Localisation of nitrate in the rhizosphere of biochar-amended soils
A wheat seedling rhizobox approach was used to differentiate between the rhizosphere and non-rhizosphere (bulk) soil amended with low and high rates of biochar (20 and 60 t ha −1 vs. control). Nitrate (NO 3 −) was added as the main nitrogen (N) source because emerging biochar research points to redu...
