Fertilizer Management Effect on Recovery of Labeled Nitrogen by Continuous No‐Till

Improved fertilizer N management with respect to placement and timing is especially important in high-residue systems designed to improve N-use efficiency and to speed adoption of erosion controlling tillage practices. By means of point-injection technology, fertilizer solutions now can be applied and soil-incorporated with minimal disturbance of space residue or existing plants. This study was conducted in large non-weighing lysimeters (with reconstituted soil horizons) to determine the recovery of 15 N-labeled urea-ummonium nitrate (UAN) solution by continuous no-till corn (Zea mays L.) during the initial year of application and two subsequent years for four N management systems (...)
