This study evaluated the effects of tillage, manure application, and inorganic fertilizer application on nitrate leaching from the root zone of corn fields at the University of Maryland’s Central Maryland Research and Education Center. The study showed a significant positive correlation between fertilizer rates and nitrate leaching. The results indicate that no-till corn cultivation is a viable method for reducing nitrate leaching.
