Bio-dynamic farming was developed by a German scientist, Rudolf Steiner, in the 1920s. The idea behind it was all about helping the soil be the most fertile soil possible, and to work with the plants and animals raised on that soil. In the ’20s, a lot of farmers were becoming concerned with the quality of their crops based on the chemical fertilizers they were using. They had noticed that the quality of their crops was deteriorating.
Steiner went to work, believing that there were many factors involved in developing good soil that grows superior produce. He believed that soil fertility could be increased by using field preparations and compost preparations. The field preparations he developed are called 500 and 501 — these are the ones that involve stuffing a cow’s horn with manure and planting it in a field for the winter, then digging it in the spring in time for field preparation for planting. Compost preparations consist of herbs stuffed into the stomach of a red deer, or the lower intestine of a cow, and left in the sun for the summer, then buried in the winter and dug up for use in the spring. These preparations, six in total, are dubbed 502-508.
Planting your crops is based on the cycle of the moon and whether it is a root, leaf, flower or fruit type of crop.
Annual crops are rotated from year to year in order to stimulate the soil.
There is no scientific evidence that bio-dynamic farming produces any better results than organic farming, and it sure seems like it’s a lot more work than organic farming. However, I have spoken to bio-dynamic vineyard owners who swear by it and say that the flavour of the terroir so much more pronounced in bio-dynamic wines versus wines made from conventionally grown or even organic grapes.

Here is a great website on the practicality and reality of biodynamic vineyard farming – love the website url: “http://biodynamicsisahoax.com” !
For the record, while my farm family are bio-dynamic farmers, I have to admit, that if I were a farmer, I would fall on the organic side of things. The extra work involved to make a farm bio-dynamic just doesn’t have me convinced that it’s necessary. Also, when you think about the tiny amounts of “preparations” that are mandated for field coverage (1 tsp. per hectare), you have to question how much work the preparation would really do. Sorry to those bio-dynamic farmers out there for being a skeptic.
