The Best Animal Manure Fertilizers


When used and applied appropriately, fertiliser made from animal dung may provide both immediate and long-term advantages. The nutrients that are essential for the growth of healthy plants can be found in animal manures. In addition, the Mother Earth website notes that animal manure contributes organic matter to soil, which in turn improves microbial activity as well as water drainage and the soil’s overall structure. There are certain types of animal dung that are not acceptable for use as fertiliser: For example, cat, dog or pig dung aren’t useful. Fertilizers made from cattle, fish, worms, and even bat guano are considered to be among the finest available.

Farm Animal Manures

Home gardeners are perhaps the most acquainted with the use of manure produced by cattle and other conventional farm animals. Animal manures such as those from cows, horses, and chickens are readily accessible and used as fertilisers. Other types of animal manures, such as those from sheep, goats, and rabbits, are also utilised. However, the nutrient profile of various livestock and agricultural animals might vary greatly from one another.

For instance, chicken excrement contains a high concentration of nitrogen, but the addition of manure from dairy cows and horses provides a more well-rounded boost to the soil’s nutrients. In addition to supplying the soil with the necessary nitrogen, the manures of sheep and goats also offer a greater quantity of potassium than those of dairy animals or horses. Dairies, farms, horse stables, as well as schools and institutions that provide agricultural or veterinary degrees, are all excellent places to look for a supply of livestock manure.

Fish Manure Fertilizer Products

Another kind of animal waste that may be used to produce an excellent fertiliser is fish manure. Fish dung, along with other fish byproducts such as fish meal and fish emulsion, can also be used. Fish dung is a fast-acting fertiliser that delivers a rapid boost of nutrients to the soil, in contrast to livestock animal excrement, which takes months to break down and make nutrients accessible for developing plants. Fish manure may be used as a fertiliser.

Nitrogen is abundant in fish faeces, although phosphate and potassium are present in lesser concentrations than in other types of animal excrement. Fish fertiliser products may be sprayed directly onto the leaves of decorative plants like roses or put to the soil of vegetable gardens and blended in there.

Worms and Vermicomposting

Because they take up so little room, worm compost bins are an excellent choice for backyard gardeners looking to produce their own worm fertiliser. This process is also known as vermicomposting. Worm castings are a kind of manure that are produced when worms excrete their waste, and they are a great fertiliser for use in gardens. Worm castings, in contrast to fish excrement, which may have an offensive odour, are odourless and offer a balanced supply of nitrogen, phosphate, and potassium. Micronutrients are also present in enough amounts in worm manure.

In addition, worm dung will not burn plants or the roots of plants, which is an issue that may occur with animal manures due to the large amount of urea that is included in livestock manures. Castings from worms have been shown to have additional benefits, one of which being a reduction in the number of plant diseases and insect pests.

Exotic and Other Animal Manures

According to the website of the National Gardening Association, home gardeners who live in close proximity to zoos, fairs, or wildlife parks are encouraged to use the excrement of exotic animals as an excellent garden fertiliser. The manure produced by animals as diverse as alpacas, elephants, rhinos, zebras, ostriches, and wildcats is a good source of organic matter and has a high concentration of soil nutrients. This helps to enhance the general composition and structure of the soil.

Even though the quantities of nutrients in bat, seabird, and pigeon manures might vary, these types of manures are also among the most effective garden fertilisers. For instance, some types of bat guano have a high nitrogen concentration, whereas other types of bat manures, depending on where they were collected, may have a higher phosphorus level. Before being used, the manure from bats and birds ought to have been composted or aged for a number of months.
