Drought can have a significant impact on crop yield, particularly for field crops that are not irrigated. It is generally believed that adopting a no-till management system conserves more soil moisture, but there is a lack of scientific data to support this recommendation, especially under different crop rotations. This project analyses ten years of field data and uses a computer model with historic data to assess the impact of no-till and tilled systems on soil moisture and crop yield reduction due to drought.
