Influence of Different Types of Organic Fertilizer on Tea Quality and Soil Nutrients

Abstract

The application of organic fertilizer is an important practice for enhancing tea quality. It plays a vital role in improving the physical and chemical properties of the soil, regulating the soil environment, and promoting the production of high-quality tea. This study evaluated the effects of six different fertilization treatments on tea quality and soil nutrients in tea gardens. The treatments included local conventional fertilization (T1) and five types of oil-dry organic fertilizers (T2, T3, T4, T5, and T6). The results showed that, compared to conventional fertilization (T1), tea leaves under T3 and T6 treatments exhibited the highest quality. Additionally, T2, T3, and T6 significantly improved the physical and chemical properties of the soil. These treatments effectively reduced soil acidification while enhancing the overall quality of the tea garden soil. Among the treatments, T3 demonstrated the most favorable results. It promoted tea tree growth, improved soil fertility, and significantly enhanced tea quality. This highlights the potential of organic fertilizers in addressing soil degradation and boosting tea production. These findings provide valuable insights into sustainable tea cultivation practices. The study establishes a reference for improving tea quality and optimizing soil management in tea gardens
