Research ReportOne of the most important aims and objectives of the Bio-dynamic Association of India is the support of research projects on the bio-dynamic method of farming in India, and the dissemination of articles and reports as the result of research and experience by scientists and practicing BD farmers.

There has been some work done recently by Prof. Barbara von Wechmar, a microbiologist at the Stellenbosch University in Capetown, So. Africa, of growing fungi and bacteria samples from the BD preparations and CPP in the laboratory on various substrates. These all showed a tremendous variety of fungi and bacteria. The BD500 picture was described by Prof. Barbara as an interesting and beautifully balanced collection of fungi.

Work done at ICRISAT in Hyderabad, Andhra Pradesh, India has found beneficial bacteria, antagonistic towards Fusarium root fungus of chick peas, in compost treated with biodynamic preparations, which effectively combated the fungus.

Dr. Perumal from the MCRC Institute in Chennai, Tamil Nadu, India has tested the BD preparations for bacteria and particularly rhizobia. He found the BD500 cow horn dung and the BD504 Stinging Nettle have remarkably high numbers of this bacteria.
