Blaustein Institutes for Desert Research, Ben-Gurion Univ of the Negev, Sede Boker Campus 84990, Israel, Dennis Timlin, USDA-ARS-ACSL, Bldg. 001, Rm. 342, Beltsville, MD 20705-2350, David Fleisher, USDA-ARS, 10300 Baltimore Ave, Beltsville, MD 20705-2350, and Yakov Pachepsky, Bldg.173 Rm. 203 Powder Mill Road, USDA-ARS, USDA/ARS, BA/ANRI/ESML/BARC-East, Beltsville, MD 20705.

Nitrogen is a critical nutrient for plants and is wholly taken up from the soil. 2DSOIL is a two dimensional finite element model of soil processes. We show the importance of passive and active modes of uptake of nitrogen in corn.
