Flow Farm
Making a Tlud Barrel unit
Peter Hirst came and supervised the construction of our Adam Retort Bio Char system seen in the top pictures.


Did You know?:


Biochar is a 2,000 year-old practice that converts agricultural waste into a soil enhancer that can hold carbon, boost food security and discourage deforestation. The process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water.


This makes a significant positive contribution to the preservation of our environment!


In the first phase the wood in the retort chamber is dried by hot flue gases and the carbonization process is initiated. The hot flue gases are produced with waste wood pieces in an external fire chamber. By waste wood we mean small branches, twigs, pine cones and other residual products. About 100 lbs. of waste wood is burned per batch.


As soon as the water in the wood has evaporated, the vapor produced is sufficiently hot enough and the first inflammable wood gases appear, the smoke is now rerouted and burned off in the hot fire chamber, reducing pollution.


This additional energy is used to heat up the wood chamber and to further accelerate carbonization during this second stage. Between 1300 - 2000 lbs. of wood (dry weight) can be loaded, from which 450-750 lbs. of charcoal can be created.


Benefits of using Biochar in your soil


  • Immediately lowers your soil acidity

  • Improves your soil quality, adding very badly needed nutrients for your garden, and acts as a long-term fertilizer (often with significant results in plant growth and yield)

  • Helps the soil retain nutrients (like nitrogen, calcium, phosphorus), compost, and beneficial microorganisms much more effectively than unimproved soil.

  • Helps your plants utilize and absorb more nutrients from the garden soil, particularly when used in conjunction with compost or well-rotted manure (thus packing your vegetables with a higher nutrient content).

  • Reduces the amount of carbon released into the atmosphere (ie. greenhouse gases)

  • Reduces groundwater pollution.

  • Reduces the need for irrigation.
