Popis:	Point-injection technology is being developed to improve fertilizer management, particularly N management. This study was conducted to evaluate the effects of the rate (number) and timing of point-injections of an ammonium nitrate (NH 4 NO 3 ) solution on N uptake and corn growth and to measure any differences due to tillage. Nitrogen-15 depleted NH 4 NO 3 (AN) was hand-injected beside individual plants at the V1, V5, and/or V9 growth stages at rates of 50, 100, and/or 200 kg N ha −1 with fall moldboard plow (MP), fall chisel plow (CP), and ridge-till (RT) systems (...)
