ThisĀ set of BD Compost Preparations BD #502-507Ā 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 additionalĀ biological cultures and enzymes as part of a proprietary recipe. TheĀ Pfeifferā„¢Ā Compost StarterĀ brings the influence of all the compost preparations PLUS an even richer microbiological inoculation for aĀ fraction of the priceĀ of the BD compost preparation set. A single unit of theĀ Pfeifferā„¢ Compost StarterĀ costs $12.50 versus $26.40 for the BD Compost Preparation Set (aĀ savingsĀ of nearly $14Ā per unit).
