A good wine starts from the vineyards, and its quality (about 75%) is guaranteed by the quality of the grapes, which depends on several factors, including the right choice of the agricultural land, the right choice of the graft-rootstock combination, the correct establishing of the vineyard plantation, the management of the soil, the proper protection of the vineyards from diseases and pests, etc. The secret to a good wine is related to the applied technology and the stages that each producer follows, starting with the establishment and exploitation of the vineyard plantations, continuing with processing the grapes, until the wine bottling.
The fertilization of the vine and its protection from diseases and pests are also stages that winegrowers are not allowed to neglect if they want to have an increased harvest of high-quality grapes and to reduce losses.
The topic was discussed in detail during the “Soil management and vine fertilization. Protection of the vineyard under the 2019 conditions” seminar, organized by the National Office for Vine and Wine. The event gathered together over 50 viticulture specialists, within wine-producing associations, as well as representatives of teaching and researching institutions in the field. The participants have been informed first-hand about the new technological trends, which ensure a higher quality both of the grapes and of the wine products made out of them.
The expert Franck MAZY, the founder of a consulting and expertise company in the wine sector in France, was invited to the event. He spoke to the participants about the best practices in his country, which are recommended by the experts of the National Office for Vine and Wine, to be applied by the winegrowers in the Republic of Moldova.
Vladimir COROBCA, lecturer, coordinating expert in DACCPV, ONVV: “In most cases, in our country the soil in the vineyards is maintained in the ‘black field’ system, and the fertilization of the vine is rarely done. Winegrowers prefer to apply foliar fertilization only. The best practices from France on soil management and vineyard fertilization show us a beneficial influence on the quality of grape and wines, due to the fertilization of the vine, using grassing of the soil in vineyards, causing water stress, using nitrogen and microelements, etc.”
According to the same practices, the protection of vines from diseases and pests can be insured 100% with the help of an integrated combat system, which also includes the reduction of the effects of pesticides on the environment. Winegrowers from the Republic of Moldova use pesticides to protect vineyards against diseases and pests, but their effect can only be guaranteed if the rules are followed, depending on the time and method of application, the amount of solution administered, compliance with the recommended rules on a given surface and the equipment they have at their disposal.
Even worse is that because of insufficient information and non-compliance with the recommendations in the field, some producers lose 20% and even 100% of the grape production.
During the event, the participants were also informed about ways to optimize the costs, in the case of soil maintenance and integrated vines protection systems, under the conditions of 2019.
Last year, Republic of Moldova had one of the most abundant grape harvests in the last 10 years, a performance that placed our country on the 19th place in the ranking of wine producers around the world. Our country remains the leader in terms of vineyard density around the world, in relation to the agricultural land surface. During the wine year 2018, the area of vineyards with domestic varieties and new selection varieties increased by 15%.
