97 % of a plant’s food comes from evapotranspiration of photosynthesis, the principal gases in atmosphere CO2, H, N, H2O, etc.
In other words, 97 % of plant material created in a growing season used to be, originally, a mix of solar energy and atmospheric gases. The remaining 3 % comes from the soil (that is what remains in the ashes after wood burning).
At Puy Arnaud we practice biological agriculture since 2001. Our first biodynamics attempts go back to 2005/2006.
We fully invested in this approach in 2008 and obtained the Biodyvin label in 2010 (Demeter in 2014).
This agricultural method, in cooperation with the agro-organic agriculture movement, connects people working locally with season cycles and the essence of their craft which results in an “Art to nurture the Earth.”
