In this work, we analysed the effects of traditionally composted farmyard manure (FYM) applications with two types(Yarrow and All) of biodynamic additions that had been applied for over 27 years on the same trial soils. Results showed that: a) repeated manure supplementation increased soil microbial biomass carbon; b) the addition of the six biodynamic preparations to manure counteracted the above effect; c) the addition of the single preparation from yarrow (Achillea millefolium) to manure did not affect the increase of soil microbial biomass carbon due to manure, and its mean value higher than that of manure alone, d) known microbial communications models from quorum sensing and other cell-to-cell signalling notions are consistent with the explanation of how the observed effects can be explained on a quantitative basis.

Abstract

In this work, we analysed the effects of traditionally composted farmyard manure (FYM) applications with two types(Yarrow and All) of biodynamic additions that had been applied for over 27 years on the same trial soils. Results showed that: a) repeated manure supplementation increased soil microbial biomass carbon; b) the addition of the six biodynamic preparations to manure counteracted the above effect; c) the addition of the single preparation from yarrow (Achillea millefolium) to manure did not affect the increase of soil microbial biomass carbon due to manure, and its mean value higher than that of manure alone, d) known microbial communications models from quorum sensing and other cell-to-cell signalling notions are consistent with the explanation of how the observed effects can be explained on a quantitative basis.
