TL;DR: In this article, a review describes the properties of biochar and suggests possible reactions that may occur after the addition of biochars to soil, including dissolution-precipitation, adsorption-desorption, acid-base, and redox reactions.

TL;DR: Water extracts obtained from twelve non-herbaceous biochars were tested by Liquid Chromatography - Organic Carbon Detection (LC-OCD) to identify the effects of both pyrolysis conditions and chemical treatments on WEOC content, and the utility of LC- OCD is demonstrated in providing an understanding of how biochar additions to soil can alter DOC.

TL;DR: In this paper, a chicken manure biochar and a paper sludge biochar were amended into ferrosol as part of an agronomic field trial, and the authors investigated interactions between these biochars and the soil after a 3 month trial.

TL;DR: Quantitative (13)C nuclear magnetic resonance (NMR) spectroscopy shows that the presence of the iron clay prevents degradation of the cellulosic fraction at pyrolysis temperatures of 250 °C, whereas at higher temperatures, the clay promotes biomass degradation, resulting in an increase in both the concentrations of condensed aromatic, acidic, and phenolic carbon species.

TL;DR: The redox processes that take place in soil and how they may be affected by the addition of biochar are reviewed and new methods and data for determining redox properties of fresh biochars and for biochar/soil systems are presented.
