Management practices such as relay cropping, cover crops, and no‐tillage may promote soil health in the North Central United States. However, soil health indicators in corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] systems involving multiple management practices are not well documented. The objective of this study was to determine the sensitivity of soil health metrics and the Soil Management Assessment Framework (SMAF) to contrasting management systems with different tillage, crops, and fertilization in a North Central US Mollisol. Different management systems, including conservation tillage and nitrogen fertilization strategies, cover cropping, and camelina [Camelina sativa (L.) Crantz] relay intercropping, were compared to a conventional corn–soybean system. Different systems did not affect most soil health indicators compared to the conventional system. Aggregate stability was the only indicator to …
