This study analyzed the economic impacts of cover crops on cash crop yields using data from 20 farmers in central and northeastern Indiana over 640 field-years. Results showed no significant effects of cover crops on corn or soybean yields after controlling for weather and fertilizer use. However, farmers using cover crops for 3 or more years showed a positive but not statistically significant effect on soybean yields. The study aims to provide more conclusive data on cover crop costs and benefits to encourage farmer adoption, though larger and longer-term data may still be needed.
