Biodynamics?

The truth about biodynamic viticulture.

There is much talk about this type of viticulture. Lots of strange preparations. No herbicides, no pesticides. Copper allowed. Stuff fermented in cow horn etc. etc. Some of the weird concoctions are:

Preparation 500 (horn manure) is prepared in autumn from a cow horn filled with cow manure and composted over winter when the soil forces are turned inwards. It is generally applied at the end of autumn and at the beginning of spring. It is applied to the soil and is ploughed into the soil straight afterwards. Its aim is to stimulate soil life.

Preparation 501 (horn silica) is prepared in spring from a cow horn filled with ground quartz and buried when the life cycle starts again.The quartz is rich in silica, which conducts light and electricity. The preparation is applied onto the plant in late spring and/or summer to stimulate the photosynthesis process as well as to boost the plants immune system.
