Q

WHO DEVELOPED BIODYNAMIC AGRICULTURE?

A

Biodynamic Agriculture-The development of biodynamic agriculture began in 1924 with a series of eight lectures on agriculture given by Rudolf Steiner at Schloss Koberwitz in what was then Silesia, Germany, (now in Poland east of Warsaw). The course was held in response to a request by farmers who noticed degraded soil conditions and a deterioration in the health and quality of crops and livestock resulting from the use of chemical fertilizers.

Q

WHAT IS CHLOROSIS AND WHAT IS A SYNONYM OF IT?

A

Chlorosis - Vine disorder in which parts or all of the foliage turns yellow due to lack of chlorophyll. Common in soils high in limestone. Sancerre, Burgundy and Champagne are areas where chlorosis is common. AKA green sickness.

Q

WHAT IS SYNONYM FOR COULURE?

A

Coulure (Shatter): Coulure is caused by an imbalance in the levels of carbohydrates in vine tissue. When these carbohydrates drop too low, the small berries drop off because their stems shrivel. Weather conditions which can reduce phtosynthesis will cause coulure, and thus periods of cold, cloudy wet weather around flowering can have devastating effects.

Q

WHAT IS FLURBEREINGUNG?

A

Flurbereingung – (Germany) (literally rectification of the vineyards)– A joint venture between growers and the German government which provides access roads and improved drainage systems and thus preventes soil erosion.
