, ammonia gas is released, which is dangerous to the birds and those who care for them. It can also cause obnoxious odors in the surrounding areas.
If you have liquid chicken manure that is five years old, it is important to understand the process of manure composting to ensure it is safe to use. The composting process breaks down the manure and reduces the ammonia content. Ideally, chicken manure should be aged for a minimum of three months but preferably six months up to one year. The aging process depends on the composting method used. Hot composting in a warmed climate or sunny area will take around three months, while cold composting will take at least six to twelve months due to the slower breakdown of manure.
During the composting process, the ammonia in chicken manure decomposes back into its natural chemical state of nitrogen and hydrogen. Turning the compost pile frequently helps ensure that all areas of the pile are properly composted, reducing the risk of disease-producing organisms. Even with proper maintenance, it can be challenging to maintain the required temperature of 145 degrees F (63 degrees C) for three consecutive days to kill all pathogens.
By aging your liquid chicken manure for an extended period, you can ensure that the ammonia levels have decreased significantly, making it safer to use. Aged chicken manure can be beneficial for your garden, providing nutrients and improving soil composition. However, it is important to follow guidelines for application rates and safety precautions, especially for vegetables that come into contact with the soil.

It has a high pH level
Chicken manure is a useful source of nitrogen, the primary nutrient that plants need for green leafy growth. It also contains smaller amounts of other important nutrients. The pH level of chicken manure varies according to its age, the diet fed to the birds, the birds' age, and the litter materials used. Most poultry manure has a pH level ranging from 6.5 to 8.0, which is neutral to moderately alkaline.
If your 5-year-old liquid chicken manure has a high pH level, it is likely because of the birds' diet, age, or the type of litter material used. While the manure may still be beneficial for your garden, it is important to note that its high pH level can affect its suitability for certain types of plants. Poultry manure with a high pH level tends to be more alkaline. This makes it unsuitable for lime-hating (ericaceous) plants such as rhododendrons, azaleas, camellias, blueberries, and heathers.
To mitigate the high pH level of the manure, you can let it age further. Aged chicken manure tends to have a lower pH level and is less likely to scorch plants. It is recommended to let chicken manure age for a minimum of three months, but preferably six months up to a year. The aging process helps to stabilize the nutrients in the manure and reduces harmful microorganisms.
Additionally, when applying chicken manure with a high pH level to your garden, consider using it in conjunction with gardening or potting soil. Apply it in a thin layer, approximately 1-2 inches thick, over your garden each year. This will help to balance the pH level and ensure that your plants receive the right amount of nutrients without being overwhelmed.
By following these guidelines, you can still make use of your 5-year-old liquid chicken manure with a high pH level. Remember to always practice safe handling and application methods to prevent any potential issues with food-borne illnesses or harmful pathogens.

It is best used with a compost heap
Chicken manure is a great addition to your compost heap. Composting chicken manure is a fantastic way to manage chicken waste and invest in a healthy homestead. It is also a great way to make this activity more sustainable. Chicken manure is considered a complete fertilizer as it contains thirteen of the nutrients that plants require. These include nitrogen, phosphorus, and potassium, as well as other macro and micronutrients. Chicken manure compost provides many benefits to soil and your garden.
To turn chicken manure into compost, you must start a composting system and promote the composting process. There are two methods of composting: cold composting and hot composting. Both can turn chicken manure into compost. Hot composting entails a little more maintenance but converts the chicken manure into compost faster. With this method, you need to bring the compost pile up to 104–160°F for an extended period of time through proper management of moisture and turning. For hot composting, the perfect balance is said to be "one part brown (carbon) to two parts green (nitrogen)". You can also compost chicken manure by using a compost bin. It should be at least 1m cubed, and you can use almost anything strong enough to hold the contents together.
Cold composting needs minimal maintenance but composts your organic materials at a slower rate. For cold composting, you can start a compost pile and allow the materials to naturally decompose. You can stimulate the composting process by occasionally turning the composting materials, but just letting the materials sit and decompose will achieve the same results, just over a longer time span.
It is recommended that you let chicken manure compost age for at least three months, but preferably six months up to one year. If you use the hot composting method in a warmed climate or sunny area, you may only need to let the chicken manure compost age for three months since the manure breaks down more quickly into compost. For cold composting, you will want to age the chicken manure compost for at least six to twelve months since this composing process is slower.
