文摘

Field-scale evaluation of denitrification bioreactors in cold climate conditions. Total-N and nitrate-N concentrations reduced, 72% and 99% respectively. Nitrate-N loading reduced by 99%. Environmental non-compliance events for nitrate-N reduced by 96%. Agricultural denitrification bioreactors are effective in cold, humid climates.
