The soil amendment that animal manure provides is valuable for home gardens. It is rich in primary nutrients (nitrogen phosphorus, potassium, and potassium) as well as micronutrients that are essential for plant growth. The soil’s organic matter can improve soil structure, water holding capacity, drainage, clay soil drainage, slow release nutrients and encourage the growth of beneficial soil organisms. These manures are usually from herbivores, i.e. These manures are typically from herbivores (i.e., animals that eat plants), such as chickens, sheep, and cows.

Manure does not contain enough nitrogen to be available immediately for plants. Some of it can be stored in organic forms. Only soil microorganisms can decompose organic compounds and convert the N to NH4 to make organic nitrogen available for plants. This process takes place over many years. This conversion will vary depending on where the animal came from, what bedding it was given, how it was handled, temperature, moisture, and handling. The first year is when 30% to 50% of organic nitrogen is available. After that, the percentage gradually declines.
Fresh manure
Ammonium and soluble nitrogen are typically high in fresh manure. This means that fresh manure has a higher nitrogen content than composted. Over-applying poultry manure can cause rapid combustion. Fresh manure contains high levels of ammonia-nitrogen and should be mixed 6-8 inches within 12 hours. The atmosphere will lose a lot of the soluble nitrogen if it is not properly incorporated. The nutrient content will be reduced if the manure is added to bedding or litter. The C/N ratio can be increased if there is a lot of straw or sawdust. This may reduce the nitrogen availability for plants. A high ratio of carbon to nitrogen (greater that 25 /1) can tie up nitrogen.
Fresh manure can also contain high levels of salts, especially in poultry, turkey and other poultry manures. Salt damage can be avoided by waiting 3-4 weeks after application before you plant anything.
Composted manure
The smell and some other problems associated with fresh manure can be eliminated by composting. Because it is less moist, it is lighter and easier for people to transport. If the pile heats up above 145 degrees F, the composting process can kill pathogens and weed seeds. However, salts can be more concentrated and some nitrogen may be lost. This leaves the more stable organic forms. Composted manure is less fertile and has a lower nitrogen availability. However, it will have a greater organic matter contribution to the soil than fresh manure.
If composted manure is not applied at high rates, it may not be sufficient to provide all the nutrients needed for fast-growing plants. Although it is not necessary to incorporate composted manure immediately into the soil, it is better to wait until the soil reaches 6-8 inches to get the maximum benefit. It is better to wait at least one month before you plant your crops if composted manure has been spread in spring. This will ensure that the microbial activity it stimulates doesn’t hinder seed germination.
Nutrient availability
How much manure do you need? The label on bagged composted manure will give you information about the nutrient content as well as the application rates. It may be more difficult to determine if the amount of manure you are using in your garden is right or wrong if you have buckets of fresh, aged, or donated manure from a friend’s yard.
The nutrients in farm manure vary greatly depending on several factors. The breakdown and release of organic components will determine the availability of nutrients for plant growth. The manure will generally contain 70 to 80% of the nitrogen and 80 to 90% the potassium within the first year. It is difficult to calculate nitrogen availability because it depends on microbial activity.
Most cases, manure applications are based on the nitrogen content and availability for the first season. Keep in mind that manure can contain high levels of phosphorus so it is possible to add too much phosphorus to the manure. To determine if your soil has too much phosphorus, it is important to test it.
Manure can be beneficial for soil structure and nutrients, as well as providing nutrients to your plants. Too much manure can cause nutrient runoff, nitrate leaching and excessive vegetative growth. Fresh manure can be contaminated with pathogens if it is used in areas where food crops are grown.
