Printing Process: Electrophotography Biodynamic agriculture involves a series of biological processes, such as grassing, composting, planting and sowing compatible plants, and integration of crops and livestock. The principles of biodynamic agriculture have been set one hundred years ago by Dr Rudolf Steiner, an Austrian philosopher and educator born in Donji Kraljevec, Međimurje, present-day Croatia. Biodynamic wines are made from grapes which have not been treated with chemicals, herbicides, or pesticides. In order to do this, the winemakers make special natural preparations, which are used to treat the soil and the grapevine. One such wine is the premium organic Šuran wine.
