Well-rotted manure is a great way to provide essential nutrients to the soil. It can be an ideal fertilizer if used well. Many gardeners also use it for soil amendment as well as an energy source. 

The rotted manure is usually stored manure that does not have any unpleasant smell. It has a changed texture and is suitable for soil amendment. The best thing about well-rotted manure is that it does not produce any burning in crops. 

You will also not notice any excessive foliar growth on using it in your fields. In some parts of the world, people store these manures in piles with steep for years. 

By doing so, they can retain inherent nitrogen, which is beneficial for the soil. However, if you want to boost the microbial action, you will keep some moisture in a pile. You will learn more about well-rotted manure in this article.

How Well-Rotted Manure Affects the Soil?

If you want to get the maximum benefits from well-rotted manure, you will require applying it correctly. Most experts recommend using manure by combining it with compost. 

Mixing the manure with compost is one of the best ways to benefit the soil. By doing so, you can minimize the chances of plants burning. Other than this, try tilling the soil before the spring planting. 

I prefer to till the soil during the winter or fall season as it will give better results. Most gardeners favor the fall season as they believe it is the best time to use manure as it provides more time for manure to break down. 

Well-aged manure is also a great source of fertilizer for plants. On the other hand, there are various manures that you can use to improve the performance of your soil. However, keep in mind not to use dog or cat manure as many experts do not recommend it. 

Both the cat and dog manure are not suitable for compost piles or gardens. Some of the most common manure fertilizers are horse, chicken, and cow manure. However, some people also prefer using rabbit and sheep manure. 

Though most of these manures are readily available all over the world still, if you are struggling to find these manures, you can visit your nearby garden centers. You can easily access various kinds of manures from garden centers.

Moreover, after adding manure to the soil, you will notice that the soil begins to absorb it after a short time—the absorption of manure by the soil results in the release of nutrients. 

This will improve the quality of the soil and boost the growth of plants present in the soil. Another benefit of manure is that it can help you improve the condition of the sandy soil. 

Sandy soil usually has a low moisture level which makes it difficult to grow various plants. By adding manure to the sandy soil, you can improve the moisture level to provide a better plant growth environment. 

Apart from the sandy soil, you can also use the manure of various other types of soils. For example, you can loosen the compacted soil by adding manure to it.


Types of Manure

Food is digested differently by animals, and each animal eats a different kind of food; because of that, the result varies. Due to differences in results, you may notice various types of manures available. Following, you will learn about the types of manure and their benefits.

Chicken Manure

Chicken manure is quite popular all over the world as it is beneficial for the soil. Similar to other birds, chickens also have high metabolisms. The chicken body temperature is also high. 

The best thing about chicken manure is that it can help prevent the weed seed’s growth. If there are still any weed seeds left in your garden, they can be removed by all poultry manure. 

The mixture of urine and feces of different poultry can help you because it contains a high amount of nitrogen. Further, the manure of a fresh chicken is quite powerful if you apply it directly; therefore, before using make sure to compost it fully. 

You can also use the chicken manure as a good addition to the compost pile. You can also mix it with high carbon matter such as leaves. Remember that the NPK rating of mature chicken manure is around 1/1.5/0.5, due to which you should use it accordingly.

Cow Manure

If you are searching for well-balanced manure, then you should prefer cow manure. It is among the most balanced manures which promote organic growth. The nature of cows’ stomachs helps them to provide such quality manure. 

Cows usually consume a high number of plants, which results in easy-to-break manure. The cow manure also contains some moistness that makes it easier to use during the composting stage. 

Further, it is not too strong in the case of nutrients. Therefore, if you want many nutrients for your soil, you should go for some other manure. If we look at the NPK rating of cow manure, it is around 0.8/0.5/0.5.

Well-Rotted Horse Manure

Well-rotted horse manure is well-balanced that is present abundantly. Compared to cows, horses do not digest their food thoroughly, due to which they produce a bit of different manure. 

The manure produced by horses is richer in organic matter. They provide nitrogen-rich urine, which is very much optimal for the garden. However, one issue you may face with well-rotted horse manure usually has viable weed seeds. 

Therefore, you should use it with care to get the best outcome. Furthermore, the NPK rating of rotted horse manure is 0.5/0.3/0.4, beneficial for a vast range of soils.

Slurry & Tea

In some parts of the world, gardeners also use slurry and tea as manure. They use cow manure and add it to a concrete basin. After adding, they mix water to make a slurry and spread it in fields using different machines. 

This slurry is ideal if you have a large area to cover. Apart from this, you can also use a mixture of manure tea and compost for a smaller garden. So, it is up to you which manure you want to use on your soil. Further, you can also make it in a bulk bag. The bulk bags will make it easier for you to apply.


Uses of Well-Rotted Manure

There are various benefits that you will get if you use the well-rotted manure correctly. Some of these uses are;

Soil Improver

Most gardeners use manure as a soil improver. It can help you improve the soil structure within no time. You can also use garden compost, composted bark, etc., to enhance the soil quality. 

However, if you truly want the manure to give you the best outcome, ensure to apply it correctly. Overusing the manure might become harmful to the soil. 

On the other hand, applying manure less than the required amount might not give you the outcome. Most experts recommend using around 5 to 10kg of manure per square meter to improve the soil. Experts also suggest applying a more wet material than the drier organic matter to get better results.

Use As a Mulch

Another benefit of well-rotted manure is that you can also use it as a mulch. You can also add bark, woodchip, leaves, and woody waste to make it a suitable mulch. However, remember that manure will take more time to break down if you use a coarser material. 

So, it is up to you whether to choose manure with coarser material or not. Make sure only to add the required amount of manure as a mulch to obtain the best output. 

This will help add all the valuable nutrients to the soil, which will help the plants to grow well. Not only this but also the addition of manure will also offer required moisture to the soil, resulting in positive root growth. 

It will strengthen the roots resulting in stronger and healthier plants. Experts also suggest using well-rotted manure rather than using fresh manure. 

Fresh manure is not recommended because they are hot, making them dangerous for plants. Fresh manure can damage your plants which you will never want. Therefore, try only to use well-decomposed manure on your soil.


The well-rotted manure can be very promising for the soil if you use it the right way. It is an organic matter produced by various animals like chickens, cows, and horses. 

Apart from these, some gardeners also use pig manure, rabbit manure, and even mushroom manure, as they are also quite beneficial. Depending on the soil, you can use any animal manure. 

However, before applying any manure, make sure to learn about the soil. Know whether the soil needs that type of manure or not. 

Also, check the nitrogen, phosphorus, and potassium level of the manure. By knowing your soil requirement and nitrogen, phosphorus, and potassium level of the manure, you can easily provide the required nutrient to the soil.
