Cover crop impact on crop production and nutrient loss in a no-till terrace topography

Increased emphasis on implementation of conservation practices (terraces, conservation tillage including no-till or reduced tillage, and cover crops [CC]) have led to the integration of best management practices. However, research on integration of best management practices is limited. Therefore, a field trial was established at the University of Missouri Grace Greenley Research Center near Leonard, Missouri, to evaluate the effects of terraces with landscape positions and CCs on soil health parameters, CC biomass accrual, and no-till corn (Zea mays L.)–soybean (Glycine max [L.] Merr.) yields. Additionally, total suspended solids (TSS), nitrate-nitrogen (NO3-N), and total phosphorus (TP) export and discharge were evaluated from terraces with or without CCs.
