1、FERTILIZER USER GUIDE MANUAL FOR TEA

Fertilizer field experiments on tea in all major tea growing areas of Kenya have shown that the magnitude of the increase in yield tend to diminish, as the total level of fertilizer nutrient increases.

2、When Is The Best Time To Spray Foliar Fertilizer

The best times to apply foliar fertilizer are early morning or late afternoon, when temperatures are cooler and wind is low, allowing for optimal nutrient absorption and minimal evaporation.

3、Yueyang Experience in Spraying Foliar Fertilizer for Drought and Cold

Cold Resistance Spraying Time: Primarily targets varieties with weaker cold resistance, such as Golden Tea, or areas of the tea garden that are more prone to frost, such as wind-exposed sections.

4、Rational application of combined fertilizers improved tea growth and

Results: Compared to control, all fertilization treatments significantly improved tea growth, biomass, and quality components including soluble sugars, TAAs, catechins, caffeine, polyphenols and flavonoids in tea leaves.

Effects of Foliar Fertilizer Application on Quality of Tea (Camellia

Fertilizers improve the nutritional status of plants and soil for the plants. Tea is grown on recommended optimal soil conditions that are described as deep soils, well aerated with pH tending toward acidic (4.5 - 5.6 pH levels).

TN101 Foliar Fertiliser for Tea Crops

Tea readily responds to the application of nitrogen and potassium, with 10kg of nitrogen, 5kg of potassium and 2kg of phosphorus being applied for every 100kg of tea.

Efficient use of Fertilizer in Tea

Soil temperature affects the fertilizer efficiency by changing solubility of fertilizers, concentration of solubilized fertilizer cation exchange and also ability of the plants to absorb and use of nutrients.

Foliar N Application on Tea Plant at Its Dormancy Stage Increases the N

Recently, Ma et al. (2019) reported that tea plants can take up N at low winter temperatures under field conditions. The foliar spraying of N fertilizer usually occurs 2 weeks before the sprouting of dormant buds, or during the harvesting period of spring tea.

Foliar fertilizers for tea are designed to promote growth and enhance the quality of tea leaves. When applying these fertilizers, several key points should be considered:

1. Select the Appropriate Fertilizer: There are various types of tea foliar fertilizers, including nitrogen, phosphorus, and potassium formulations. Choose based on the tea's growth stage and nutritional needs. Spring and autumn are generally ideal times for application.

2. Proper Dilution: Dilute the foliar fertilizer according to the manufacturer's recommended ratio. Avoid over-concentration to prevent damage to the tea leaves. Use water or a dedicated diluent for mixing.

3. Optimal Timing: Apply in the morning or evening when there is no direct sunlight. Calm or mild wind conditions are preferable to minimize drift and loss.

4. Uniform Application: Use a sprayer to evenly distribute the fertilizer across the leaf surface. Take care not to spray directly onto the stems, which could hinder growth.

5. Control Dosage: The amount applied depends on the tea's growth status and fertilizer type. Typically, 1-2 kilograms per mu (approx. 0.067 hectares) is sufficient. Excessive use may lead to overly vigorous growth, compromising quality.

6. Safety Precautions: Wear personal protective equipment (PPE) to avoid skin and eye contact. Store and handle fertilizers properly to ensure stability.

7. Regular Application: Follow a "small amounts, frequent applications" principle. Monthly application is common, but adjust frequency based on specific growth conditions and fertilizer type.

8. Combine with Other Fertilizers: Complement tea foliar fertilizers with others like potassium dihydrogen phosphate or urea for enhanced results.

9. Monitor Response: Observe the tea's growth and fertilizer effectiveness closely. If excessive growth or reduced quality occurs, adjust dosage and application methods promptly.

effective use of tea foliar fertilizers involves selecting the right product, proper dilution, timely application, uniform spreading, controlled dosage, safety measures, regular but measured use, complementary fertilization, and ongoing observation. By following these guidelines, tea farmers can improve both the quality and yield of their crop, enhancing economic benefits.
