Organic fertilizer

Organic fertilizer is that type of fertilizing substance of exclusively natural origin. All the elements that make up the organic fertilizer therefore derive from substances coming from the animal or vegetable world. In recent years, a new sensitivity, particularly attentive to the health of the environment around us and to proper nutrition, has meant that organic fertilizers became an almost obligatory choice for those who want to cultivate a personal garden. Unfortunately, for various reasons, not all commercial producers adhere to this philosophy and continue to use fertilizers of chemical or synthetic origin on a large scale. But if you want to set up your own production of vegetables, then the exclusive use of organic fertilizers is strongly recommended.

Organic fertilizer - organic fertilizers">Why choose an organic fertilizer

Most of the agricultural productions exploit the combination of chemical and biological fertilizers. The chemical-synthetic fertilization is based on the theory of the mere quantitative restitution of the elements that the soil, worn over time by crops, has progressively lost. It is not taken into account that the earth is a living, rich, pulsating and highly articulated element, whose vitality is strictly connected to factors far more complex than a simple mathematical equation. In fact, after a massive and prolonged use of chemical and synthetic fertilizers, it was realized that the earth, instead of increasing its fertility, drastically decreased it, exploiting and wearing out the residual energies derived from that stratification of humus (the so-called "old force ") Accumulated over years of organic fertilization, especially based on manure and compost. But, once this resource was exhausted, there was a drastic drop in the soil fertility rate. At the limit, chemical fertilization can be understood as a sporadic adjuvant to be used in particular situations and according to specific methods.

The organic fertilizer, on the other hand, precisely because of exclusively organic origin, has the advantage of enriching the land to be cultivated with all those microelements which, together, favor the particular mechanisms, very delicate and vital, which serve the soil to return to life, benefiting in this way to plants that will grow healthier, more resistant, luxuriant, balanced and certainly appetizing.

Organic fertilizers - organic fertilizer">What are organic fertilizers

There are numerous and different types of organic fertilizer and each of them can have its advantages and disadvantages. Mainly, however, we can group them into three main categories: organic fertilizers of animal, vegetable or mixed origin.

Animal fertilizers

It is necessary to know very well the properties and the consequent uses of organic fertilizers of animal origin, such as zootechnical slurry, manure (also called manure) or dried blood of animals for slaughter. This is because each has substantial differences that can alter the quality of your land for the good or the bad.

For example, slurry can negatively affect the fertilization process, creating environmental damage. In fact, they can damage and pollute the aquifers and are not very "digestible" by your plants also because they easily disperse some of the nutrients that should be assimilated by the roots, such as nitrogen, and distribute others in an excessively heterogeneous way. They also give off a bad smell that is difficult to tolerate and very persistent.

Manure, or manure, is instead a real panacea for your garden. It is the fertilizer par excellence. It is produced by mixing the excrements of livestock with the litter. Once accumulated, it is left to macerate for some time.

The most used, also due to its abundant availability and the resulting economic savings, is certainly bovine manure, while horse manure is more rarely used. The latter is by far more renowned and expensive than beef, but its qualities are truly excellent. Horse manure can be used in higher quality organic crops. On the contrary, we strongly advise against pig manure due to its underperforming characteristics.

- ash as a fertilizer">Vegetable fertilizers

Among the organic fertilizers of vegetable origin we remember instead compost (if prepared with elements of exclusively vegetable origin), wood ash, green manure (which, more than a real fertilizer, is an agronomic technique that enriches the soil with substances nutrients) and pomace (a substance obtained from olive oil processing waste).

The compost, totally "organic", is obtained through the fermentation of vegetable waste (the peel and torso of your apples, the dry leaves collected in the garden, the remains of the vegetable garden, etc.). From the maceration of these elements, carried out according to precise rules and well-calibrated methods, you will obtain an excellent fertilizer for your garden, rich as it is in nutrients and adjuvants.

Wood ash should not be thrown away, but it can be used to enrich the soil of your garden with potassium!

Green manure, as already mentioned, more than a fertilizer is an agronomic practice that consists in the cultivation of certain types of plants to be planted in your soil because they enrich it with organic substance while expanding the water reserves. More organic than that!

Pomace also enriches your soil with quality nutrients and simultaneously improves its composition. Try it: you will not be disappointed!

Mixed fertilizers

Among the mixed organic fertilizers we mention compost (which can be obtained from the combined decomposition of elements of vegetable and animal origin) and manure (it may contain traces of inorganic elements contained in the bird's diet).

Manure is obtained by industrially treating the manure of volatile animals. Even in this case, however, it is necessary to emphasize the environmental impact of this mixed fertilizer, more or less in the same way as livestock slurry. Furthermore, deriving from the dejection of farmed birds, it may contain traces of those non-organic foods these animals eat. It is dried and reduced into pellets that can be easily distributed in the field to be cultivated and contains good percentages of nitrogen, phosphorus and potassium.
