Best Practices for Increasing Soil Organic Matter Impact Crop Yields
A study published in Soil Science Society of America Journal explored whether best management practices for increasing soil organic matter increased crop yields when they were applied on-farm. Although many studies have shown that increases in organic matter can increase crop yield, results from greenhouses and test plots don’t always apply at the farm scale. However, this study in the Midwest compiled data from 170 corn fields from 49 different farms to show that there is a positive relationship between the amount of soil organic matter and crop yields. The study also revealed that continuously corn-cropped fields were higher in organic matter, but fields that had more crop rotation delivered higher yields.
