Preferred citation for this article: Liu Y., and Chen Y., 2024, Subsoiling treatment on soil permeability and its impact on the growth of sweet potato (Ipomoea atatas), International Journal of Horticulture, 14(1): 1-10 (doi: 10.5376/ijh.2024.14.0001) Abstract Subsoiling treatment is a crucial soil management practice that profoundly influences soil physical properties, especially soil permeability. This review aims to explore the impact of subsoiling treatment on soil permeability and sweet potato growth. It provides a comprehensive overview of subsoiling treatment methods, including mechanical, biological, and chemical approaches, emphasizing the pivotal role of soil permeability in field water management and crop growth. Furthermore, it delves into how subsoiling treatment enhances soil infiltration rates and water-holding capacity, creating favorable conditions for root growth and efficient water utilization by plants. The results highlight a significant improvement in soil permeability due to subsoiling treatment, reducing the risks of waterlogging and root water stress, thereby fostering an optimal growth environment for sweet potatoes. Moreover, subsoiling treatment positively impacts sweet potato yield, quality, and stress resilience. This review underscores the critical significance of subsoiling treatment as a soil management tool to enhance agricultural productivity and sustainability. Future research should delve deeper into the mechanisms of subsoiling treatment and explore best practices under varying soil and climatic conditions to support sustainable agriculture. Keywords Subsoiling treatment; Soil permeability; Sweet potato; Soil management; Agricultural production Sweet potato (Ipomoea batatas) is a globally important staple crop that has garnered attention due to its high yield, rich nutritional value, and widespread adaptability. As a staple food, sweet potatoes play a crucial role in the daily diets of many countries. The carbohydrates, vitamins, minerals, and dietary fiber found in sweet potatoes are widely recognized as effective tools in combating hunger and improving nutritional status (Prakash et al., 2016). Additionally, sweet potatoes are extensively utilized as a significant feed resource in livestock farming. Therefore, ensuring the production and quality of sweet potatoes is crucial, and the suitability and quality of the soil directly impact the growth and yield of sweet potatoes. Permeability is a key soil property in agricultural production, influencing soil water retention, drainage, and nutrient supply capacity (Garg et al., 2021). Good soil permeability can reduce the risk of waterlogging, promoting root growth and nutrient absorption in plants. Therefore, a profound understanding and improvement of soil permeability are crucial for farmland management and crop growth. This paper aims to delve into the effects of deep loosening treatments on soil permeability and their impact on the growth of sweet potatoes. By introducing the concept of deep loosening, including methods such as mechanical, biological, and chemical loosening, it provides readers with background information and foundational knowledge on deep loosening treatments. The analysis explores how deep loosening treatments affect soil structure, porosity, permeability, and water retention capacity, further revealing the close connection between deep loosening treatments and soil permeability. Additionally, the study investigates the impact of deep loosening treatments on the growth of sweet potatoes, including their influence on root development, yield, and quality. It is hoped that through this comprehensive analysis, valuable insights and references can be provided for the application of deep loosening treatments in improving soil quality, promoting sweet potato growth, and supporting sustainable agricultural production.
