Positive associations of soil organic matter and crop yields across a regional network of working farmsEmily Oldfield, Mark Bradford, Abigail Augarten, Eric Cooley, Amber Radatz, Timothy Radatz & Matthew Ruark
The amount of soil organic matter (SOM) is considered a key indicator of soil properties associated with higher fertility. Despite the ubiquity of assumptions surrounding SOM’s contributions to soil functioning, we lack quantitative relationships between SOM and yield outcomes on working farms. We quantified the relationship between SOM and yields of corn (Zea mays L.) and silage for a dataset of 170 fields arrayed across 49 farms in a network of growers based in Wisconsin...
