Composting Biochar Creates 200 Nanometer Organic Coating

This won’t be news to the one person following this blog but researchers have now quantified the result of composting biochar.

Researchers found that dissolved organic substances played a key role in the composting of biochar and created the thin organic coating.

“This organic coating makes the difference between fresh and composted biochar,” Kappler said. “The coating improves the biochar’s properties of storing nutrients and forming further organic soil substances.” Hagemann added that the coating also developed when untreated biochar was introduced into the soil — only much more slowly.

Organic coating on biochar explains its nutrient retention and stimulation of soil fertility

Rather than composting I prefer soaking my biochar in organic liquids like aged urine (nitrogen and phosphorus), worm tea (plant growth hormones), and compost/extracts.
