This study evaluated the effects of chisel plow tillage vs. no-till systems and two nitrogen fertilizer application practices on the nitrate concentration of subsurface drainage from corn/soybean rotation plots. The results indicate that chisel plow tillage with late-spring, soil-test-based nitrogen fertilizer application for corn (after soybean) is a sustainable option in northeastern Iowa.
