1、The effects of chemical and organic fertilizer usage on rhizosphere

The objective of this study was to assess the effects of long-term use of chemical and organic fertilizers on tea and rhizosphere soil properties in tea orchards.

2、Influence of Organic and Inorganic Fertilizers on Tea Growth and

Organic-based fertilizers have been ratified to be effective in ameliorating tea growth and the fertility of soil. However, the effect of integrated fertilization on tea growth and quality and the chemical properties of the soil in tea gardens are unclear.

3、Effects of organic fertilizer substitution for chemical fertilizer on

Fertilizers are critical for tea cultivation; however, consensus is lacking on the mechanisms by which organic fertilizer substitution affects yield and quality of tea leaves.

4、THE EFFECTS OF FERTILIZER ON SOIL FOR TEA PRODUCTION

The long-term use of chemical and fertilizers was assessed on tea crop and rhizosphere soil properties in tea orchards. The heavy metals and bacterial composition were analysed by spectroscopy in rhizosphere soils.

5、The effects of chemical and organic fertilizer usage on

The objective of this study was to assess the effects of long-term use of chemical and organic fertilizers on tea and rhizosphere soil properties in tea orchards.

Application of Tea

In this study, a field experiment was conducted with four different fertilization treatments, including a combined tea-specific fertilizer plus a fixed rate of urea with or without an organic fertilizer.

Influence of Organic and Inorganic Fertilizers on Tea Growth and

A comprehensive understanding of the impact of organic fertilizers on tea growth, quality, and soil characteristics may provide new insights into improving tea production, quality, and soil management practices in tea gardens.

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.

Green manuring orchards and tea gardens: concept, effects, and application

Fruit orchards and tea gardens in China are often established in sites with poor field conditions, farmed by clean tillage, and are popularly and excessively reliant on chemical fertilizers, leading to severe soil and nutrient losses, as well as soil degradation and decline of fruit and tea quality.

Tea residue fertilizer is an organic fertilizer primarily composed of leftover tea residues and byproducts. Rich in essential nutrients such as nitrogen, phosphorus, and potassium, it plays a vital role in improving soil fertility, enhancing soil structure, and promoting crop growth. Using tea residue fertilizer in orchards effectively increases soil organic matter content, boosts water retention and nutrient-holding capacity, improves soil structure, stimulates root development of fruit trees, and enhances disease and pest resistance, ultimately increasing yield and fruit quality.

I. Methods for Applying Tea Residue Fertilizer

1. Select Suitable Tea Residue Fertilizer: Choose reliable, well-balanced products, preferably fermented tea residue fertilizer, as fermented forms are more easily absorbed and utilized by the soil.

2. Timing of Application: The optimal time is after fruit harvest in autumn, when root activity slows, allowing for better decomposition and absorption of the fertilizer.

3. Application Method:

   • Evenly spread the fertilizer within the tree canopy projection area, followed by deep soil tilling to ensure thorough mixing.
   • For young trees, directly apply the fertilizer into the planting hole.
   • For mature trees, spread the fertilizer evenly over the soil surface within the canopy area and then deep-till the soil.

4. Dosage: Adjust based on tree growth and soil fertility. Generally, apply 20–50 kg per mu (approx. 0.067 hectares) of orchard.

5. Frequency:

   • For young trees: Apply once annually before bud sprouting in spring.
   • For mature trees: Apply once annually after fruit harvest in autumn.

6. Precautions:

   • Avoid overapplication to prevent excessive soil salinity or structural damage.
   • Do not mix with chemical fertilizers, as this may reduce effectiveness.

II. Impact of Tea Residue Fertilizer on Fruit Tree Growth

1. Enhances Soil Fertility: Rich in essential nutrients, it boosts soil organic matter and nutrient-holding capacity, providing ample nourishment for trees.

2. Improves Soil Structure: Organic matter increases soil porosity, facilitating root growth and nutrient absorption.

3. Stimulates Root Development: Organic components promote root growth, strengthening the tree’s ability to absorb water and nutrients while improving pest and disease resistance.

4. Increases Yield and Quality: By enriching soil fertility and structure, tea residue fertilizer supports healthier root systems and nutrient uptake, leading to higher yields and superior fruit quality.

Tea residue fertilizer is a high-quality organic option that significantly improves soil health, water retention, and tree resilience in orchards. Its use enhances productivity and fruit quality, making it a highly recommended practice for sustainable orchard management.
