# Complete Set of Biodynamic Compost Preparations (BD 502–507)

This set of BD Compost Preparations 502–507 treats up to 15 tons of manure or compost. The set contains fermented and potentized yarrow, chamomile, stinging nettle, oak bark, dandelion and valerian that increase the proliferation of beneficial fungi and bacteria, stabilize nitrogen, attract trace elements and stimulate the silica, calcium, potassium, phosphorus and sulphur processes.  
  
Dr. Ehrenfried Pfeiffer further developed the biodynamic impulse which not only has ALL the compost preparations (as well as BD500 horn manure) but additional biological cultures and enzymes as part of a proprietary recipe. The  Pfeiffer ™ Compost Starter brings the influence of all the compost preparations PLUS an even richer microbiological inoculation.
