Effect of biochar on microbial community composition and enzymatic activity
Biochar helps hold water, saves money
Biochar offers several benefits as a soil amendment, including increased soil fertility, carbon sequestration, and water-holding capacity in nutrient-poor soils. In this study, soil samples with and without biochar additives were collected for two consecutive years from an experimental field plot to examine its effect on the microbial community structure and functions in sandy soils under peach-trees.
A comprehensive quantification of global nitrous oxide sources and sinks
Biochar’s benefits for the long-term sequestration of carbon and nitrogen on American farms are clear, but new research from Rice University shows it can help farmers save money on irrigation as well. The study showed that sandy soil, in particular, gains ability to retain more water when amended with biochar.
Biochar makes concrete stronger and more watertight
Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion1 and climate change.
A team of researchers from the National University of Singapore (NUS) has developed a novel new method to recycle wood waste [as biochar] by incorporating it into cement and mortar mixtures, making the resulting materials both stronger and more watertight.
