Several chemical and physical properties of biochars are analyzed in this work with the objective of drawing some relations, applicable to different biomasses, which allow the relation between production parameters, biochar properties and soil application. It has been observed that, independently of the material, a linear behavior is followed by the H/C and O/C molar ratios with respect to the volatiles content. That may allow the establishment of parameters for estimating the biochar stability in...
