The Science and Benefits of BioChar

The long pores provide significant surface area. In fact, 1 gram of our BioChar has a surface area of up to 500  square meters.

 

Our Biochar has both a cation and anion exchange ability that electrostatically attracts certain types of molecules in the soil, air, and water. The molecules are attached to the walls of the Biochar, where the roots can access them throughout the growing season. Biochar becomes a capsule rich in nutrients  and releases sustained and consistent  nutrition for plants, and is a major reason why our Biochar is so effective at promoting superior plant growth, health, and yields.

More Unique Benefits

Our BioChar was tested for water holding capacity and found to hold 5.6 times its weight in water. And because the pores are very long compared to their openings, there is very little evaporation (see Figure 1 Left). When the roots do not consume the isolated water, they are held for long periods of time.

For microorganisms, the canals and the pores of the BioChar look like a large housing complex (see Figure 2 Above) so they move in to form a community. After colonization, they are protected from precipitation of water that would otherwise disperse them. With our BioChar, microorganisms thrive and help create living soil.

"Biochar dates back thousands of years to a civilization in the Amazon Basin."

  • Biochar's history dates back thousands of years to civilization in the Amazon Basin, where vast areas of dark and very fertile soil known as Terra Preta - in Portuguese "black soil" - were discovered and analyzed, revealing high concentrations of charcoal and organic matter and materials such as plant and animal remains. Found only in populated areas, the presence of Terra Preta indicates that humans were intentionally responsible for its creation.
  • Soil scientists theorize the ancient Amazonians used a “slash-and-char” process to develop this rich soil. With slash-and-char, plant material or crop remains were cut, ignited, and buried to smolder (rather than burn), which eventually produced char, now commonly referred to as “BioChar”. This process isolated most of the carbon in the vegetation, creating a particularly hospitable amendment, which in turn nurtured beneficial micro-organisms that transformed the degraded soil to extremely rich and stable humus.
  • For centuries the slash-and-char technique produced the fertile soil – often referred to as the “Secret of El Dorado” – that supported the agricultural needs of the Amazonians, which in turn, enabled their numbers to grow by the millions. From this ancient method Biochar Now has developed the technology for producing BioChar as a means to improve today’s soil quality and store carbon.
  • Biochar Now BioChar filtration process is used to purify producer water from wells.  Our BioChar removes pollutants allowing for the discharge of clean water.
