TLDR
The sorption of PO4-P, NH4-N and NO3-N to cacao shell and corn cob biochars produced at 300-350°C was quantified and it is speculated that NH4 -N could bind via an electrostatic exchange with other cationic species on the surface of the biochar.About:

Insight into Multiple and Multilevel Structures of Biochars and Their Potential Environmental Applications: A Critical Review
TL;DR: In this review, multiple and multilevel structures of biochars are interpreted based on their elemental compositions, phase components, surface properties, and molecular structures to design a "smart" biochar for environmentally sustainable applications.
Journal ArticleDOI
Life in the ‘charosphere’ - Does biochar in agricultural soil provide a significant habitat for microorganisms?
TL;DR: In this article, the level of microbial colonisation on the internal and external surfaces of field-aged biochar was examined by scanning electron microscopy, and used 14C-labeled glucose to quantify the rates of microbial activity in different spatial niches of the biochar and the surrounding soil.
Journal ArticleDOI
Evaluation of slow pyrolyzed wood and rice husks biochar for adsorption of ammonium nitrogen from piggery manure anaerobic digestate slurry.
TL;DR: It is concluded that rice husk and wood biochar have potential to adsorb NH4(+)-N from piggery manure anaerobic digestate slurry, and thus can be used as nutrient filters prior to discharge into water streams.
