It is vital to have a thorough preparation of land in order to have a proper and a successful establishment of the growth of wine grapes. In the first two or three years of production, the quality of soil isn’t very good. It generally consists of poor organic matter. In order to improve the quality of soil, it is then mixed with the different organic matters or a number of other fertilizers. In order to grow the wine grapes, the land where the wine grapes is to be growth is trenched towards a width of around 0.6 meter to 1 meter and have a depth of around 0.8 meter to 1 meter. The distance which is between the trenches depends on the distance that is between the rows. Thereby, the soil needs to be mixed with a number of other fertilizers. The humidity in China is generally very high. It is highest either during the summer seasons or the rainy seasons. This is the time when a large number of fungal diseases and infection may attack the wine grapes. It is during this time when a large number of diseases may impact the wine grapes.
The humidity required and the overall amount of rainfall in France is around 800-900 mm. The optimum rainfall which is required for the growth of grapevine is around 710 mm during the growth season. The maritime climate in France and New Zealand has the most rainfall that can have serious impacts on wine grapes. This also means that there is high amount of humidity for the grape wines in France and New Zealand.
One of the primary reasons for the production of grape wine in France has the best variety of soil in the entire world. Some of the common types of soils are present in France include Châteauneuf-du-Pâpe that is the soil covered with the pudding stones, which is formed from the flood waters that are being poured through the Rhone Valley, Alsace. It is the volcanic soil, stony and consists of granite, Bordeaux which consists of the pounds of gravel that spreads out similar to the ripples in pond. And the Burgundy which consists of the limestone clay that is heavy in nutrients and consists of the fossils of shellfish. The soils that are in New Zealand are also good for the production of wines, which are better than the one in China. Some of the common soils include the alluvial soils and the Wairau soil. On the other hand in the Waipara region, there is soil consisting of limestone deposits.
