PurposeFew studies have examined the effects of biochar on nitrification of ammonium-based fertilizer in acidic arable soils, which contributes to NO3− leaching and soil acidification.Materials and methodsWe conducted a 42-day aerobic incubation and a 119-day weekly leaching experiment to investigate nitrification, N leaching, and soil acidification in two subtropical soils to which 300 mg N kg−1 ammonium sulfate or urea and 1 or 5 wt% rice straw biochar were applied.Results and… CONTINUE READING
