| Popis: | The fate of labeled N fertilizer applied to no-till corn (Zea mays L.) grown in nonweighing lysimeters was determined for 3 yr after application to evaluate NO 3 -N leaching losses from point-injection and conventional N management systems. In 1984, 15 N-enriched double-labeled urea-ammonium nitrate solution (UAN) at 200 kg N ha -1 was either surface-banded or knifed-in at the V1 growth state. It was also point-injected at either 200 or 125 kg N ha -1 in split applications at the V1, V5, and V9 growth stages (.) |
