TLDR
In this article, chitosan-modified biochars were synthesized in efforts to produce a low-cost adsorbent for heavy metal environmental remediation, and the results showed that the coating of chitosa on biochar surfaces could improve its performance as a soil amendment or an adorbent.About:

A review of biochar and its use and function in soil
TL;DR: The potential to sequester carbon as thermally stabilized (charred) biomass using existing organic resource is estimated to be at least 1 Gt/yr − 1 and biochar, defined by its useful application to soil, is expected to provide a benefit from enduring physical and chemical properties.

Positive and negative carbon mineralization priming effects among a variety of biochar-amended soils.
TL;DR: In an effort to better understand the interaction of pyrogenic C and soil organic matter (OM), a range of Florida soils were incubated with a variety of laboratory-produced biochars and CO 2 evolution was measured over more than one year as discussed by the authors.
