Back in the island of Ré, during the wine grape harvest period, we went back to visit a wine maker whom a large part of his vineyard had been flooded with salty water as a result of the 27th Feb 2010 storm and who trusted us to apply our approach based on long forgotten fundamentals ( see our article – Rescuing soils after Xynthia storm )
To add to the matter, the spring and summer little rainfall evaporated fast. This resulted in a high concentration of salt within 25 to 40cm of ground stratum.
Salt in the ground asphixiates the plant preventing photosyntesis happening, it was important to treat the soil to allow it to feed the plant.
To unsaturate the soil from its sodium content it was necessary to provoke a chemical reaction.
We spontaneously introduced an agronomic protocol using Silibase at 1ton/ha to dilute the Sodium Ion.
As a result of post observations made on the ground, one can only note that as soon as one increases the CEC (Cationic Exchange Capacity) saturation level,then the plant-soil synergy works through Anions-Cathions exchanges.
A more than convincing result
Vineyard state after Xynthia storm
Vineyard after Getade natural treatment
Despite a dry climate conditions year, the vineyard at of end of September has a normal physiologic aspect. This is not the case for other vineyards that only followed an optimal standard approach.
Today, thanks to our ecologic approach and despite adverse climate incidents the winemaker has retrieved his livelihood with a vineyard “saved from water”
We have teachings to draw from this which will allow , I hope, us to go back to long forgotten fundamentals.
