Organic fertilization: how and when to practice it, what are the most suitable natural fertilizers for garden cultivation.

There organic fertilization is an agricultural practice that consists in improving the structure and characteristics of the land, using exclusively organic fertilizers. There organic fertilization therefore it greatly improves the physical and biological characteristics of the soil, providing all the nutrients and elements that the plants need.

Processing to incorporate organic fertilizer

Thereorganic fertilizationit's amustin agricultural practice. It should not be practiced alone but together with a deep working of the soil, generally performed by digging or hoeing. In practice thenatural fertilizerit must be buried by moving the first 30 - 40 cm of soil or sometimes even more.

There organic fertilizationmoreover, it can be carried out at the time of planting the plant. How you do it? In this case we proceed by adding del organic fertilizerat the bottom of the hole made for the new plant. Organic fertilizer is added to the hole intended to house the root system of the new plant, the fertilizer layer must be covered with a thin layer of soil. At this juncture, only very ripe organic fertilizers can be used, so as not to risk "burning" the roots.


Organic fertilizers are also soil improvers, that is, they are capable ofincrease soil fertility(then fertilize the soil) and modify its physical composition.

Please note: the heavier and more clayey the soil, the deeper the digging and the careful tillage must be. In the case of organic fertilization operated to improve the structure of a heavy and asphyxiated soil, it will be necessary to use organic fertilizers with the addition of sand.

Organic fertilization

There are many organic fertilizers available on the market. The photo above shows a nitrogen-based granular fertilizer. This is the classic slow-release chemical fertilizer. This fertilizer is artificial and is the antithesis oforganic fertilizationperformed withnatural fertilizers. What are the most used natural fertilizers?

Dried still: mineral and organic fertilizer, containing sulfur

The stillage is a organic fertilizer which is obtained from the waste from sugar beet processing and, in particular, from molasses. The fertilizer, which contains large quantities of potassium and microelements, is sold in liquid and granular form. Due to its large amount of minerals it is considered an "organo-mineral fertilizer".

The amount of phosphorus present in the fertilizer it is minimal, while nitrogen is present in moderate quantities. Being afertilizer potassium, is widely used especially in the field of fruit growing. In the field of horticulture this fertilizer it is also used in the pre-sowing phase.

The stillage is anatural fertilizerwidely used in organic farming. It brings a lot of organic nitrogen so as to support the development of the plant and potassium is useful for flowering and fruit production. It is most recommended for horticultural plants.

Where to buy it? In nurseries or by taking advantage of online sales. On Amazon, a one-liter pack is offered at a price of 8.90 euros with free shipping costs. The fertilizer must be diluted in water and added at the time of irrigation. For all information on the product mentioned:Compo Bio - 1 liter pack.


The cornunghia is considered one of the oldest fertilizers natural. Its derivation is given by the grinding, drying and sterilization of horns and hooves of animals coming from slaughterhouses, especially cattle. It is a fertilizer slow release, i.e. it gradually releases the nutrients contained, mainly represented bynitrogen and phosphorus.

It therefore contains little potassium but to remedy this, some producers integrate the nail horn with potassium salts to make it a more complete fertilizer. This fertilizer it is widely used in ornamental plants, lawns, but also in the vegetable garden and especially in the orchard, since the slow release excludes the washout and volatilization of the nitrogen added. There cornunghia it also improves the structure of the soil, promoting not only better plant development, but also the settlement of useful organisms in the soil. Cornunghia, like the other organic fertilizers examined on this page, is also a soil improver and acts on the grain of the soil, on the chemistry and the microbiological component of the soil.

Please note: the natural nail horn does not contributepotassium, even if there are specially compounded formulations on the market.


Manure is one of the most used fertilizers in organic fertilization, it derives from the manure of farmed animals and mainly from cattle, horses, sheep and goats which are subjected to special processing making it an easy to use and very versatile compound. There are different types of manure on the market: some have a nitrogen and phosphorus supply, others are further enriched with potassium, therefore more complete.

It's a fertilizer slow release, which guarantees prolonged supplies over time and above all avoids "burning" the roots of plants with excessive concentrations of nutrients. The manure is used in the pre-sowing phase, to fertilize the soil before the plants develop, or burying it at the end of winter.

Green manure

The green manure technique can be considered a work oforganic fertilization. Green manure works as a soil improver and restores a certain fertility to the soil. It is also known as green fertilization.
