Effect of biochar on carbon fractions and enzyme activity of red soil

Biochar affects soil organic matter cycling and microbial functions but does not alter microbial community structure in a paddy soil

“…1) confirmed the role of BC in contributing to C storage in soil (Lehmann et al, 2006;Demisie et al, 2014). Biochar is a very C-rich substrate, and it is also resistant to decay due to its aromatic structure; e.g., only approximately 6% of the initially added BC was mineralized to CO 2 during the first 8.5 years of incubation (Kuzyakov et al, 2014).…”

“…The addition of BC to soil can differentially affect individual SOM fractions. For example, BC amendment increased the dissolved organic C content (DOC), microbial biomass C and light fraction organic C compared with un-amended soil (Demisie et al, 2014;Lin et al, 2012). Specifically, the microbial biomass was up to 43-125% higher in BC-rich soils than in BC-poor adjacent soils during 532 days of incubation (Liang et al, 2010).…”

“…These contradicting positive and negative effects of BC application on SOM fractions may be attributed to the specific processes governing C and N cycling under specific management practices. These processes vary with climate, crop rotation, fertilization and soil biology characteristics and consequently result in inconsistent SOM dynamics and transformation (Demisie et al, 2014;Jones et al, 2012;Lin et al, 2012;Liang et al, 2010;Prommer et al, 2014).…”

Adsorption of bovine serum albumin and urease by biochar

“…Demisie et al also reported that 0.5%, 1% and 2.0% oak wood biochar and bamboo biochar significantly improved the urease activity in a degraded red soil. [10]. It is thus clear that biochar will inevitably interact with soil enzymes, but this interaction is overlooked.…”

Biochar research activities and their relation to development and environmental quality. A meta-analysis

“…Publications prepared entirely by authors associated to institutions in countries with a human development index of <0.670 was low (18%), but it clearly indicates a successful scientific South-South cooperation due to collaboration among these countries (e.g. Demisie et al 2014;Ibrahim et al 2013;Zhang et al 2012). Similarly, contribution of mixed groups (i.e.…”
