Horn manure and horn silica

The agricultural and winegrowing activities of our wineries have been organic certified since the production year of 2015 and this recognition has been added to the biodynamic practices already applied in almost all of our estates. 


This means using natural products for protection from pathogenic
micro-organisms and insects, for controlling weeds and for fertilising.
An agricuture based on the respect for the soil and biodiversity.


In the subsoil of this small truffle field, the preparation 500, or “horn manure”,
is produced, which, together with the preparation 501, or “horn silica”, represent two essential biodynamic preparations.



Horn manure  (500)

The 500 is prepared from fresh manure from the Alpine cottages of Castelmagno. The cow horns, filled with manure, are buried in the wood in autumn and stay there until April: by then they have become odourless loam, which is kept in vases placed in special wooden drawers and insulated with a layer of peat. 


Before being used as a fertiliser it has to be “dynamised”, that is diluted in water and stirred, in a clockwise and anti-clockwise direction, for at least an hour.


  • Take fresh manure
  • Put it inside the cow horn
  • Bury the horn in the forest fall/winter
  • Preserve in jars
  • Dilute in water rotating clockwise and anti-clockwise


Horn silica (501)

The 501 is prepared by crushing white quartz crystals into powder then mixing to a paste with water and pressed into the cow horn, then buried in the wood. Once it is taken out, it is diluted, dynamised and sprayed, forming a cloud on the leaves of the plant, on a day when the sky is clear. The rays of the sun create a prism effect as they penetrate the compound and amplify the stimulating effect of the light on the vegetation.

  • Take quartz cristals and crush them into powder
  • Put them inside the cow horn
  • Bury the horn in the forest spring/summer
  • Spray it over the plants
