Agronomic values of greenwaste biochar as a soil amendment
TL;DR: In this article, a pot trial was carried out to investigate the effect of biochar produced from greenwaste by pyrolysis on the yield of radish and the soil quality of an Alfisol.
Journal ArticleDOI
Effects of biochar from slow pyrolysis of papermill waste on agronomic performance and soil fertility
L. Van Zwieten,Stephen Kimber,Stephen Morris,K. Y. Chan,Adriana Downie,J. Rust,Stephen Joseph,Annette Cowie +7 more
TL;DR: In this paper, a glasshouse study of two agricultural soils with two biochars derived from the slow pyrolysis of papermill waste was assessed in a glass house study.
Journal ArticleDOI
Using poultry litter biochars as soil amendments
TL;DR: In this paper, two biochar types produced from poultry litter under different pyrolysis conditions were tested in a pot trial by assessing the yield of radish (Raphanus sativus var Long Scarlet) as well as the soil quality of a hard-setting Chromosol (Alfisol).
Journal ArticleDOI
An investigation into the reactions of biochar in soil
Stephen Joseph,Marta Camps-Arbestain,Yun Lin,Paul Munroe,C. H. Chia,James M. Hook,L. Van Zwieten,Stephen Kimber,Annette Cowie,Bhupinder Pal Singh,Johannes Lehmann,N. Foidl,Ronald J. Smernik,James E. Amonette +13 more
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.
Journal ArticleDOI
Biochar's role in mitigating soil nitrous oxide emissions: A review and meta-analysis
Maria Luz Cayuela,L. Van Zwieten,Bhupinder Pal Singh,Simon Jeffery,Asunción Roig,Miguel A. Sánchez-Monedero +5 more
TL;DR: In this paper, a meta-analysis using published literature from 2007 to 2013 showed that biochar reduced soil N2O emissions by 54% in laboratory and field studies and that the biochar feedstock, pyrolysis conditions and C/N ratio were key factors influencing emissions.
