Many biochars have a complex carbon lattice structure with aromatic and aliphatic domains, acidic and basic groups, vacancies, metallic and non-metallic elements, and free radicals. Biochars also have separate mineral oxide, silicate and salt phases, and small and large organic molecules. In the rhizosphere, such constituents can be involved in chemical and biological processes along a soil–microbe–plant continuum, including nutrient cycling, metal chelation and stabilization, redox reactions… 

The Electrochemical Properties of Biochars and How They Affect Soil Redox Properties and Processes

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.

Organic coating on biochar explains its nutrient retention and stimulation of soil fertility

This work identifies a complex, nutrient-rich organic coating on co-composted biochar that covers the outer and inner (pore) surfaces of biochar particles using high-resolution spectro(micro)scopy and mass spectrometry, which strengthens biochar-water interactions and thus enhances nutrient retention.

Structural and Functional Features of Chars From Different Biomasses as Potential Plant Amendments

Two types of wood pellets, plus digestate and poultry litter, were separately converted into biochar using different technologies: pyrolysis/pyrogasification or catalytic (thermo)reforming, and it was shown that biochars from animal origin were phytotoxic at lower concentrations than those from plant feedstock.

Nanoscale organo-mineral reactions of biochars in ferrosol: an investigation using microscopy

AimsIn this study, a chicken manure biochar (CM biochar) and a paper sludge biochar (PS biochar), prepared under similar treatment conditions, were amended into ferrosol as part of an agronomic field

The Biochar Effect: plant resistance to biotic stresses

There are indications that biochar induces responses along both systemic acquired resistance (SAR) and induced systemic resistance (ISR) pathways, resulting in a broad spectrum controlling capacity in the canopy.

Dynamic molecular structure of plant biomass-derived black carbon (biochar).

A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.

Biochar: Agronomic and environmental potential in Brazilian savannah soils

A B ST R A C T Due to the high activity of microorganisms, the loss of soil organic matter is high in tropical regions. This loss becomes even greater if the soil is managed improperly or when there

pH-dependent mineral release and surface properties of cornstraw biochar: agronomic implications.

Improved soil fertility as a result of enhanced cation retention by the biochar probably will be favorable only in sandy and low organic matter soils, unless surface oxidation during aging significantly increases its CEC.

Characterization of slow pyrolysis biochars: effects of feedstocks and pyrolysis temperature on biochar properties.

It is demonstrated that biochars are highly heterogeneous materials that, depending on feedstock and HTT, may be suitable for soil application by contributing to the nutrient status and adding recalcitrant C to the soil but also potentially pose ecotoxicological challenges.

Immobilization of heavy metal ions (CuII, CdII, NiII, and PbII) by broiler litter-derived biochars in water and soil.

The results suggest that with higher carbonized fractions and loading of chars, heavy metal immobilization by cation exchange becomes increasingly outweighed by other controlling factors such as the coordination by pi electrons (C=C of carbon and precipitation.
