Biodynamic Farming: Organic, Sustainable Agriculture with a Mystical Twist 2 Cascine Orsine has been following biodynamic principles since 1976, thanks to Giulia Crespi�s son, Aldo Paravicini Crespi. While it�s not clear exactly which methods the farm uses on their rice crops, they are certified by Demeter, the first certification and labeling system for organic production, created in 1924. The Demeter association of biodynamic farmers holds the �biodynamic� trademark and requires that Demeter organizations meet specific international standards, including agronomic guidelines, greenhouse management, structural components, livestock guidelines, and post-harvest handling and processing procedures. According to their website, in 2013 Demeter biodynamically certified about 4,800 farms worldwide. (Wednesday June 11th, 2014 — Oryza.com - San Francisco, California USA)
