Ecological viticulture. An alternative to conventional viticulture.
What is organic viticulture?
What advantages does organic viticulture offer us?
Recommended practices in organic viticulture.
- Fertilization with materials of organic origin such as compost, green fertilizers, harvest residues …
- The control of pests and diseases is carried out with the correct nutrition of the plant, creating conditions for the development of insects and other beneficial organisms that control them or prevent the proliferation of pests and diseases of the vine, although methods of physical control (capturing insects with a trap) and with permitted substances (sulfur).
- The increase in diversity within and around the vineyard, with different plants that stimulate the diversity in general, of beneficial organisms in particular, and promote favorable climatic conditions for the development of the vineyard.
- The control performance for quality fruit.
- A series of careful handling, during the production, harvest and winemaking process.

Ecological viticulture. Soil disinfection.
The approach for an ideal organic viticulture is to work on a land that has never been planted as a vine or that has been without a vine for at least 5 years, although in most cases, this is not possible and the winegrowers are obliged to plant the vine. vineyard without hardly leaving the land fallow.
The main problem that arises is the presence of nematodes in the soil . In addition, these nematodes can affect the development of young plants when they are found in significant quantities in the soil.
A non-ecological solution to this problem could be the chemical treatment for the disinfection of the soil through fumigation or dispersion of granules. This process has certain limitations, since it is inefficient at a certain depth of the soil and in clay soils, the application conditions are limited. The cost is high and has negative impacts on the environment.
An economical and suitable solution for organic viticulture to limit the presence of nematodes is to carry out a moldboard work on the ground in midsummer (if the type of soil allows it) at about 40 – 60 cm. Nematode populations are most important at this depth. The sun’s rays and the heat allow to burn a good part of the population.
