1、Boron Fertilizers

Soils deficient in Boron can be amended with boron fertilizer such as Borax, boric acid, and Solubor (Table 1.4), based on soil tests and crop requirements. As was stated before, due to the narrow margin between B deficiency and toxicity, an excess rate can easily happen and injure the plant growth (Marschner, 2011).

2、Boron in Soils and Plant Nutrition

Boron is essential in the actively growing regions of plants, such as root tips and in new leaf and bud development. This involves the meristematic (growing) tissues in plants or the cells that are rapidly multiplying, allowing plant growth to occur.

How to fertilize the latest Pueraria lobata 02/23 Update MySheen

Base fertilizer is generally combined with soil preparation, base fertilizer can be said to be half of the total amount of fertilizer, and it is mainly organic fertilizer, combined with an appropriate amount of inorganic fertilizer.

Effects of organic fertilizer application on dry matter, nutrient

The treatments with organic fertilizer can continuously supply nutrients for Pueraria thomsonii benth at the middle and late growth stages, improve the nutrient accumulation of root tubers, and thereby improve root tuber yield of Pueraria lobata root, especially the CM treatment.

Importance of Boron in Plant Growth

Sufficient Boron for Better Root Uptake of Phosphorus and Potassium. Studies show that adequate B nutrition improves root uptake of phosphorus (P) and potassium (K) by maintaining proper function (through ATPase activity) and structure of root cell membranes.

Effects of Organic Fertilizer on Nutrient Elements, Yield and Quality

The yield and commercial rate of tuberous root of P. thomsonii were increased with the application of organic fertilizer, except A2, the yield of A1, A3, A4 and A5 was increased by 10.46%, 5.99%, 14.98% and 7.17%, respectively.

Plants And Boron: Using Boron In The Garden

Deep watering will relieve heavy boron soil concentrations by leaching the nutrient away from the roots. In good soil, this leaching won't cause boron deficiency in plants. The organic material used to enrich and fortify the earth will release the micronutrient back into the soil.

Pueraria seedlings and planting techniques

The application of 1000 kg per acre can be properly applied with urea, and the winter fertilizer after defoliation is mainly based on farmyard manure. The annual growth period can be combined with watering, and a small amount of potassium fertilizer can promote root growth. 5.

Pueraria root, also known as Pueraria lobata, is a plant widely cultivated in Asia, particularly in China, Japan, and South Korea. It holds significant medicinal value and is extensively used in food processing and health product production due to its rich nutritional content. Below, we explore the possibility, benefits, application methods, and precautions of using boron fertilizer for pueraria root cultivation.

1. Growth Requirements of Pueraria Root

Understanding pueraria root’s growth needs is essential for rational fertilization. This plant thrives in warm, humid environments and prefers soil with a pH between 5.5 and 7. While it is not overly sensitive to light, adequate sunlight promotes healthier growth. In terms of nutrients, pueraria root requires balanced amounts of nitrogen (N), phosphorus (P), and potassium (K):

• Nitrogen supports leaf development.
• Phosphorus aids root growth.
• Potassium enhances disease resistance.

2. The Role and Importance of Boron Fertilizer

Boron is a vital micronutrient for plants, playing key roles in cell division, elongation, and photosynthesis. For pueraria root, boron fertilizer:

• Stimulates root system development.
• Improves disease resistance.
• Enhances fruit quality. In boron-deficient soils, applying boron fertilizer can rapidly alleviate growth issues.

3. Application Methods of Boron Fertilizer

a. Selecting Boron Fertilizer Types

Choose the right boron fertilizer based on the crop’s growth stage, soil conditions, and environmental factors:

• Solid borax (e.g., sodium borate) is suitable for soil application.
• Liquid boric acid works well for foliar spraying.

b. Timing of Application

Apply boron fertilizer during critical growth stages:

• Early growth stages (e.g., sprouting) yield the best results, as boron absorption is highest.
• Later stages (flowering or fruit maturation) may still benefit but are less optimal.

c. Dosage and Methods

• Dosage: Follow soil test results and label recommendations to avoid overapplication.
• Methods:
  • Base application: Mix boron fertilizer into the soil during land preparation.
  • Topdressing: Apply during key periods like pre-flowering.
  • Foliar spraying: Dilute boron fertilizer and spray directly onto leaves.

4. Precautions

a. Avoid Mixing with Other Fertilizers

Mixing boron fertilizer with other nutrients may reduce efficacy or cause adverse reactions. Always check compatibility before use.

b. Soil pH Matters

Pueraria root prefers soil with a pH of 5.5–7. Highly acidic or alkaline soils can reduce boron availability. Test and adjust soil pH as needed.

c. Monitor Plant Response

After applying boron fertilizer, observe plants closely. Symptoms like yellowing leaves or stunted growth may indicate overapplication or misuse. Adjust practices promptly.

Pueraria root can benefit from boron fertilizer, but success depends on careful selection of fertilizer type, timing, and application method. Avoid mixing with incompatible fertilizers, monitor soil pH, and observe plant reactions to ensure safety and effectiveness. With scientific fertilization management, boron can enhance pueraria root’s quality and yield, contributing to agricultural productivity and economic returns.
