Practically speaking this involves the following:
The farm as a whole organism. BD farms create all nutrients for the farm on the farm, such as maintaining livestock to supply compost production with manure.
Crop rotation. BD farmers grow crops to nourish the soil in between those grown for food.
Farm biodiversity. BD farmers set aside land on the farm for forest and non-farm animals to proliferate.
Use of special plant, animal and mineral preparations for the soil. Steiner came up with nine biodynamic preparations made from medicinal plants (yarrow, chamomile, stinging nettle, oak, dandelion and valerian) to replace toxic synthetic/organic chemicals put into the soil.
Use of buried animal parts to make soil preparations. Steiner believed that cow horns retain enzymes from the animal’s digestive system and act as a catalyst to further aid compost fermentation, thereby imbuing the soil with energy.
Recognition of rhythmic influences of the sun, moon, planets and stars. BD farmers use an astronomical calendar called the Stella Natura to determine auspicious planting, cultivating and harvesting times.
Ashing. BD farmers gather seeds or roots of problematic weeds and bugs, burn them, then collect the ashes and grind them by hand, dilute with water and spray infected areas for weed and insect control.
Community Sustained Agriculture (CSA). BD farmers pioneered this practice as part of Steiner’s philosophy of ‘anthroposphy’ or fraternity in the world’s economic sector.
