Organic fertilizer

The organic fertilizer is composed of fertilizers derived exclusively from natural substances. The natural elements that give life to the organic fertilizer can be of animal or vegetable or mixed origin, that is partly vegetable and partly animal. After the unbridled use of chemical or synthetic fertilizers, that is, non-existent in nature and derived from industrial transformation processes, there has been a new interest in organic or natural fertilizers, also known as organic. The organic fertilizer it is in great demand by private consumers, while in large-scale agriculture it is still combined with traditional chemical fertilization.


Organic fertilization has undoubted advantages over chemical fertilization which has now ended up weakening the soils and making them not very fertile. Organic fertilizers, in fact, perform two important functions: one nutritional and another structural. The first serves to allow the growth of plants through the supply of fundamental nutrients, such as nitrogen, phosphorus and potassium, the second, to improve the quality and fertility of the soil. The structural function of the organic fertilizer it is sometimes higher than the nutritional one because the fertilizer substances bind more easily to the soil than to the plant, nourishing it and making it suitable for cultivation. This mechanism explains why organic fertilizer is strongly recommended in preparing the soil for the planting of new crops or new plants. In organic fertilizer, the nutritional fraction is absorbed by the roots of the plant, while the structural fraction remains fixed in the soil, improving and correcting its chemical and physical composition. Improving the physical chemical composition of the soil makes plants healthier and more resistant to disease.


According to the substance of origin and as already mentioned in the first paragraph, the organic fertilizer can be vegetable, animal or mixed. Among the organic animal fertilizers we remember the manure, the zootechnical sewage, the dried blood of slaughtered animals, among the vegetable fertilizers we remember the compost, the wood ash, the pomace, while among the mixed fertilizers, still the compost (if it includes also animal remains) and droppings. The latter is actually a semi-organic fertilizer because it is derived from the industrial processing of livestock slurry. Fertilization with manure and livestock manure has lost its usefulness due to the environmental disadvantages that it is able to cause during the fertilization process. Fresh sewage has the disadvantage of being difficult to absorb by the plant and the ground and of polluting the aquifers, as well as the disadvantage of emitting bad smells, while the droppings, or the same dried livestock manure, do not guarantee the absence of heavy metals from the animal waste, which is also fed with unnatural supplements. Furthermore, the sewage does not allow a uniform distribution of the fertilizer in the soil and not even the correct dosage of macroelements (nitrogen, phosphorus, potassium, calcium) and microelements (iron, zinc, etc.). The nitrogen of the sewage is dispersed very easily , both in the air and in the ground, while only phosphorus and potassium are assimilable. To enhance the absorption of nitrogen by plants and soil, mature or dried manure is used, which are simpler and less expensive to distribute, allow a slow release and better absorption of nutrients, with the advantage of not emit bad odors. Mature manure, also transformed into pellets, is used a lot for garden fertilization. The product, sold in packs of one kilo, is accompanied by all the indications to distribute it correctly on the ground during the planting phase (spring) or in autumn when the new plants have to be planted. The pellet derived from manure can also be used for potted plants, mixing it with garden soil and topsoil.


Compost comes from the transformation and organic fermentation of waste and waste materials. This product can also be used as an organic fertilizer and can be obtained by composting remains of fruit and vegetables, dried leaves and flowers, remains of wood, coffee, ash and animal excrement. No remains of plastic, bones, rubber, synthetic materials, coal ash or vacuum cleaner bags should be added to the compost. To balance the composition of nitrogen and carbon, compost must be obtained by combining green and wet waste with dry and dry materials. To facilitate obtaining the compost, shavings or rock flour and clay can also be added. The material must be chopped up to form a heap, and covered with a layer of straw or mown grass, in order to protect it from light and facilitate the entry of air which helps bacteria to decompose it. After about six months, the compost can be used as an organic fertilizer to fertilize potted plants and vegetables and to prepare the sowing soil. After a year, the same compost can be used to improve the structure of the soil and to enrich it with humus.

Organic pomace fertilizer

Even the waste substance of olive oil extraction, pomace, is used to obtain an organic fertilizer. The substance is sprayed with a biological liquid and then stored for about three months in a non-ventilated place to facilitate fermentation. The fertilizer obtained is used in agriculture to improve the soil structure and to nourish the plants, showing results that are decidedly superior to chemical fertilization. On the market there are also organic fertilizers derived exclusively from vegetable substances. These products are suitable for fertilizing the vegetable garden and aromatic plants in pots.

The KING Multipack 4Kg Organic Organic Fertilizer by Agribios is an extremely innovative organic fertilizer of excellence. Its special formulation, based on 100% organic humified organic substance, mycorrhizae and rhizosphere bacteria, makes it a unique fertilizer of its kind able to nourish in an extremely potent way and at the same induce greater resistance of the plant to thermal stress, water, parasitic attacks and fungal diseases,

With a content in organic carbon (C) on dry matter equal to 32% and humic and fulvic carbon of 10%. KING represents a excellence in the field of fertilizers. A fertilizer born from the collaboration of Agribios with important research institutes that it does not contain synthetic mineral elements.

Organic fertilizer: what are they

The organic fertilizer it is of very different types and characteristics, depending on its origin.
It can also present itself as liquid organic fertilizer or fit granular.
The most common are:

  • Manure, or manure, i.e. the excrements of farm animals, in particular those from barns, as the name suggests, mainly cattle and horses. It is one of the most used organic fertilizers in agriculture and is also available in a dried version, very useful for the organic vegetable garden or plants grown in pots in the city. The percentage of nutrients varies greatly depending on the species from which the organic fertilizer.
  • Guano, derived from the droppings of bats, sea birds and seals, which over time have dried and accumulated in deposits. The main areas of origin of this fertilizer rich in nitrogen, phosphorus and potassium are Chile and Peru.
  • Flagpole, made from feathers and feathers of poultry and farmed birds. It is an excellent source of organic nitrogen and biological carbon.
  • Blood meal, produced by the waste from the slaughter of animals. It has high amounts of phosphorus and is devoid of the other macro elements, but it contains other important secondary elements such as iron, sulfur and calcium.
  • Cornunghia, obtained from the horns and hooves of animals coming from the slaughterhouse, which are dried and then pulverized. It is a slow release organic fertilizer, rich in nitrogen and phosphorus.
  • Humus, the result of the transformation by earthworms of organic material present on the ground, which is digested and converted into a organic fertilizer rich in nitrogen, phosphorus, potassium and carbon.
  • Wood ash, obtained by burning the wood used to heat the fireplace or stove. It provides good doses of phosphorus, potassium, calcium and magnesium, the percentages of which vary according to the type of wood used.
  • Dried Borlanda, a fertilizer little known and especially useful for the fertilization of the vineyards, which derives from the fermentation and distillation of beet molasses, a by-product of sucrose processing. Contains high quantities of nitrogen, potassium and small traces of microelements.
