摘要：
The objective of this study was to determine the effect of different tillage methods on NH4+-N, NO3--N, and K+ movement through soil. Tillage methods in research used were moldboard plow (MP), spring-tine cultivator (C), and no-tillage (NT). NH4+-N, NO3--N, and K+ concentrations of soil samples taken fi om each plot at six depths (0-30 cm depth in 5 cm increments) of different tillage treatments all planted corn (Zea mays L.) were measured for before and after top-fertilization and after corn harvesting. Differences among tillage treatments were not statistically significant.
