Slide Background
What is wood vinegar?
Wood vinegar is often referred to pyroligneus acid or wood acid. It is a liquid substance produced in precisely controlled pyrolysis of biomass.

While a variety of biomass types can be used to produce wood vinegar, such as wood, crops, agricultural residues or different materials of biological origin, the most common types of biomass used are hardwood chips and sawdust.

Natural, organic product for agriculture

As a manufacturer of equipment suitable for production of wood vinegar, on this website we are introducing the production method and possible applications of the product.

Who We Are


Wood Vinegar Depot aims to create awareness about organic fertilizer, wood vinegar (Pyroligneous acid), and a global coalition connecting farmers with the resources they need to contribute to an ecologically sound food system and prosperous planet. The mission is carried out through the three pillars of the organization: information exchange, outreach and advocacy. Wood Vinegar, also called Pyroligneous acid, Liquid Smoke or Mokusaku, is a dark liquid produced through the natural act of carbonization, which occurs when a biomass is heated in an airless container during charcoal/biochar production.

Effects Of Wood Vinegar

Wood vinegar had been long known to be very effective against nematodes. It kills nematodes directly as well as propagates microbes that feed on them. The high acidity, methanol and phenol content have strong bactericidal effect at a high concentration, such as 50 to 100 times dilution. However, microbes propagate well when it is diluted to 200 times dilution. This is mainly due to the effect on the metabolism by its main element, acetic acid. Acetyl co-enzyme is produced by plants and microbes from acetic acid. Through the TCA cycle, acetyl coenzyme is converted into citric acid, malic acid, fumaric acid, succinic acid and other elements that are necessary for the plant and microbes. This is the main reason behind the propagation of microbes.

Plant Care

Five plant hormones are closely related to the growth and health of a plant. These are: gibberellin, cytokinin, auxin, ethylene and abscisic acid. Ethylene and abscisic acid contribute to the plant’s resistance against diseases and attacks from bacteria. An amino acid called methionine effects the formation of ethylene. The formation of etherlene is reduced by the excessive intake of nitrogen. On the other hand, growth hormones like gibberellin, cytokinin and auxin will be produced. As a result, the size of the plant increases but the resistance against diseases is reduced. The formation of oxidized ethylene from ethylene and the formation of methionine is accelerated by acids. The wood vinegar helps in their formation due to its acidity.
