Abstract
Nitrogen fertility of high-value vegetable crops must be carefuiiy managed to prevent contamination of groundwater while meeting agronomic goals. New on-farm techniques of monitoring nitrogen are simple, quick and fairiy reiiable. Routine field monitoring in conjunction with periodic testing by conventional laboratory anaiysis can save time and money.
