Biodynamics can be understood as a combination of “biological dynamic” agriculture practices. Sheiner (1924) recommended eight preparations; two of them are stirred in water in a specific way and sprayed on fields and crops, the other six preparations were added to farmyard manure, slurry, liquid manure, plant litter compost and other type of organic materials in order to improve their fertilizing properties. The preparation 500 consist of high quality FYM (farmyard manure), fresh or aged, put in bovine horn, then buried at the end of September and dug up in April; after that it can be stored under controlled conditions for some months and finally sprayed to the soil. The Podolinsky’s method is actually based on frequent polyphytic green manuring, crop rotation and conservative soil tillage plus the use of the new “Prepared 500” preparation. The new Podolinsky’s preparation derives in fact from the combination, via a specific procedure, of the original Preparation 500 + all the compost preparations, as provided by Steiner.
