Biodynamic compost is made in a heap into which the six compost preparations are inserted. It is then covered with straw, old hay, earth, etc.These preparations act on the compost and especially on the soil where it is spread. They don’t add nutrients to the soil, but mobilize elements in the soil and the cosmic environment. They work through the compost like a kind of “yeast”, increasing vitality and favoring soil health.Yarrow preparation (502)Achillea millefolium - Plays a specific role in mobilizing sulfur and potassium in the soil. Only the flowers (no stems) are used to make this preparation.Camomile preparation (503)Matricaria rectutita - This plant is related to the calcium metabolism and regulates the nitrogen process.Nettle preparation (504)Urtica dioïca - Related to nitrogen and iron, this preparation reinforces the influences of the first two preparations (502 et 503). It gives a certain sensitivity and “intelligence” to the soil and compost, promoting the formation of humus.Oak bark preparation (505)Quercus robur - Related to calcium, this preparation increases plant resistance to diseases due to excessive vigor.Dandelion preparation (506)Taraxacum dens leonis -  Among others, it plays an important role with regard to silicic acid and hydrogen. This preparation allows these elements to work in accordance with their intrinsic nature and acts upon the potash, limestone, and, ultimately nitrogen processes.Valerian preparation (507)Valeriana officinalis - Helps mobilize phosphorus in the soil and forms a kind of “warmth mantle” around and over the compost heap. It acts like a protective skin which is essential to all organisms. This preparation is also a powerful aid against stress..
