Drainage improves waterlogged soil suitable for crop production. Similarly, no-till (NT) effects to improve soil’s functional capacity over plowing have been recognized. However, information on their long-term effects on soil properties is limited. A randomized complete block design was established to evaluate the impact of drainage and tillage (1983-2007) on particulate organic matter (POM) associated C (POC) and N (PON) content on drained and undrained Hoytville clay loam with corn-soybean rotation under no-till vs. annual plowing. The experimental plots used were established in 1982 with drain lines installed at 80 cm below the surface and spacesoil over time.
