Biochar and Liquid Condensate Trial
The design of the pyrolysis system used by Black Earth Products produces liquid condensates, these are sometimes known as liquid smoke or wood vinegar. The chemical make up of these liquid is extremely complex, very little research has been done with regards to using it as a fertiliser. It should be noted that the chemical make up of the liquid will change depending on the process, system design and feed stock used, these informal results are to show the potential of the liquid, but further trials, chemical refining and toxic element identification are required. The liquids used in this trial were produced using continuous flow pyrolysis at 550°C with a poultry manure and bedding material of wood shavings as the feed stock.
The results of the trial clearly show how well the Biochar holds/bonds and exchanges nutrients with plants. The liquid condensate was applied one prior to seed germination. Liquid condensate 5000 Lt/ha = 8ml in pot. Poultry litter Biochar 5 t/ha = 8g in pot
