Studying plant-soil interactions is significant in ecology because these relationships underpin ecosystem function and health. Plants influence soil composition, structure, and nutrient cycling through their root systems and organic matter. Conversely, soil provides essential nutrients and support, fostering plant growth. Understanding these interactions is crucial for managing ecosystems, enhancing agricultural productivity, and restoring degraded lands. Knowledge gained from these studies informs conservation efforts, indicating how practices like crop rotation and cover cropping can improve soil health and promote biodiversity. Ultimately, healthy plant-soil dynamics contribute to resilient ecosystems and sustainable agriculture.
