Increasing BiocharYield in Pyrolysis by Adding Ash

Abstract Wood ash additives increase biochar yield in pyrolysis via catalysis by alkali and alkaline earth metals. However, it remains unclear how ash and biomass properties govern the magnitude of this catalytic effect. Here, we pyrolyzed pelleted and ash-amended woody and grami...

Biochar as a Modulator of Soil Microbial Diversity and Enzymatic Function: Critical Insights and Ecological Implications

Biochar amendments can modify soil microbial communities and extracellular enzyme activities, but reported responses remain heterogeneous across soils, biochar types, and management contexts. This review critically synthesises current evidence to identify the conditions under whi...
