1、Absorption of foliar

Solution and pot experiments were conducted with the objective to evaluate the utilization efficiency of foliar applied urea and the impact of plant nitrogen (N), potassium (K), magnesium (Mg) and sulfur (S) nutritional status.

2、Nutrient Deficiency and Abundance in Tea Plants: Metabolism to Productivity

Inorganic fertilizer requirement for young tea plants can be reduced by use of poultry manure, while the mature tea chemical fertilizer requirement can be minimized or avoided by use of cow dung as the mature tea plants require more N and P compared to the younger ones (Sultana et al. 2014).

3、Effects of Foliar Fertilizer Application on Quality of Tea (<I>Camellia sinensis</I>) Grown in the Kenyan Highlands

A fertilizer trial test was established in three sites of the major tea growing regions, with 36 plots per site to determine the effects of foliar fertilizer application on tea quality.

Correction of magnesium deficiency in tea plants through foliar applications

A trial foliar applications of 0, 5, 10, 20, and 30% of magnesium oxide (MgO) solution was carried out using three replications. The result indicated that a 30% Mg solution could correct Mg deficiency in tea plants within 14 days of spraying and the growth rate increased by 16 to 134.5%.

Effects of magnesium deficiency on photosynthesis and carbohydrate partitioning

We hereby review all these aspects with a special emphasis on the role of Mg in photosynthesis and the structural and functional effects of its deficiency on the photosynthetic apparatus. Magnesium (Mg) is a macronutrient often forgotten in crop production (Cakmak and Yazici 2010).

Magnesium Regulation Increases the Content of Characteristic Volatile Compounds and Enhances the Intensity of Odor Characteristics in Tea Tree Leaves

In this study, the volatile compounds of tea leaves under different magnesium concentrations were determined to obtain the characteristic volatile compounds that changed significantly and their odor characteristics and to explore the effect of magnesium regulation on the aroma quality of tea leaves.

Effects of Foliar Fertilizer Application on Quality of Tea (Camellia sinensis) Grown in the Kenyan Highlands

Therefore, the aim of this study was to investigate foliar fertilizer Nitrogen, Phosphorus and potassium (NPK) uptake in dif-ferent tea varieties in Kenya and determine its effects on tea quality changes and the levels of nutrient residues in tea leaf after foliar fertilizer application.

When tea plants lack magnesium, foliar spraying with fertilizers is an effective supplemental measure. Foliar fertilizers are directly absorbed through leaves, rapidly increasing magnesium levels within the plant. To select the most appropriate fertilizer, consider the following aspects:

1. Types of Foliar Fertilizers:

   • Magnesium Sulfate: One of the most common magnesium fertilizers, as it is an inorganic salt form of magnesium easily absorbed by plants. excessive use may lead to magnesium ion imbalance in the soil, affecting other nutrients.
   • Chelated Magnesium: This form is more stable and less prone to soil fixation, making it ideal for foliar application.
   • Seaweed Extract: Rich in magnesium from seaweed, easily absorbable by plants and environmentally friendly.
   • Amino Acid Chelates: These fertilizers contain microelements that enhance magnesium absorption in plants.

2. Fertilizer Concentration:

   • Typically, dilute foliar fertilizers at 10–20 mL per liter of water. Adjust concentrations based on product instructions and the plant’s specific needs.

3. Timing of Application:

   • Apply foliar sprays in the morning or evening to avoid direct sunlight, as high temperatures may accelerate evaporation and waste the fertilizer.
   • After spraying, immediately shade the area (e.g., with a shade net) to prevent rapid moisture loss.

4. Application Method:

   • Use a sprayer to evenly coat leaves, ensuring all surfaces contact the fertilizer.
   • Consider wind direction and speed to avoid drift or dispersion onto non-target plants.

5. Frequency of Application:

   • Depending on plant health, soil conditions, and fertilizer type/concentration, apply weekly for 3–5 consecutive treatments.

6. Precautions:

   • Test small areas first to determine optimal usage.
   • Monitor plants for signs of stress (e.g., leaf yellowing, stunted growth) and halt use if issues arise. Consult professionals if needed.
   • Avoid overreliance on foliar sprays. Complement with soil fertilization and irrigation to meet overall nutrient needs.

7. Soil Management:

   • While applying foliar fertilizers, maintain soil health by improving structure and organic matter, which aids magnesium uptake.
   • Regularly test soil magnesium levels to adjust fertilization strategies.

8. Combining with Other Fertilizers:

   • Pair foliar fertilizers with supplements like phosphorus or potassium to boost overall plant nutrition.
   • Avoid mixing multiple fertilizers simultaneously to prevent overapplication or interactions.

9. Environmental Protection:

   • Choose eco-friendly fertilizers (e.g., biodegradable options or non-hazardous chemicals) to minimize environmental impact.

following these steps and precautions ensures effective magnesium supplementation for tea plants, promoting healthy growth.
