Impacts of adding biochar on nitrogen retention and bioavailability in agricultural soil

Interest in the use of biochar to improve soil productivity has rapidly increased. Nitrogen (N) loss, retention and bioavailability in biochar-amended soils fertilized with NH4+–N and NO3−–N were studied using leaching and pot experiments. NO3−–N leaching from the soils fertilized with NH4+–N and NO...
