Summary

The biodynamic preparations have been investigated mainly in field trials. By contrast long-term project is to establish a rapid bioassay to evaluate the effectiveness of the
horn manure preparation (HMP). The investigated bioassay is based on hydroponically grown cress (Lepidium sativum L.) as an indicator plant. Past results indicated its sensitivity for typical dilutions of HMP in agricultural practice. However one limiting point was the use of non-standard local well water as hydroponic solution. The aim of the present study was to standardise this parameter. A series of 8
experiments was conducted to compare a selected mineral water with well water. The results indicate a highly significant (p<0,001) effect of the HMP on the root´s length
was more stable with the mineral water. The investigated mineral water therefore does ility. It can be concluded that
the bioassay can be standardised with the selected mineral water as hydroponic solution.
