Different soil tillage methods and cover crops can impact corn yield and soil characteristics. In a study, researchers tested conventional tillage, minimum tillage, and non-tillage, along with cover crops like Vicia villosa and Lathyrus sativus. They found that minimum tillage led to the highest corn yield, increasing it by 20% compared to conventional tillage. Planting cover crops also increased grain and biological yield. Additionally, using minimum tillage and cover crops improved soil structure by increasing organic matter and reducing bulk density. This suggests that using these methods can boost corn yield and enhance soil quality.
