Biochar: for better or for worse?
This thesis presents biochar state of the art and investigations into the environmental benefits and potential impacts of biochar application to soil. Specifically, the opportunity biochar has to increase concentrations of potentially toxic elements (PTE) and polycyclic aromatic hydrocarbons (PAHs) …

The effects of biochar on soil mineral availability
Biochar is an organic soil amendment, produced by treating biomass feedstock at several pyrolytic temperatures and applied pressures in an oxygen limited environment. It is considered as a renewable resource that can be used to mitigate problems concerning both soil fertility and environmental …

Immobilization of Tetrabromobisphenol A On Pinecone-Derived Biochar
… TBBPA from aqueous solution by pinecone-derived biochars was investigated. The surface structures and functional groups of biochars produced at different temperatures were characterized through synchrotron-assisted FTIR analysis. The adsorption isotherms were well described by the Langmuir model. …

Pyrolysis Processing and Feedstock Impact on Biochar Soil-Plant Interactions
<p>Biochar properties depend on pyrolysis process and feedstock source. Objectives of this research were to evaluate the effects of four biochars developed from two feedstocks, switchgrass (Panicum virgatum L.) and corn stover (Zea mays) using two methods of pyrolysis (fast and slow) on: 1. water …

Restoration of Eroded Lands with Biochar as Soil Amendment in South Dakota
<p>Biochar is produced from incomplete pyrolysis of plant biomass. Due to the unique properties of biochar such as a higher number of micropores, surface area and carbon content, and recalcitrant nature of carbon, biochar is hypothesized to improve physical and hydrological properties of soil. This …
