The study looked at how using rice and wheat straw in wheat fields affects soil fertility and nutrient levels. By returning straw to the fields, the soil's organic matter, nitrogen, and available nutrients increased, helping wheat plants grow better. This method improved nutrient supply during different stages of wheat growth, especially when rice straw was used in a single season or both rice and wheat straw in two seasons. This research shows that using straw in wheat fields can help increase crop yields and maintain soil fertility for future seasons.
