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 says that animal dung contributes organic matter to soil, which in turn improves microbial activity as well as water drainage and the soil’s general structure. Not all animal manure may be used as fertiliser; examples of manure that cannot be used include that of a cat, dog, or pig. Fertilizers made from cattle, fish, worms, and even bat guano are considered to be among the finest available. {{!! -!! Home gardeners are probably most used to working with the 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 dung contains a high concentration of nitrogen, but the addition of manure from dairy cows and horses provides a more well-rounded increase in soil 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. {{!! -!! Another kind of beneficial fertiliser obtained from animal waste is fish manure. Fish manure, along with other fish byproducts like fish meal and fish emulsion, may be used as a substitute for traditional fertilisers. 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. {{!! -!! The amounts of the macronutrients phosphorus and potassium that are found in fish faeces are lower, despite the fact that fish manure has a high nitrogen content. 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. {{!! -!! Because they take up so little room, worm compost bins are an excellent choice for backyard gardeners looking to produce their own worm-based fertiliser. This process is also referred to 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. {{!! -!! It is recommended on the website of the National Gardening Association that home gardeners who live in close proximity to zoos, fairs, or wildlife parks 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 dung from bats and birds has to have been composted or aged for a number of months.

Farm Animal Manures

Manure from livestock and other traditional farm animals is perhaps most familiar to home gardeners. Animal manures from cows, horses and chickens are commonly available and used as fertilizers, along with manure from sheep, goats and rabbits. Nutrient content is not the same for all livestock and farm animals, however.

For example, chicken manure has a high nitrogen content, whereas dairy cow and horse manures provide a more balanced boost of soil nutrients. Sheep and goat manures also provide needed nitrogen to soil, but they also add more potassium than dairy or horse manure. Livestock manure can be easily sourced from dairies, farms, horse stables and colleges and universities with agricultural or veterinary programs.

Fish Manure Fertilizer Products

Animal manure from fish, along with other fish byproducts such as fish meal and fish emulsion, is another excellent fertilizer derived from animal waste. Unlike livestock animal manure, which takes months to break down and make nutrients available for growing plants, fish manure is a fast-acting fertilizer that provides a quick nutrient boost to the soil.

Fish manure is nitrogen rich, but also provides lower levels of the macronutrients phosphorus and potassium. Fish fertilizer products can be applied and mixed into vegetable garden soil or used as a foliar spray directly onto ornamentals such as roses.

Worms and Vermicomposting

Worm fertilizer production, also known as vermicomposting, is ideally suited for home gardeners because worm compost bins require little space. The manure product left behind by worms is called worm castings, and it makes an excellent garden fertilizer. Worm manure provides a balanced source of nitrogen, phosphorus and potassium, as well as micronutrients; unlike fish manure, which can have an unpleasant aroma, worm castings are odorless.

In addition, worm manure will not burn plants or their roots, which can be a problem with livestock manures because of their high urea content. Another benefit observed with use of worm castings has been fewer problems with plant disease and insect pests.

Exotic and Other Animal Manures

For home gardeners who live near zoos, fairs or wildlife parks, The National Gardening Association website advises that exotic animal manure also makes a great garden fertilizer. Manure from animals as varied as alpaca, elephants, rhinos, zebra, ostrich and wildcats is rich in soil nutrients and an excellent source of organic matter that improves overall soil composition and structure.

Bat, seabird and pigeon manures also make some of the best garden fertilizers, although the nutrient levels may vary. For example, some bat guano has a high nitrogen content, but depending on its harvesting site, other bat manures may have more phosphorus. Bat and bird manure should be composted or cured for several months before application.
