The fertilizer is a fundamental element for the growth of plants, whether they are flowers, houseplants, fruit trees or vegetables. However, it is necessary to know how to choose the right fertilizer for each type of plant.

Organic fertilizers

These are natural fertilizers, that is, deriving from a biological activity. Organic fertilizer is the most suitable for many types of cultivation: since it does not contain chemical elements, it must necessarily be used in organic crops. It is a type of fertilizer particularly suitable for preparing the soil for a new sowing: it is rapidly assimilated by the earth, and contains the fundamental nutritional elements for each type of plant. There are different types on the market. Manure is undoubtedly the best known and most widespread, and comes from the excrement of farmed animals, which are processed in order to obtain this compound, suitable for many types of plants. Manure is in fact versatile, and is mainly used in agriculture. Another organic fertilizer is cornunghia, which derives from the processing of the horns and nails of slaughtered animals. It favors the development of plants because it improves the state of the soil, and for this reason it is used above all in orchards and agricultural crops. But the cornunghia is also suitable for indoor plants and lawns. Another fertilizer widely used for vegetable gardens and orchards (especially in the preparation of the soil) is the stillage, which is produced by processing the waste of sugar beet, and is found in different forms: from that in grains to the liquid one. Fertilizers whose use is more complicated, as they require a scrupulous dosage, are manure and guano: while the first is obtained from the excrement of chickens, the second is produced starting from the excrements of gulls and other birds living on the sea. Both are used for gardens, orchards and vegetable gardens. Bone meal is especially recommended in the cultivation of ornamental plants: however, it is to be avoided for plants that cannot tolerate calcium. One of the most effective fertilizers in agriculture is blood meal (which contains a lot of nitrogen).

Mineral and organo-mineral fertilizers

Mineral fertilizers are chemical ones, that is, they are obtained from industrially processed compounds. Also in this case, you can easily buy them in specialized shops, according to the needs of the plants that we have to fertilize. But organo-mineral fertilizers are also very common, that is, they derive from chemical and organic fertilizers worked together, thus forming a new compound, which combines the typical characteristics of organic fertilizers with the chemical elements necessary for a correct development of plants and preparation soil that has the desired success. They are to be recommended for various crops, as they contain more nutritional elements than organic fertilizers, and have greater efficiency than strictly chemical ones. They can be purchased in different forms, both liquid, solid and granular. In this way, you will also have the possibility to choose the method of administering the fertilizer. Of course, since these are chemical compounds, it is necessary to pay close attention to the dosage, following the advice of the manufacturers: some of these fertilizers, in fact, can alter the composition of the soil.

How to choose the right fertilizer

In the case of a large cultivation, the fertilizer should be chosen based on the nutrients naturally present in the soil. If the soil is too calcareous, for example, fertilizers with a high calcium content must be avoided. To find out the elements present in the fertilizers, it is possible to consult the package (it is a legal obligation to accurately report the doses of the chemical elements that make up the fertilizer) or ask for advice directly from the seller.

Of course, it is also possible to choose the most suitable fertilizer based on the type of plant we need to fertilize. If we are not experts in the subject and are afraid of making serious mistakes, we can therefore buy specific fertilizers, which are sold for certain types of plants. It is therefore possible to buy fertilizers for succulents, geraniums, fruit trees ... Basically, organic fertilizers are suitable for every type of need, and manure (one of the most common) is also suitable for garden plants and from apartment.

The fertilizer can also be chosen based on its consistency: there are many solid fertilizers, which have a prolonged release over time, and it is sufficient to place them on the ground to obtain the desired effect. They are especially suitable for potted plants, as the soil to be fertilized is limited compared to what a field can be. However, fertilizers must be administered to plants only at certain times of the year and their life cycle: this is another aspect to which attention must be paid. Usually, in winter we tend not to fertilize the plants, because this would cause a stunted growth of new twigs, leaves and shoots.
