Vineyard fertilization

Vineyard fertilization

With the word vineyard or vineyard we mean a part of land that is dedicated to the cultivation of vines. Based on the farming method used, the vineyards are divided into: awning, alberello, pergola, spurred cordon, simple guyot and double guyot. The fertilization of the vine does not only concern a specimen of plant but refers to the entire crops called precisely vineyards. In the vineyards, the plants are arranged in rows and it is precisely in these that the fertilizer is administered. The fertilization of the vineyards is not a very simple practice since particular attention is required for the different vegetative phases in which the plants are found. The soil of the vineyards must be prepared before cultivation and must be fertilized both in the vegetative rest phase and in the production phase. The main objectives that arise through fertilization are basically three: to make plants resistant to parasitic attacks and climatic adversities / difficulties, to improve the production cycle and to improve the quality of the fruit and therefore of the wine that will be produced. The fertilizers to be administered, generally, are those that contain elements such as nitrogen, phosphorus, potassium and iron. The substances to be administered vary according to the quality of the soil used and the organic substances it contains. generally, they are those that contain elements such as nitrogen, phosphorus, potassium and iron.

The various phases


The first phase corresponds to the preparation of the soil for the cultivation of the vines and, usually, the soil must be prepared by administering organic fertilizers such as manure. To prepare the soil of a vineyard, the manure must be distributed with the broadcasting technique. We recommend that you take the utmost care in carrying out this distribution process. The ideal quantity to spread on the ground is fifteen quintals for each hectare of soil. Manure can be easily found in specific points of sale or in any farm. The second phase is that for the improvement of the production cycle and includes two fertilizations. Vegetative fertilization is the most important phase in the fertilization of vineyards, it is in this phase that an excellent quality is given to the fruit. The periods in which these fertilizations are to be carried out correspond to the spring period and the autumn period. The third and last phase corresponds to that of foliar fertilization, a phase in which fertilizers diluted in the water used for watering are administered. These fertilizations must be carried out in the event that there are nutritional problems or deficiencies that can derive from different causes.

Fertilization of planting and breeding

During the three phases, three different fertilization methods are distinguished, in this paragraph we will talk about plant and rearing fertilization. Plant fertilization consists in distributing an adequate dose of nitrogen to the soil so that it is then ready for cultivation. Nitrogen is an element that helps the plant during its development and promotes rooting. As for the breeding fertilization, it must be carried out during the vineyard development period. The fertilization period varies according to the period in which the plant was made, if the plant was made at the end of winter, fertilization must also be done a few days later. The fertilizer to be administered is a nitrogen-based fertilizer, while in autumn balanced fertilizers of nitrogen, phosphorus and potassium must be administered. Usually, the doses of fertilizer to be administered are two and a half or three quintals for each hectare of land. Adequate doses can only be calculated after carrying out analyzes on the composition of the soil. Once the results have been obtained, they must be compared with tables for the various types of vineyards and land used for cultivation.

Production fertilization

The third and last method of fertilization is that of production, it consists of three “interventions”: two are carried out in the spring and one in the autumn. The two interventions in the spring period must be performed at the end of January / beginning of February and at the end of spring / early summer. During the first two fertilizations, the plants are given nitrogen-based fertilizers, on the other hand, during the autumn fertilizations, nitrogen, phosphorus and potassium-based fertilizers are given. The quantity of fertilizer to be administered is three quintals for one hectare of land. As for the right dosage of fertilizer, it varies according to the organic substances present in the soil. In the event that, for example, the soil is already rich in Potassium, this element, it should be administered in smaller quantities than nitrogen and phosphorus. Generally, fertilizers must be broadcasted but, in this way, there is a risk of wasting a lot of quantity. In vineyards, fertilizers must be administered by rows or, alternatively, foliar fertilization can be used. Foliar fertilization, however, is a very expensive technique because it requires the possession of specific irrigation systems. For this reason it is the least used technique, or rather, it is used only in particular cases of nutritional deficiencies. it is a very expensive technique because it requires the possession of specific irrigation systems.
