1、What are the effects of foliar fertilization on tea quality and yield
Long-term production practices have shown that foliar fertilization not only improves the color, aroma, and taste of tea but also plays a positive role in increasing tea yield, effectively reducing the risk of excessive use of some root-applied fertilizers.
2、How Long Does a Single Application of Foliar Fertilizer on Tea Plants Last?
The foliar application of 2% urea or liquid amino acid fertilizer two times at the winter dormancy stage and two times at the spring dormancy stage showed the best performance in tea plants among the other foliar N fertilization methods, as it reduced the soil fertilization levels in tea plantations without decreasing the total N concentration ...
3、Increased organic fertilizer significantly increases leaf nitrogen and
In tea plantations, fertilization strongly influences the balance of these elements.
4、Foliar N Application on Tea Plant at Its Dormancy Stage Increases the N
Results showed that the foliar N application of amino acid liquid fertilizer two times at the winter dormancy stage was enough to significantly increase the N concentration of the mature leaves and improved the quality of spring tea.
Optimizing fertilization under varying cultivation conditions: Insights
This study investigates the impact of fertilizer management on tea yield and quality across different cultivation conditions primarily in China, providing critical insights for optimizing fertilization practices to promote sustainable production in the tea industry.
The Prolonged Application of Organic Fertilizers Increases the Quality
The substitution of chemical nitrogen (N) with organic fertilizers in tea plantations has been widely recognized as a strategy to maintain tea yield and improve soil quality, ensuring the sustainability of tea production systems.

Effects of balanced and unbalanced fertilisation on tea quality, yield
However, the effects of unbalanced fertilisation on tea production, that is, tea yield, quality, soil properties, and soil bacteria, have not been investigated, and the relationship between tea plants and soil characters remains unclear.
Effect of fertilization regime on tea yield, nutrient accumulation and
Fertilization is an important agricultural measure that improves not only tea yield and quality, but also soil quality; all of which sustain tea garden utility.
In tea plantations, foliar spraying of fertilizers is an effective method for nutrient application. It can rapidly replenish essential nutrients for plant growth, enhance tea quality, and boost yields. The yield-increasing effects of foliar fertilization depend on multiple factors, including fertilizer type, concentration, timing, and frequency of application. Below is a detailed analysis of its impact.
1. Types of Foliar Fertilizers
Foliar fertilizers are primarily categorized into nitrogen (N), phosphorus (P), and potassium (K) fertilizers. Each type has distinct effects on tea plant growth:
- (1) Nitrogen Fertilizer: Nitrogen is a macronutrient critical for promoting new shoot growth and leaf development. Spraying nitrogen fertilizer accelerates shoot elongation and increases tea yield.
- (2) Phosphorus Fertilizer: Phosphorus, a micronutrient, supports root growth and fruit development. Its application enhances root systems and improves tea quality.
- (3) Potassium Fertilizer: Potassium, another macronutrient, improves tea quality and disease resistance. Spraying potassium fertilizer strengthens plants against pathogens.
2. Fertilizer Concentration
Higher concentrations of foliar fertilizers generally yield more pronounced effects. excessive concentrations may cause leaf scorching and hinder growth. The optimal concentration should align with the tea’s growth stage and soil conditions.
3. Timing of Application
Foliar fertilization is most effective during peak growth periods when tea plants have higher nutrient demands. Application should avoid extreme weather (e.g., high temperatures or intense sunlight) to prevent foliage damage.
4. Frequency of Application
More frequent applications typically enhance yield gains. overapplication risks leaf burn and stunted growth. Frequency should be adjusted based on growth stages and soil nutrient levels.
5. Integration with Other Fertilization Methods
Combining foliar spraying with complementary practices maximizes results:
- Organic fertilizers improve soil structure and fertility.
- Soil conditioners balance pH for optimal growth.
- Irrigation systems ensure consistent water supply, boosting tea quality.
6. Key Considerations
- Fertilizer selection: Choose N, P, or K fertilizers tailored to growth stages and soil conditions.
- Avoid stress: Apply during cool periods (e.g., morning/evening) to prevent heat damage.
- Holistic approach: Pair foliar spraying with soil-based methods for comprehensive nutrient management.
Foliar fertilization is a rapid and efficient way to supplement tea plants with nutrients, enhancing both yield and quality. By optimizing fertilizer type, concentration, timing, and frequency—while integrating other soil and water management practices—tea growers can achieve sustainable productivity and superior leaf quality.
