Manure fertilizer: advantages and disadvantages


The manure fertilizer it is nothing more than dried and humified manure to make it more 'manageable'. Humification is the process of digestion of manure by bacteria.

Manure can be purchased in specialized garden centers or online, in the form of dust or pellets sold in paper or cardboard bags of various sizes and is used to fertilize plants of all kinds.

Although at first glance it may seem like an artificial compound, the manure fertilizer is in effect a natural fertilizer obtained from the manure of sheep, cattle, equine and in some cases poultry farm animals. It is the alternative to chemical fertilizers when there is no fresh manure at the right degree of ripeness.

Manure: ownership

Manure fertilizer, being produced naturally, from the manure of various farm animals, has more nutrients than chemical fertilizers that are able to properly nourish crops but impoverish the soils, making them less suitable for germinating plants.

Manure can also be processed, thus being classified into three categories:

NPK: fertilizer containing nitrogen, phosphorus and potassium

NP: fertilizer containing nitrogen and phosphorus

NK: fertilizer containing nitrogen and potassium.

To determine the quality of the manure, reference is also made to the ratio between carbon and nitrogen, which should have an ideal value of 10, in order to optimize the chemical and physical properties of the soil.

Manure fertilizer: advantages

Manure fertilizer has numerous advantages: the first, as already mentioned, is that it is an organic fertilizer and therefore it can be used to fertilize organic productions. It is also suitable for gardening, fruit plants and flowers.

Manure fertilizer is also perfect for keeping the soil in perfect balance thanks to its ideal ratio of nitrogen to carbon. Being dry it is easily stored and transportable, thus becoming a perfect substitute for manure.

Two other advantages are that it does not give off strong unpleasant odors, precisely because it is "dry" and that it fertilizes gradually without risking damaging the crops.

Manure fertilizer: disadvantages

The disadvantages related to the use of manure fertilizer they are essentially of two types. The first is that it is less soil improver than manure and therefore it is not suitable for obtaining a very soft and rich soil.

The second drawback concerns the fertilization in the garden, vegetable garden and open field but concerns only a possible excessive use. The manure fertilizer containing animal manure is in fact polluting if it reaches the aquifers. The problem can be avoided by following the recommended doses and purchasing only fertilizer certified according to anti-pollution prescriptions.

Manure fertilizer: how to use it

The manure fertilizer it can be used to fertilize any type of plant, from the orchard to the vegetable garden, to the apartment. Depending on the purpose, a particular quality can be chosen:

  • fertilization of indoor plants: low nitrogen (N) content pellet manure is used, distributing a moderate amount on the soil surface before watering.
  • soil improver for garden and vegetable garden: pellet manure with a higher nitrogen content is used for the pre-sowing and pre-planting phase, an element that favors the rooting of new plants.
  • fertilization for garden and vegetable garden: manure in powder is indicated, and also in this case a good nitrogen content is recommended. The most suitable periods are the end of winter for vegetables and the beginning of spring for all the other plants in the garden.

The quality of the manure fertilizer it is also evaluated on the basis of the ratio of the mixture of carbon to nitrogen (C / N) of the organic substance. The ideal value is around 10 and shouldn't be that much higher or that much lower. As for the quantity, the doses are those recommended on the individual packs and following these 3 links you will find them for all needs:

Manure to produce a liquid fertilizer

The manure fertilizer in addition to being used directly on the ground, it can be used to produce a liquid fertilizer, with a proportion of one kg of manure per 10 liters of water.

The advantage of a liquid fertilizer is that it is absorbed more quickly by plants or vegetables.
