Large Amounts of Nitrogen Stored Beneath Selected Agricultural Areas
American Society of Agronomy (ASA), Crop Science Society of America (CSSA), Soil Science Society of America (SSSA)Scientists use a new version of the Root Zone Water Quality Model to estimate unsaturated zone nitrogen mass balances at four agricultural fields. The new version of the model can make predictions down to 30 meters, enabling estimation of water quality effects well beyond the root zone.
