Prepared by Rudolf Steiner in his conferences of 1924 , dynamic organic preparations are among the most outstanding practices of biodynamics.
Sometimes disagreeing for the uninitiated, their effects have nevertheless been eroded, Found by many winegrowers and degusters. The wines, produced from vineyards that have been bred, Of the pulverization of these specimens, are for the most part more straightforward, more digestible, with a better expression of the terroir and the minerality. The maturity / acidity balance is better.
The two certification bodies of biodynamics, Demeter and Biodyvin, take up the work of Rudolf Steiner. They require winemakers to use of horn dung, horn silica, as well as some composts of vegetal orgin.
Cow dung put into a horn is buried during the winter months. A microbial life of exceptional richness is then developped. In the spring, the horn dung is then stirred in rain water around 37 ° C in a dynamizer, & Gt; Free air. Water as well as "dynamized" & rdquo; Can then be sprayed on the vineyards within hours. Preparedness is generally carried out in a copper container or in a depth sufficiently deep to allow for an energetic stirring. The brewing, one minute of each cereal, Created A whirlwind, the vortex, To capture the energy. This should last about an hour.
100 grams of dung in 35 liters of water is enough for one hectare. The effects observed are a neutralization of soil PH, a more intense microbial life, and a better root penetration at depth. To obtain a biodynamic label, the winemaker must carry out at least one spray before the decay (exit of the buds). But some domains are up to date, Three passes in the spring, which are supplemented by a new spraying; Fall.
Then the horn dung acts essentially on the ground and the roots, silica is destined to The apex part of the plant. As Prepared 500, the 501 is unavailable. Of rainwater, but the silica is even more dilute than the horn: 4 grams per 35 liters of water. Too much is likely to cause the plant to break down. The solution is sprayed in the form of very thin, high pressure. This operation takes place in the spring (before or after decay) and after the harvest.
The mechanism of silica action is not yet well known, but it seems that it will intensify the photosynthesis. After the application of the pre - parat, the winegrowers also found that, Allows a better vertical hold of the vine, and especially a better maturity. Of the fruit, thus achieving an optimal sugar level without losing acidity. Required; Balance & The structure of the wine.
Maria Thun, who gave her name to this preparation has been one of the great experimenters in biodynamics. Her astral calendar is a reference in biodynamic agriculture.
Maria Thun dung compost consists of cow dung, mixed with basalt and eggshellh eggshell, aged for a few months in a barrel.
For 1 hecatre, 240 g of compost is stirred in about forty liters of water for twenty minutes. Biodyvin requires of a CBMT compost after the harvest and another one before the buds burst.
