This improvement helps reduce waterlogging and root waterlogging, enhances soil drainage capacity, provides better permeability for crop roots, and facilitates the supply of oxygen and beneficial microorganisms in the soil. The positive impact of subsoiling treatment on sweet potato growth is multifaceted.Subsoiling treatment promotes the growth of sweet potato roots, crucial for nutrient and water absorption by the plant. Increased soil porosity resulting from deep loosening provides more growth space for sweet potato roots, allowing them to explore nutrients and water resources deeper in the soil. This means sweet potatoes can more effectively obtain the necessary nutrients, supporting healthier growth and higher yields. Furthermore, subsoiling treatment improves the growth environment for roots. By increasing soil permeability, subsoiling treatment helps alleviate oxygen deficiency in the soil, ensuring that roots receive an adequate supply of oxygen. This is crucial for plant respiration and the activity of root microorganisms, contributing to the health and growth rate of sweet potatoes. In conclusion, subsoiling treatment plays a crucial role in improving soil quality, promoting sweet potato growth, and supporting sustainable agricultural production. However, further research is needed to deepen our understanding of subsoiling treatment, including its potential mechanisms and best practices under different soil types and climatic conditions. As a powerful soil management tool, subsoiling treatment is expected to play an even greater role in advancing agricultural sustainability in the future. In-depth research and implementation of subsoiling treatment will provide robust support for better utilization of soil resources, increased food production, ecological balance maintenance, and the achievement of sustainable agricultural goals.
