The Importance Of Standard Biochar

Biochar and charcoal are similar materials with different purposes. Charcoal, a fuel and metal reductant,is considered to be the oldest man-made material. The advantage of charcoal is that it burns with less smoke, which is advantageous when cooking indoors. In addition, charcoal burns hotter than wood, which allows it to be used for metal forming, such as in blacksmithing.

Adsorption is a pivotal property that distinguishes biochar from other carbon-rich natural products. Adsorption also distinguishes superior biochars from less effective “agricultural charcoals”. Since biochar is so new, there are no analytical methods developed specifically to measure adsorption in biochar, nor any experience base to relate adsorption to biochar impact when added to growing system. Thus,  urgently needed the standard biochars. Following paper will give analytical options for biochar adsorption and surface area, please go here.
